The Cardiometabolic Blueprint

Two kinds of fiber

Insoluble fiber (wheat bran, vegetable skins) works like a broom. It mainly helps digestion and regularity. Soluble fiber dissolves in water and forms a gel in your gut. That gel is the type that affects cholesterol.

How soluble fiber lowers LDL

Your liver uses cholesterol to make bile, which helps digest fat. Normally most of that bile is recycled. Soluble fiber's gel traps some bile so it leaves the body instead. To replace it, your liver pulls more LDL out of your bloodstream. The result is a modest but real drop in LDL cholesterol.

How much makes a difference

Research suggests that getting about 5–10 grams of soluble fiber a day is linked to roughly a 5% reduction in LDL, and more can lower it further. That may sound small, but it adds up when combined with other changes, and the foods that provide it also support blood sugar and fullness.

Most adults get only a few grams of soluble fiber a day. Total fiber recommendations are about 25 g a day for women and 38 g for men, and most people fall well short.

The best sources

• Oats and oat bran, rich in a soluble fiber called beta-glucan. About 3 g of beta-glucan a day (roughly 1½ cups of cooked oatmeal) is the amount linked to LDL lowering.
• Beans and lentils: black, kidney, navy, pinto, chickpeas.
• Certain fruits: oranges, pears, apples, berries.
• Certain vegetables: Brussels sprouts, broccoli, sweet potatoes, carrots.
• Ground flaxseed and psyllium husk

A simple day with about 7–8 grams

Start small

• Add one food at a time. Increasing fiber quickly can cause gas or bloating. Build up over 2–3 weeks.
• Drink more water as you add fiber.
• If you use a psyllium supplement, take it a couple of hours apart from medications, because it can affect how some are absorbed. Check with your pharmacist or provider.

Cholesterol itself isn't the problem

Your body needs cholesterol. It uses it to build cell walls, make hormones and produce vitamin D. Because cholesterol is a fat, it can't float freely in your blood. It travels inside particles called lipoproteins. Think of them as delivery trucks.

Some of those trucks, mainly LDL particles, can slip into the artery wall and get stuck. Over years, those stuck particles contribute to plaque. That's why the number and type of particles matter so much for heart health.

LDL cholesterol (LDL-C): the cargo

The standard "LDL" on a lab report is LDL cholesterol: how much cholesterol is being carried inside your LDL particles. It's the most-studied cholesterol number, and lowering it is linked with lower cardiovascular risk. US guidelines describe under 100 mg/dL as optimal, 130–159 as borderline high, 160–189 as high, and 190 or above as very high.

ApoB: the number of trucks

Every particle that can build plaque carries exactly one protein called apolipoprotein B (ApoB). So an ApoB test is essentially a particle count.

Most of the time, LDL-C and ApoB tell the same story. But they can disagree. This happens most often in people with higher triglycerides, insulin resistance or extra weight around the waist. Their LDL-C can look "normal" while their particle count is high, because the cholesterol is packed into more, smaller particles. That's why many experts see ApoB as a sharper measure of risk.

There's no single "right" ApoB for everyone. The target depends on your overall cardiovascular risk, which is something to review with your healthcare provider.

Lp(a): the inherited particle

Lipoprotein(a), or Lp(a), is a special type of LDL-like particle. Your level is largely set by your genes, so it tends to stay fairly stable through life. Diet and exercise don't change it much. Some health conditions and life stages (such as kidney disease or menopause) can shift it, and results vary by lab method and units.

US guidelines consider an Lp(a) of 50 mg/dL (about 125 nmol/L) or higher a "risk-enhancing factor." Many expert groups now recommend testing it at least once in adulthood. If yours is elevated, the practical message is: everything else you can control matters even more, and your provider should know about it.

Non-HDL cholesterol: a useful shortcut

If you don't have ApoB, non-HDL cholesterol (total cholesterol minus HDL) is a good stand-in. It captures cholesterol in all the plaque-building particles, not just LDL. The Lab Analyzer calculates it for you.

What you can change

Lp(a) is mostly inherited, but LDL-C and ApoB respond to daily habits. The three food levers in this module are:

1. More soluble fiber (Lesson 2)
2. Swapping saturated fats for unsaturated fats (Lesson 3)
3. Building a heart-healthy eating pattern, including oily fish (Lesson 4)

Movement, waist size, sleep and blood sugar also affect your particles. They're covered in the other modules. Your Action Map shows which levers to start with, based on your results and habits.

Not all fats act the same

Saturated fats are mostly solid at room temperature: butter, cheese, cream, fatty and processed meats, coconut and palm oil. Unsaturated fats are mostly liquid: olive oil, avocado, nuts, seeds and fish.

Your liver clears LDL from your blood using LDL receptors, like docking stations. Eating a lot of saturated fat tends to reduce the number of active docking stations, so more LDL stays in circulation. Unsaturated fats don't have that effect.

The replacement rule

This is the part most people miss. Cutting saturated fat helps your heart only if you replace it with something better.

• Replacing it with unsaturated fats (olive oil, nuts, seeds, avocado, fish) lowers LDL and is linked to lower cardiovascular risk. Polyunsaturated fats (walnuts, flax, sunflower seeds, fish) appear especially helpful.
• Replacing it with high-fiber foods like beans, whole grains and vegetables also helps.
• Replacing it with refined carbs and sugar (fat-free cookies, white bread, sweetened yogurt) doesn't improve heart health, and can raise triglycerides.

So the goal isn't "low fat." It's trading the fats.

How much is "a lot"?

The US Dietary Guidelines suggest keeping saturated fat under 10% of daily calories. For people working to lower LDL, the American Heart Association suggests about 5–6%. On a 2,000-calorie day, that's roughly 13 grams. For reference, one tablespoon of butter has about 7 grams.

You don't need to count grams. Focus on swapping the foods you eat most often.

Where saturated fat usually comes from

• Fatty and processed meats: sausage, bacon, salami, burgers, ribeye
• Full-fat dairy: butter, cream, cheese, ice cream
• Baked goods and pastries: croissants, muffins, cookies
• Restaurant and fast food: pizza, fried foods, creamy sauces
• Coconut and palm oil

Five swaps with the biggest payoff

1. Butter → olive oil or avocado oil for cooking.
2. Processed meats → chicken, fish, beans, or lean turkey for sandwiches and breakfasts.
3. Fatty red meat → leaner cuts (sirloin, 93% lean ground), or half beef and half lentils in recipes.
4. Cream and full-fat cheese → lower-fat versions, or smaller amounts of strong-flavored cheese.
5. Pastries and sweets → nuts, fruit, or whole-grain toast with nut butter.

The Saturated Fat Swap Guide has a full swap table and a quick guide to reading food labels.

If your LDL went up on keto or carnivore

Some people see a big rise in LDL and ApoB on very-low-carb, high-saturated-fat diets, even while they lose weight and their triglycerides improve. People respond very differently. If this happened to you, you don't need to give up lower-carb eating. Shifting your fats toward olive oil, nuts, avocado and fish often makes a meaningful difference. Recheck your labs and review them with your provider.

What about eggs and dietary cholesterol?

For most people, saturated fat raises LDL more than the cholesterol in food does. Some people are more sensitive to dietary cholesterol. If you eat a lot of eggs and your LDL is high, it's reasonable to test cutting back and recheck.

Sources: Sacks FM, et al. AHA Presidential Advisory on Dietary Fats and CVD (2017); AHA/ACC 2013 Lifestyle Guideline (5–6% saturated fat); Dietary Guidelines for Americans 2020–2025; Hooper L, et al. Cochrane Review (2020).

Why fish is in this module

Oily fish such as salmon, sardines, trout, herring and mackerel are rich in omega-3 fats (EPA and DHA). Diets that include fish regularly are linked to better heart health, and the American Heart Association recommends about two servings a week (about 3.5 oz cooked per serving), especially oily fish.

Being honest: omega-3s don't lower LDL much

Omega-3s are best known for lowering triglycerides. They don't meaningfully lower LDL cholesterol. Fish helps your LDL mainly through what it replaces. A salmon dinner instead of sausage, burgers or a cheesy casserole cuts saturated fat (Lesson 3) and adds healthy unsaturated fat at the same time.

That's why we call this action optional. It's a food-quality upgrade, not a substitute for the fiber and fat-swap steps, or for any treatment your provider recommends.

Best choices (lower mercury)

• Salmon (fresh, frozen or canned)
• Sardines, Atlantic mackerel, herring, anchovies
• Rainbow trout

Limit high-mercury fish such as king mackerel, shark, swordfish, marlin, orange roughy, tilefish and bigeye tuna. If you're pregnant, planning to become pregnant or breastfeeding, follow the FDA/EPA fish advice for your situation.

Easy ways to start

• Canned salmon or sardines on whole-grain crackers or a salad
• Sheet-pan salmon with vegetables (about 20 minutes)
• Swap one burger night for salmon burgers
• Grilled trout or fish tacos with cabbage slaw

Don't eat fish?

• Walnuts, ground flaxseed, chia seeds and hemp seeds provide a plant omega-3 (ALA). Your body converts only a small amount to EPA/DHA, but these foods also add fiber and unsaturated fat.
• For LDL, the bigger wins are still soluble fiber and fat swaps.
• Fish-oil supplements aren't a replacement for these habits. Discuss them with your provider before starting, especially if you take blood thinners or have a heart rhythm condition.

The bigger picture: food quality

Fish is one piece of a heart-healthy pattern: mostly minimally processed foods, plenty of vegetables, fruits, beans and whole grains, unsaturated fats, and fewer processed meats and sweets. You don't need a perfect diet. A few consistent swaps each week is what moves the numbers.

Sources: AHA Science Advisory on Seafood Long-Chain n-3 PUFAs (2018); FDA/EPA Advice about Eating Fish (2021 update); AHA 2021 Dietary Guidance; Skulas-Ray AC, et al. AHA Science Advisory on omega-3s and triglycerides (2019).

What triglycerides are

Triglycerides are the main way your body stores and moves energy as fat. After a meal, your body packages fat from food into triglycerides. Between meals, your liver makes its own triglycerides, especially from extra sugar, refined carbs and alcohol, and sends them out in particles called VLDL.

Some triglyceride in your blood is normal. The concern is when levels stay high. The particles that carry triglycerides, and the "remnants" they leave behind, carry ApoB, the same protein found on LDL. That means they can also contribute to plaque.

The numbers

Most tests are done fasting, but non-fasting tests are now common too. Triglycerides run a little higher after eating, so compare results taken the same way. Very high levels (500 or above) are a separate concern because they raise the risk of pancreatitis, an inflammation of the pancreas.

HDL: the "cleanup crew"

HDL particles help carry cholesterol away from tissues and back to the liver. Low HDL (under 40 mg/dL for men, under 50 for women) is linked with higher cardiovascular risk.

But here's what changed: medications that raised HDL didn't reduce heart attacks in large trials. So today, HDL is seen mainly as a signal of how your metabolism is working, not a number to chase directly. Low HDL usually travels with high triglycerides, extra waist fat and insulin resistance. When those improve, HDL often moves too. And very high HDL isn't automatically protective, so "higher is always better" isn't the right way to think about it.

Why they move together

When your liver is making a lot of triglyceride-rich particles, they swap cargo with HDL and LDL. HDL particles lose cholesterol and get cleared faster (so HDL drops), and LDL particles become smaller and more numerous (so ApoB rises). That's why high triglycerides, low HDL and high ApoB often show up together, and why they all tend to improve together.

The triglyceride-to-HDL ratio shown in your Lab details is a simple way to see this pattern. It's useful context, but there's no universally accepted cutoff, so we show it for information only.

What moves triglycerides

Triglycerides are one of the most habit-responsive numbers on a lipid panel. The biggest levers are:

1. Less added sugar and refined carbs (Lesson 2)
2. Less alcohol, if you drink (Lesson 3)
3. More structured, home-built meals (Lessons 4 and 5)
4. Regular movement, which helps your muscles use fat and sugar for fuel (Blood Sugar & Insulin module)
5. Losing some waist fat, if you carry extra
6. Oily fish, which provides omega-3 fats (LDL module, Lesson 4)

Because the liver responds quickly, many people see triglycerides change within a few weeks of consistent changes. Your Action Map shows which levers to start with.

Sources: NCEP ATP III (2002); Miller M, et al. AHA Scientific Statement: Triglycerides and Cardiovascular Disease (2011); 2018 AHA/ACC Cholesterol Guideline; AIM-HIGH (2011) and HPS2-THRIVE (2014) trials; Nordestgaard BG, et al. EAS/EFLM non-fasting lipid consensus (2016).

From sugar to blood fat

When you eat more sugar and fast-digesting carbs than your body needs right away, your liver turns some of the extra into fat. It packages that fat as triglycerides and releases it into your blood. Fructose, found in table sugar, syrups and sweetened drinks, is especially easy for the liver to convert.

That's why some people who already eat "low fat" still have high triglycerides. The issue is often the sugar and refined starch, not the fat.

Drinks are the biggest lever

Sugary drinks like soda, sweet tea, sweetened coffee drinks, energy drinks and juice deliver a lot of sugar quickly, without fiber or protein to slow it down. For many people, cutting back on sweetened drinks is the single easiest change with the biggest effect.

How much added sugar?

The American Heart Association suggests limiting added sugar to about 25 grams a day for women and 36 grams for men (roughly 6 and 9 teaspoons). One 20-oz soda has about 65 grams. You don't need to count every gram. Start by checking the "Added sugars" line on the labels of foods you buy often.

Whole fruit is different. Its fiber and water slow the sugar down, and fruit is part of a heart-healthy pattern. If your triglycerides are high, favor whole fruit over juice and dried fruit.

Refined vs. fiber-rich carbs

You don't have to give up carbs. Swapping refined carbs for fiber-rich ones, and pairing carbs with protein and vegetables, makes a real difference for both triglycerides and blood sugar.

Watch the "fat-free" trap

Many low-fat and fat-free products replace fat with sugar. If you cut saturated fat (LDL module, Lesson 3), replace it with unsaturated fats or fiber-rich foods, not sweetened low-fat versions.

Three swaps to start

1. Replace one sweetened drink a day with water, sparkling water, or unsweetened tea or coffee.
2. Upgrade one refined carb to a fiber-rich version (for example, white rice → brown rice or beans).
3. Build one meal a day as a balanced plate using the Meal Builder: half vegetables, a palm of protein, a fist of fiber-rich carbs.

How alcohol raises triglycerides

Your liver treats alcohol as a priority. While it's processing alcohol, it burns less fat and makes and releases more triglyceride-rich particles. Alcohol also adds calories and often comes with high-sugar mixers and late-night snacks.

The effect is larger when you drink with a high-fat meal, when you drink more than a couple of drinks at a time, and in people whose triglycerides are already high. Some people's triglycerides are very sensitive to alcohol. Others' barely move. Your own labs are the best guide.

What counts as a drink

One standard drink is about 12 oz of regular beer, 5 oz of wine, or 1.5 oz of distilled spirits. Many restaurant pours and craft beers are closer to 1.5–2 standard drinks.

"Isn't some alcohol good for your heart?"

Older studies suggested that light drinkers had fewer heart problems, and alcohol can raise HDL slightly. Newer research suggests much of that apparent benefit came from how the studies were designed. Health organizations don't recommend starting to drink for heart health. If you don't drink, there's no reason to start.

You decide what to change

You don't have to quit to see a difference. Options that work well:

• Alcohol-free days: pick 2 or 3 set days a week.
• Set a number before you start, and alternate each drink with water.
• Choose lower-sugar options: skip sweet mixers, cocktails and dessert wines.
• Try a 4-week experiment: cut back noticeably, then recheck your triglycerides to see how your body responds.
• Have a go-to alternative: sparkling water with citrus, non-alcoholic beer, or a mocktail.

If your triglycerides are 500 mg/dL or higher, guidelines recommend avoiding alcohol completely. Review that with your provider.

Why it matters

Restaurant and packaged meals are often bigger, and higher in refined carbs, added sugar, saturated fat and salt, than what you'd make at home. Drinks, bread baskets and sides add up fast. None of that means you have to stop eating out. It means having a plan.

The 4-part ordering formula

1. Start with protein: grilled chicken, fish, shrimp, lean steak, eggs, tofu or beans.
2. Add vegetables: a side salad, steamed or roasted vegetables, or extra veggies in the dish.
3. Pick one smart carb, or a smaller portion: beans, brown rice, a baked potato or whole-grain bread, rather than fries plus bread plus dessert.
4. Choose your drink on purpose: water, sparkling water, or unsweetened tea or coffee.

Bonus moves: ask for sauces and dressings on the side, choose grilled over fried, and box half the meal before you start if portions are large.

Convenience food at home

• Frozen meals: look for at least 15 g protein, 4+ g fiber, and low added sugar. Add a bag of steamed vegetables.
• Rotisserie chicken + bagged salad + microwave brown rice or canned beans is a 5-minute dinner.
• Keep "backup" foods stocked: eggs, canned fish, canned beans, frozen vegetables, whole-grain wraps.

Two easy home meals

Pick two simple meals you can make on autopilot, for example a sheet-pan chicken and vegetables, and a bean-and-veggie burrito bowl. Having them ready makes it easier to skip the drive-through on busy nights. The Seven-Day Meal Planner has 15-minute options.

Sources: Dietary Guidelines for Americans 2020–2025; AHA 2021 Dietary Guidance to Improve Cardiovascular Health; Miller M, et al. AHA Triglycerides Statement (2011).

Why structure helps

When meals are skipped or unplanned, it's common to get very hungry, then grab whatever is fast: often refined carbs, sweets or takeout. Over time, that pattern makes it harder to keep triglycerides and blood sugar steady. Structure isn't about rigid rules. It's about removing the guesswork.

The balanced-plate template

• Half the plate: non-starchy vegetables
• A quarter: protein (about a palm-sized portion)
• A quarter: fiber-rich carbs (beans, whole grains, starchy vegetables, fruit)
• Plus: a small amount of healthy fat (olive oil, nuts, avocado)

Use it for most meals. It doesn't need to be perfect.

A rhythm that works

• Aim for regular meals at roughly similar times. For most people that's 3 meals, plus a planned snack if needed.
• Don't skip and then overeat. If you're often starving by late afternoon, add a protein-based snack.
• Plan tomorrow tonight. Five minutes to decide tomorrow's meals prevents most last-minute choices.
• Cook once, eat twice. Make extra dinner for the next day's lunch.

Intermittent fasting or time-restricted eating can work for some people, but it isn't required. Consistency matters more than timing.

How blood sugar is managed

When you eat carbohydrates, they're broken down into glucose (sugar) that enters your blood. Your pancreas releases insulin, a hormone that signals your muscles, liver and fat tissue to take that glucose in, either to use for energy or to store. After a typical meal, most of that glucose ends up in your muscles.

What insulin resistance means

Insulin resistance means your cells respond less strongly to insulin. To keep blood sugar steady, your pancreas makes more of it. For years, this extra insulin can keep glucose in a normal range, so standard tests may look fine while your body is working harder behind the scenes.

Over time, if the pancreas can't keep up, glucose starts to rise: first into the prediabetes range, and for some people into the diabetes range. Insulin resistance also tends to travel with higher triglycerides, lower HDL, more waist fat and higher blood pressure, which is why this module connects closely to the others.

Common contributors include low physical activity, long periods of sitting, extra fat around the waist, diets high in refined carbs and sugar, short or poor sleep, family history and age.

The numbers

A few important points:

• Only a healthcare provider can diagnose prediabetes or diabetes. A diagnosis usually needs a confirming test.
• Fasting insulin and HOMA-IR have no universally accepted cutoffs. They're most useful as context alongside A1c, glucose and triglycerides, and for tracking your own trend over time. A "typical" insulin result can't rule insulin resistance in or out.
• A1c can read falsely high or low with some conditions, such as anemia or iron deficiency, kidney disease, recent blood loss or transfusion, pregnancy, and some inherited hemoglobin variants. If your A1c and glucose don't seem to match, ask your provider.

Why prediabetes is an opportunity

The prediabetes range is the stage where habits make the biggest difference. In the large Diabetes Prevention Program study, adults with prediabetes who followed a structured lifestyle program (about 150 minutes of activity a week plus modest weight loss) were 58% less likely to develop type 2 diabetes over about 3 years than the comparison group. Individual results vary, but the direction is clear: movement and food choices matter.

What improves insulin sensitivity

1. Regular aerobic activity, building toward about 150 minutes a week (Lesson 2)
2. Strength training at least twice a week, because more muscle means more places for glucose to go (Lesson 3)
3. Short walks after meals (Lesson 4)
4. Breaking up long periods of sitting (Lesson 5)
5. Balanced plates: protein, vegetables and fiber with your carbs (Lesson 6)
6. Less sugar and refined carbs (Triglycerides module, Lesson 2)
7. Sleep, stress and losing some waist fat, if you carry extra (Foundations module)

Why it matters for blood sugar

When your muscles work, they pull glucose out of your blood, partly without needing insulin. Regular activity also makes your muscles more responsive to insulin for hours to a day or more afterward. That's why consistency matters more than any single workout.

The target

US guidelines recommend at least 150 minutes a week of moderate activity, or 75 minutes of vigorous activity, or a mix (1 minute of vigorous activity counts about the same as 2 minutes of moderate). For blood sugar, it helps to spread activity across at least 3 days and avoid going more than 2 days in a row without moving.

If you're far from 150 minutes, that's fine. Any increase from where you are now helps, and the biggest benefits come from moving from "very little" to "some."

What "moderate" feels like

• Moderate: you can talk but not sing. Brisk walking, cycling on flat ground, water aerobics, dancing, yard work.
• Vigorous: you can only say a few words before pausing for breath. Jogging, hiking uphill, fast cycling, swimming laps.

Short bouts count

Older guidance said activity only counted in 10-minute blocks. Current guidelines count all moderate activity, so a 5-minute walk to the mailbox and back counts. Three 10-minute walks are as useful as one 30-minute walk.

An 8-week build-up

If a week feels too hard, repeat it. If it feels easy, move ahead. The Movement Planner suggests your starting week from your assessment answer.

If movement is difficult

Low-impact options still count: a stationary bike, water walking or aqua classes, seated exercise videos, or an arm bike. Start with 5–10 minutes of a comfortable activity on 3 days a week, and ask your provider which activities are right for you.

Why muscle matters

Muscle is where most of the sugar from a meal goes. More muscle, and muscle that's regularly used, means more capacity to clear glucose from your blood. Studies show that resistance training improves insulin sensitivity and blood sugar control, and it works even better combined with aerobic activity.

Adults gradually lose muscle with age, starting as early as their 30s, unless they use it. Strength training is the most direct way to slow or reverse that, and it also supports bone strength, balance and everyday function.

The target

Guidelines recommend muscle-strengthening activity on at least 2 days a week, working the major muscle groups: legs, hips, back, chest, shoulders, arms and core. For people managing blood sugar, 2–3 sessions on non-consecutive days is a good goal.

What counts

• Bodyweight exercises: sit-to-stands, wall or counter push-ups, glute bridges
• Resistance bands
• Dumbbells, kettlebells or gym machines
• Heavy gardening or carrying groceries can count too

Two simple ways to organize your strength days

Pick the split that suits you. Each session takes about 15–20 minutes, and core work is built in. Aim for 2 or more days a week, alternating the two sessions.

Do each move 8–12 times (planks and carries are timed or counted in steps), rest about a minute, and repeat the circuit 1–3 times. Aim to finish each set feeling like you could have done 2–3 more reps. Breathe out on the effort and don't hold your breath. Every move has an easier and a harder version in the Movement Planner.

How to progress

When 12 reps feel easy for two sessions in a row, make it a little harder: add a rep or a set, use a stronger band or heavier weight, or move to the next version of the exercise. Slow, steady progress beats soreness.

If movement is difficult

Both splits have seated versions: seated band chest press and rows, seated overhead press, seated knee extensions, supported sit-to-stands and seated core work. Start with one short session a week and check with your provider about what's safe for you.

Exercise/Physical Activity in Individuals with Type 2 Diabetes: ACSM Consensus Statement, Med Sci Sports Exerc 2022; ACSM Guidelines for Exercise Testing and Prescription.

What happens after you eat

Blood sugar typically rises after a meal and comes back down over the next couple of hours. Larger rises and slower returns are more common with insulin resistance and with meals heavy in refined carbs.

Why a short walk helps

Working muscles pull glucose from the blood. Light movement soon after eating gives that glucose somewhere to go. In one study of adults with type 2 diabetes, a 10-minute walk after each meal lowered post-meal blood sugar more than a single 30-minute walk at another time of day, with the biggest effect after dinner. Other studies found that even 2–5 minutes of light walking after eating made a difference compared with sitting.

These were mostly small, short studies, so think of this as a helpful habit, not a rule or a treatment.

How to do it

• When: start within about 30 minutes after eating.
• How long: 10 minutes is a great goal. 2–5 minutes still helps.
• How hard: easy. A relaxed stroll is enough. You shouldn't feel out of breath.
• Which meal: start with your largest meal, often dinner.

No time or space for a walk? Light chores count: washing dishes, tidying, walking around the house, climbing stairs, or marching in place.

Make it automatic

Tie it to something you already do: "When I put my plate in the sink, I put my shoes on." Invite a partner, call a friend while you walk, or walk the dog.

Sources: Reynolds AN, et al. Diabetologia 2016 (post-meal walking in type 2 diabetes); Buffey AJ, et al. Sports Medicine 2022 (meta-analysis: light activity breaks after meals); American Diabetes Association, Standards of Care in Diabetes.

Exercise and sitting are separate

Many adults sit for 8 or more hours a day. Long, unbroken sitting is linked to higher blood sugar, insulin and triglycerides, even in people who meet exercise guidelines. Your muscles are mostly "switched off" while you sit, so they use less glucose and fat.

The good news: short, frequent breaks help. In lab studies, getting up for 2–5 minutes of light walking every 20–30 minutes lowered blood sugar and insulin after meals compared with sitting the whole time. Guidance for people with diabetes recommends breaking up sitting about every 30 minutes.

The rule of thumb

Every 30–60 minutes, get up and move for 2–3 minutes. It doesn't need to be exercise. Standing, walking or light activity all count.

Ideas that fit a workday

• Stand or walk during phone calls
• Refill your water glass every hour (a built-in reason to get up)
• Use a farther restroom or take the stairs
• Do 10 sit-to-stands or calf raises between tasks
• Walk to a coworker instead of messaging
• At home: move during TV commercials or between episodes

Use reminders

Set a repeating timer on your phone or watch, or use a desk timer. Most people don't notice how long they've been sitting until a reminder tells them.

If standing is difficult

Change position and move what you comfortably can: seated marching, arm circles, shoulder rolls, ankle pumps, or standing with support if you can.

Sources: Dunstan DW, et al. Diabetes Care 2012 (breaking up prolonged sitting); Physical Activity Guidelines for Americans, 2nd edition (HHS, 2018: "move more and sit less"); American Diabetes Association, Standards of Care in Diabetes.

Not all carbs act the same

Refined carbs and sugary foods digest fast and raise blood sugar quickly. Carbs that come with fiber, like beans, lentils, whole grains, vegetables and whole fruit, digest more slowly. What you eat with your carbs matters too: protein, fiber and healthy fats slow digestion and soften the rise.

The plate template

• Half the plate: non-starchy vegetables (salad, broccoli, peppers, green beans, cauliflower)
• A quarter: protein (chicken, fish, eggs, Greek yogurt, tofu, tempeh, beans)
• A quarter: fiber-rich carbs (beans, lentils, quinoa, brown rice, sweet potato, whole fruit)
• Plus: a little healthy fat (olive oil, avocado, nuts)
• Drink: water, sparkling water, or unsweetened tea or coffee

This is the same plate the American Diabetes Association recommends. No measuring or counting is needed.

Try "carbs last"

Small studies have found that eating vegetables and protein first, and the starchy carbs at the end of the meal, led to a smaller blood sugar rise than eating the same foods in the reverse order. It's an easy experiment: same food, just a different order.

Smart swaps

Breakfast matters

Many people see their biggest blood sugar rise after a carb-heavy breakfast. A breakfast built around protein and fiber is a simple place to start.

One system, not separate problems

It's easy to think of cholesterol, triglycerides, blood sugar and blood pressure as four separate issues. In practice they're closely linked. Insulin resistance tends to raise triglycerides and lower HDL. Extra fat around the waist is linked to higher blood sugar and blood pressure. Short sleep and ongoing stress make cravings, food choices and consistency harder. When one area improves, others often follow.

That's why this program calls them cardiometabolic health: your heart, blood vessels and metabolism working together.

The foundations

The American Heart Association's "Life's Essential 8" lists the habits and measures that matter most for long-term heart and metabolic health:

The other three modules cover cholesterol, triglycerides and blood sugar. This module covers the foundations that support all of them: vegetables, sleep, stress, blood pressure and waist.

Blood pressure and waist

Blood pressure and waist size aren't on the lab panel, but both are key numbers for heart and metabolic health, and both respond to the same habits as your labs. Lesson 4 shows how to check them at home and track them over time.

If you smoke or vape

Stopping is the single biggest step you can take for your heart. You don't have to do it alone: call 1-800-QUIT-NOW (US) or talk to your provider about support that fits you.

How to use your Action Map

1. Start with the first three actions. They're ordered by your lab results first, then your habits.
2. Pick one to start this week. Add the next when it feels routine, usually after 2–3 weeks.
3. Use the Habit Tracker to check in daily. Repeat your labs as your provider suggests, often every 3–6 months, and compare.

Why vegetables matter

Vegetables bring fiber, potassium and many plant compounds, and they add volume that helps meals feel filling. Eating patterns rich in vegetables, such as the DASH and Mediterranean patterns, are linked to lower blood pressure, better cholesterol and a lower risk of heart disease. Most adults eat well under the recommended 2–3 cups a day.

The 2-meal rule

Don't aim for perfect. Aim for vegetables at two meals a day. A serving is about 1 cup raw leafy greens or ½ cup cooked or chopped vegetables. When two meals feels normal, make vegetables half your plate at one of them.

Easy ways to add them

Shortcuts that count

• Frozen vegetables are picked ripe and are just as nutritious as fresh. Keep 2–3 bags on hand.
• Batch roast once or twice a week: chop, toss in olive or avocado oil, roast at 425°F (220°C) for 20–30 minutes.
• Pre-washed and pre-cut costs more but often gets eaten instead of wasted.
• Canned tomatoes, beans and vegetables work too. Choose "no salt added" or rinse them.

Variety without overthinking

Try to include a few colors across the week: dark leafy greens, red and orange (tomatoes, peppers, carrots, sweet potatoes), cruciferous (broccoli, cauliflower, cabbage, Brussels sprouts) and beans or lentils. Starchy vegetables like potatoes and corn count, but pair them with non-starchy ones.

Why sleep matters for your metabolism

Adults do best with 7–9 hours of sleep a night. Regularly getting less than 7 is linked to higher blood sugar, more insulin resistance, higher blood pressure and weight gain. In short-term studies, cutting sleep for even a few nights made people less sensitive to insulin and hungrier the next day, especially for sweet and high-calorie foods. Broken, restless sleep has similar effects, even when time in bed looks fine.

That's why sleep is in this program: it makes every other change (food, movement, consistency) easier.

Part 1: Getting enough hours

1. Fix your wake time. Pick a wake time you can keep on most days, including weekends (within about an hour).
2. Count back 7½ hours. That's your target "in bed" time. Example: wake at 6:00 → in bed by 10:30.
3. Move bedtime earlier by 15–30 minutes each week until you reach your target. Big jumps rarely stick.
4. Set a wind-down alarm 30–60 minutes before your target bedtime.

If you work shifts or care for others, protect the sleep you can: a dark, quiet room (eye mask, earplugs or white noise), the same routine before every sleep, and a short nap when you can.

Part 2: Sleeping more deeply

During the day

• Get outdoor light in the morning, ideally within an hour of waking, for 10+ minutes. It helps set your body clock.
• Move during the day. Regular activity is linked to better sleep (just finish hard workouts a couple of hours before bed if they keep you up).
• Stop caffeine at least 6–8 hours before bed.
• If you drink alcohol, keep it earlier and lighter. Alcohol can help you fall asleep but tends to break up sleep later in the night.
• Finish larger meals 2–3 hours before bed if late eating gives you heartburn or keeps you up.

Your bedroom

A 30-minute wind-down. Pick 2–3 that you enjoy and do them in the same order each night: dim the lights, a warm shower, light stretching, reading a paper book, writing tomorrow's to-do list, or slow breathing (Lesson 5). The routine itself becomes a signal to your body that sleep is coming.

If you can't fall back asleep. If you've been awake for what feels like 20 minutes, get up, go somewhere dim, and do something calm until you feel sleepy, then return to bed. Avoid checking the clock. This is part of cognitive behavioral therapy for insomnia (CBT-I), the recommended first treatment for long-term insomnia.

If you sleep more than 9 hours

Some people simply need more sleep. If you regularly sleep more than 9 hours and still feel tired, or your need for sleep has recently increased, mention it to your provider. It can be worth checking things like sleep quality, mood, thyroid or medications.

Why these two numbers matter

High blood pressure often has no symptoms, yet over time it strains the heart, blood vessels and kidneys. It's one of the biggest drivers of heart disease and stroke. Waist size reflects fat stored around the middle, which is closely linked to insulin resistance, higher triglycerides, lower HDL and higher blood pressure. Neither number shows up on a blood test, so you track them yourself.

Blood pressure: what the numbers mean

One reading doesn't define you. Blood pressure changes through the day, and it's often higher at a clinic. What matters is your typical average over several days. This lesson gives education only. Your provider diagnoses high blood pressure.

How to take an accurate reading at home

1. Use a validated upper-arm cuff in the right size for your arm (check the packaging or validatebp.org). Wrist and finger devices are less reliable.
2. For 30 minutes before: no caffeine, exercise or smoking. Empty your bladder.
3. Sit quietly for 5 minutes with your back supported, feet flat and legs uncrossed.
4. Rest your arm on a table at heart level, with the cuff on bare skin. Don't talk.
5. Take 2 readings, 1 minute apart, in the morning and evening for a week, and write them down. Bring the log to your provider.

No cuff yet? Many pharmacies have free machines. Use the same one each time.

Habits that support healthy blood pressure

• Eat more vegetables, fruit, beans and whole grains (the DASH pattern). That's Lesson 2 and the Grocery Guide.
• Cut back on sodium. Most of it comes from packaged, restaurant and processed foods, not the salt shaker. The general goal is under 2,300 mg a day, and less is often better. Use the sodium line on the Grocery Guide's label page.
• Move most days. Both walking and strength training help (Blood Sugar & Insulin module).
• If you drink alcohol, keep it moderate (Triglycerides module).
• Protect your sleep and add a daily stress reset (Lessons 3 and 5).
• Losing waist size often brings blood pressure down too.

Waist: how to measure

1. Stand up straight and breathe out normally.
2. Wrap a soft tape measure around your bare waist, just above the top of your hip bones (usually near the belly button).
3. Keep it snug but not pressing into the skin, and level all the way around.
4. Measure at the same time of day (morning is easiest) every 2–4 weeks, and log it in the app.

Your waist can shrink even when the scale barely moves, especially as you build strength. That's progress.

Weight and BMI: tracking, not judging

If you enter your height and weight, the app shows your BMI with its standard category (underweight, healthy weight, overweight or obesity) so you can watch the trend. If you're of South Asian, East Asian or Southeast Asian background, check "Use Asian BMI cutoffs": health risks start at a lower BMI, so the categories shift (healthy weight 18.5–22.9, overweight 23–24.9, obesity 25+). BMI doesn't tell you about muscle, where fat is stored or your health on its own, so it never changes your Action Map. Your waist and how you feel are often more useful signs of progress.

How stress affects your health

When you're under pressure, your body releases stress hormones such as adrenaline and cortisol. In short bursts that's helpful. When stress stays high for weeks or months, it's linked to higher blood pressure, poorer sleep, more cravings for sugary and high-fat foods, less activity and a harder time sticking to plans. The American Heart Association recognizes ongoing stress, depression and anxiety as factors that affect heart health.

Your assessment asked how stressed you feel. That answer can't measure your cortisol or any hormone level, and this program doesn't diagnose hormone problems. It simply tells us stress management is worth building into your plan.

This program doesn't include cortisol testing. If you want your cortisol tested, we test it in our Doctor-Developed Metabolic Reset program.

Three 5-minute resets

Make it automatic

Attach your reset to something you already do every day: after your morning coffee, when you park at work, after lunch, or right before your wind-down. Same time, same cue. Then check it off in your Habit Tracker.

Other things that help

• Regular movement, which is one of the most reliable stress relievers
• Time with people you trust: a call, a walk with a friend, a shared meal
• Protecting sleep (Lesson 3). Stress and poor sleep feed each other.
• Fewer "always on" moments: turn off non-essential notifications and set times to check email and news
