The HeartSync portion guide
Portion control
How much to put on the plate, and how paid personalisation begins.
A plain-language portion guide the household reads before signing in — the plate method and the hand-cup framework, serving examples across proteins, vegetables, carbohydrates, fats, snacks, and beverages, plus label-reading and mindful-eating tips and the mistakes a household most often skips.
Educational only: exact serving sizes, condition-tuned portions, and household drafts live in your private plan at Member Nutrition once you’re signed in.

The right rail jumps to the section you want. The personal plan replaces this once you’re inside the rhythm.
Section 01 · The methods
Portion methods — the plate, the hand, the read.
Three heuristics carry most of the work — the half/quarter/quarter plate rule, the palm/fist/cupped-hand framework, and a calm read of the label. Calorie numbers sit on these as a population read, not a household prescription.
Three small heuristics cover most of a household’s portion decisions without a kitchen scale or a chart on the wall. The plate method — half vegetables, a quarter protein, a quarter slow carbohydrate — is the first. The hand-cup framework — a palm of protein, a fist of vegetables, a cupped hand of slow carbohydrate, a thumb of fat — is the second, sized automatically to the body that is eating. The label read is the third — serving size, percent daily value, ingredient order. Stacked together they describe the day the body already keeps.
The calorie numbers that show up on the label and in the population read — around 1,800–3,400 kcalacross sedentary, moderate, and active adult days — describe populations, not the household in front of you. They are useful as a check that the plate is in the same neighbourhood as the body’s week, not as a calorie target to memorise. For the precise intake and the condition-tuned plate sizes the body actually keeps, the food plan guide carries the detailed read, and the calorie-context section sits one click in. The portions section of the same guide is the inline partner to this page.
Section 02 · Anatomy
The plate and the hand — the household’s two measuring tools.
The plate method sets the proportions: half vegetables, a quarter protein, a quarter slow carbohydrate. The hand-cup framework sizes each one to the body that is eating. Together they cover most of the day without a kitchen scale.
The plate method is the simplest place to start. Half the plate is vegetables — fibrous and colourful, raw or cooked depending on the day. A quarter is protein — animal or plant, sized to the cook and the household. The final quarter is a slow carbohydrate — whole grains, legumes, root vegetables, oats, or the slower-cooking rices. A small thumb of fat rides alongside (olive oil, avocado, nuts). The plate is the geometry; the hand sizes it.
The hand-cup framework sits on top of the plate method and sizes each portion to the body that is eating. A palm of proteinat each cooked meal, including its depth — the thickness of the palm, not just the footprint. A fist of vegetables, with two fists on the larger meal of the day if the day is heavy. A cupped hand of slow carbohydrate — the hand scooped, not flattened — smaller on the evening meal. A thumb of fat for oil and spreads. A household that lifts more, walks more, runs after children, or trains eats more; a household recovering from a heavy week eats less. The pattern matches the body, not the chart.
Per-meal and bridge adjustments sit on top. A heavier-training day sees a second cupped hand of slow carbohydrate alongside the midday meal, an extra palm of protein, and an extra fruit at the mid-afternoon bridge. A lower-sensitivity day flattens the cooked vegetables, holds the carbohydrates on the slower side (rice, oats), and skips the raw salads. Both patterns are described in more detail in the meal-structure section of the food plan guide.
Section 03 · Proteins
Protein portions — palms, hands, and the family the day sees.
Animal and plant sources both qualify. The portion is a palm — sized to the cook, paired with a fibre read on the side. Gram counts and condition-tuned servings belong in the private plan.
Protein portions are the easiest sizing in the day. A palm at each cooked meal sets the animal and plant sources the household rotates through — red meat, poultry, fish, shellfish, eggs, legumes, tofu and tempeh, full-fat dairy. The palm sizes it to the individual, not the household, so a child’s palm and a parent’s palm sit side by side without a kitchen scale at all.
A practical read on raw versus cooked weight matters: a raw portion shrinks — typically by around 20–30 percent — once it cooks. The palm on the cooked plate is what the household actually eats; the raw portions at the shop sit a touch larger. Both red and white fish cook down more than red meat; shellfish and eggs shrink the least. Dairy portions sit slightly smaller than the palm because they are denser: a palm of yoghurt is about the same calories as a slightly larger palm of fish.
Gram counts, condition-tuned plate sizes (keto, renal, post-surgical, paediatric), and the protein floor per body-makeup are all in the private plan at Member Nutrition once the household has signed in. The hand heuristic above covers the 80 percent of days the body already eats well by instinct.
Red meat (beef, lamb, pork)A palm — about the thickness and footprint of an open palm.
A palm of red meat at one of the cooked meals of the day, willing to share with a plant protein earlier or later.
Raw shrinks roughly a quarter once cooked. The cooked palm is what the household eats.
Poultry (chicken, turkey)A palm — cooked weight, boneless and skinless.
A palm of poultry is a versatile cooked-meal protein, paired with the half-plate of vegetables and the cupped hand of slow carbohydrate.
A thigh without skin is similar to a chicken-breast palm in calorie load. The household reads whichever it cooks that day.
Fish (white fish, salmon, sardines)A palm — cooked weight, denser for oily fish and softer for white fish.
A palm of fish at one cooked meal; oily fish once or twice a week as the fat portion rolls in.
Raw shrinks by a quarter to a third. The oven or pan reading the cooked fillet is what the day sees.
Shellfish (shrimp, mussels, clams, scallops)A palm or a slightly larger fist, cooked and shelled.
A cooked shellfish portion sits within the same palm heuristic as the white fish the household rotates through.
Shellfish shrinks less than finfish once cooked — the palm at the table is closer to the palm at the shop.
Eggs (whole, yolks, whites)Two eggs per portion (roughly a palm of mixed egg); three eggs on a heavier-training day.
A two-egg portion rides breakfast or a midday cooked meal; yolks ride alongside when the household eats the whole egg.
A two-egg portion is roughly 100–140 kcal depending on size; the body’s morning read on satiety holds best at two eggs plus a fibre side.
Legumes (lentils, chickpeas, beans)A palm or a slightly larger fist, cooked weight.
Legumes qualify as protein or as slow carbohydrate depending on the meal — a smaller palm as a protein, a cupped hand as the carbohydrate side.
Canned legumes rinse clean of the sodium the day does not need; cooked-from-dry carries the gentler read the gut asks for.
Tofu and tempehA palm, sliced.
A palm of tofu or tempeh paired with the half plate of vegetables and a slow carbohydrate side; tempeh is denser than tofu at the same volume.
Tempeh is closer to a meat palm in calorie load; silken tofu is closer to half. The household reads whichever it eats.
Full-fat dairy (Greek yoghurt, cottage cheese, hard cheese)A slightly smaller palm than animal protein — denser at the same volume.
A small pot of yoghurt, a fist of cottage cheese, or a thumb-block of hard cheese is the typical portion; yoghurt-and-fruit rides the bridge windows.
Hard cheese adds calories quickly — a thumb-sized block is the typical portion. Yoghurt and cottage cheese sit gentler.
Section 04 · Vegetables
Vegetable portions — the half plate, the fist, the cooked-vs-raw note.
Half the plate is vegetables. Fibrous and colourful forms dominate, with cooked volume flattened on sensitive days. The fibre read is shared with the conditions library.
Half the plate, every cooked meal, is the rule of thumb. Within that half, fibrous and colourful vegetables — leafy greens, cruciferous, allium, fruiting vegetables, the rainbow roots — dominate. A fist is the smallest serving; two fists ride the larger meal of the day on a heavier-training week. Soups and stews count: a fist of vegetables cooked down is still a fist of vegetables once the water is gone.
Cooked versus raw matter for volume. A fist of cooked leafy greens is about three fists raw. A fist of cooked cruciferous is about two fists raw. On a lower-sensitivity day (gut, autoimmune or general inflammation), the cooked volume is what the household reads, not the raw salad that would feel the same in the hand. The same read lives in the gut-health notes for households flagging that pattern — raw salads get ordered later in the meal, and the cooked side sits at the front of the plate.
The conditions library carries the per-condition fibre ordering the day asks for. The broader conditions read sits alongside, and the private plan encodes it once the household flags something.
Leafy greens (spinach, kale, chard, rocket)A fist raw, or three fists raw to one fist cooked.
A fist of leafy greens at each cooked meal; two fists on the larger meal of the day.
Cooked volume shrinks to about a third of raw. Lower-sensitivity days read the cooked volume, not the raw hand-cup.
Cruciferous (broccoli, cauliflower, cabbage, Brussels sprouts)A fist cooked, two fists raw; the cooked portion is the typical cooked-meal read.
A fist of cooked cruciferous rides the cooked meal; raw slaw rides the bridge where the household asks for it.
On a flagged gut-health day the cooked ordering has broccoli at the front of the plate and the raw slaw later or smaller.
Allium (onion, garlic, leek, scallion)A fist or smaller — an aromatic support rather than a main vegetable.
A fist or smaller of allium sits across most cooked meals of the day; it builds the flavour base without competing with the vegetables.
Roasted allium sits gentler on the gut than raw — the household reads the form it eats.
Fruiting vegetables (tomato, courgette, aubergine, pepper)A fist cooked.
A fist of fruiting vegetables rides cooked meals; raw tomato and pepper ride the bridge windows.
Cooked tomato is denser in the day’s available lycopene than raw; both count as a serving.
Root vegetables (carrot, beet, sweet potato, potato)A fist cooked.
Root vegetables straddle the cooked vegetable and the slow carbohydrate; the cupped hand is what the day reads for the carbohydrate side.
A household that is flagging metabolic patterns reads the root as a carbohydrate rather than a vegetable on the plate.
Section 05 · Carbohydrates
Slow-carbohydrate portions — a cupped hand at each cooked meal.
A cupped hand of slow carbohydrate at each cooked meal. Whole grains, legumes, root vegetables, oats, slower-cooking rices. Fruit rides its own window. Glycaemic-load notes belong to the metabolic read.
Carbohydrate — the carbohydrate quarter of the plate — is sized to a cupped hand at each cooked meal, smaller on the evening meal than on the midday or breakfast meal. The slow forms the day keeps — whole grains, legumes, root vegetables, oats, the slower-cooking rices — are the default; the fast forms (white bread, white rice, sugar-forward breakfasts) are a less frequent thing.
Legumes straddle the two groups neatly: they qualify as a protein portion at a smaller palm or as a carbohydrate portion at a cupped hand, depending on what the day needs. Together with tofu and tempeh they round out the plant-protein side the household already sees. Root vegetables — potato, sweet potato, beet, carrot — sit with the slower-cooking grains for portion purposes, even though they are vegetables first.
Fruit rides a separate window from the cooked meals. A piece of whole fruit, a cupped hand of berries, or a small portion of stewed fruit is the typical bridge; dried fruit is denser and counts slightly more (a cupped hand of dried is closer to three cupped hands of whole); juice is the densest form and is best treated as an occasional bridge rather than a daily default. For households flagging metabolic flags, the carbohydrate timing and the slow-versus-fast split is the lever; the per-day gram count moves into the private plan once the household is signed in. The nutrition guidelines carry the broader eating-right read.
Whole grains (brown rice, wholewheat, buckwheat, barley)A cupped hand — cooked weight.
A cupped hand of whole grain sits at each cooked meal; smaller at the evening meal, larger or doubled at the heavier-training midday.
Cooked volume is roughly three times the dry volume. The cupped hand reads the cooked grain at the plate.
Legumes (lentils, chickpeas, beans) — the carbohydrate readA cupped hand of cooked legumes when the legume is the carbohydrate side of the plate.
Where the household eats legumes as the slow carbohydrate, the cupped hand replaces the grain; the protein side moves with the vegetables.
A house that eats legumes twice a day often sees two cupped hands across the cooked meals, one as protein and one as carbohydrate.
Root vegetables — the carbohydrate readA cupped hand of cooked root.
Where the plate is grain-light, root vegetables sit in the cupped-hand carbohydrate slot alongside a smaller grain or instead of one.
A heavy-training day reads the root as the second cupped hand of slow carbohydrate; a sedentary day reads it instead of the grain.
Oats (rolled, steel-cut)A cupped hand of cooked porridge — roughly a quarter-cup dry.
A typical breakfast portion; steel-cut holds satiety longer and reads well at the bridge windows if the morning meal arrives later.
Rolled oats are the family default; steel-cut shifts the morning energy curve a touch later.
Slower-cooking rices (long-grain white, basmati, sushi rice)A cupped hand of cooked rice.
White rice sits in the cupped-hand slot but reads closer to a slow carbohydrate on cooler or heavier-training days.
Cooled-rice starch shifts in the gut; a homemade rice bowl the night before still sits within the cupped hand at lunch.
Fruit portions (whole, dried, juice)One piece of whole fruit; a cupped hand of berries; a cupped hand of dried fruit is denser, two cupped hands of whole.
A whole-fruit portion sits at the bridge window; juice rides occasional rather than daily.
The household that flags metabolic patterns keeps fruit paired with a protein or fat bridge so the sugar curve holds.
Section 06 · Fats
Fat portions — thumb pour, thumb spread, palm of oily fish.
A thumb of fat per cooked meal. Cooking oils, nut butters, nuts and seeds, avocado, fatty fish, and the occasional yolk. Fat-soluble vitamins ride alongside the fat portion.
Fat portions are small and easy to overshoot. A thumb-sized pour of oil at each cooked meal — around a tablespoon — is the default. The same thumb for a spread of nut butter. A small cupped hand of nuts and seeds as a bridge. Half an avocado as the “fat of the meal” if the meal is otherwise lean. A palm of oily fish (salmon, mackerel, sardines, herring) instead of a palm of white fish once or twice a week. Yolks ride the meal when the household eats the whole egg.
Olive oil and the nut oils (walnut, hazelnut, pistachio) ride cold applications — dressings, drizzles, the finishing pour — rather than the high-heat cook. The high-heat cook belongs to the more stable oils (olive, avocado). Both kinds still count toward the thumb measurement for the meal.
Fat portions matter because fat-soluble vitamins — A, D, E, K — absorb alongside the fat on the plate. A meal that is fat-light misses that absorption; a meal that is fat-heavy overshoots the calorie range the body already keeps. The space between is small and the eye reads it well. For households keeping caffeine in its morning window (which the hydration section of the food plan names), the fat-cooked meal sits well outside the caffeine window — not because they conflict, but because both ride the morning and one will quietly crowd the other.
Cooking oils (olive, avocado, stable nut oils)A thumb pour — roughly a tablespoon — at each cooked meal.
A small thumb of oil is the cook’s baseline; the higher-heat cook uses the stable oils, the cold applications use the finishing oils.
Family-sized portions read bigger than they are meant to — the thumb is the measurement, not the visible pour.
Olive and nut oils (walnut, hazelnut, pistachio)A thumb pour — same measurement as the cooking oil, but in the cold application. The dressing, drizzle, or finishing overlay.
A thumb of cold-application oil sits at the table on a cooked meal, dressed just before serving.
The flavour load is denser than the cooking-oil thumb at the same volume; one thumb is the same calorie load either way.
Nut butters (almond, peanut, hazelnut, cashew)A thumb spread on bread, oats, or fruit; the same thumb a couple of times across the day as the bridge rides.
A small thumb of nut butter on oats is a typical breakfast allowance; the same thumb on a fruit bridge is a typical midday allowance.
Two thumbs a day is the upper-end thumb count before the day’s fat load overshoots.
Nuts and seedsA small cupped hand — about 25–30 grams.
A small cupped hand of nuts or seeds at one of the bridge windows; almonds, walnuts, pumpkin seeds, and sunflower seeds are all typical.
Two cupped hands in a day is the typical upper-end; the household that hits the upper end typically pairs this bridge with a lighter cooked meal.
AvocadoHalf an avocado — the typical portion.
Half an avocado rides a cooked meal or a bridge where the household has skipped the nut-butter thumb at that window.
A whole avocado is a heavier fat load than the typical day asks for; half sits at the front of the read.
Oily fish (salmon, mackerel, sardines, herring)A palm of cooked oily fish once or twice a week.
A palm of oily fish replaces a palm of white fish or a palm of red meat on the days the household eats the oily form.
The oily fish already carries the day’s fat load at the protein side — the thumb of oil at that meal is smaller or absent.
Egg yolksA yolk per whole egg.
Where the household eats the whole egg, a yolk-by-yolk count sets the fat load at breakfast; egg-white-only reads lower.
A two-egg whole-egg portion carries roughly a thumb of fat across the meal.
Section 07 · Bridges & drinks
Snacks and beverages — bridges sized for the day, water for the day.
Bridges hold the day’s energy curve steady — small cupped hands of nuts, fruit, yoghurt, a dark-chocolate square. Water is the daily drink; caffeine rides the morning; alcohol is a separate post, not a daily default.
Bridges — the small windows between meals — are not snacks the day negotiates for; they are the small fix the day uses to hold its energy curve steady. A small cupped hand of nuts or seeds; a piece of whole fruit; a small portion of yoghurt or kefir; a square of dark chocolate (70 percent or higher) if the day asks for it. The bridge is sized so it does not displace the next cooked meal — small enough that mid-meal satiety still arrives on schedule.
Water is the daily drink. A practical range sits around 1.6–2.4 litres across the adult day, more on a heavier-movement or warmer day, less if the household eats its hydration in soups, stews, fruit and vegetables. A small glass at each transition between meals is the simplest cue. Sweetened drinks do not qualify as hydration; the sugar load they ship offsets the water balance the day otherwise keeps.
Caffeine rides its morning window — before noon for most households, before the early afternoon for the rest. The Supplement Timing Guide carries the spacing from the afternoon supplement doses, and the broader water-versus-caffeine read lives on the hydration section of the food plan. Alcohol is not a daily default. When it arrives, it is a thing on its own evening, with the wind-down runway the night still keeps and the water pour the body already expects.
A small cupped hand of nuts or seedsA small cupped hand — about 25–30 grams.
A typical bridge between the midday meal and the evening meal, when the day’s gap is longer than four hours.
A smaller bridge rides closer to the next meal; a larger bridge sits at a midpoint.
A piece of whole fruit, or a cupped hand of berriesOne piece of whole fruit; a cupped hand of berries.
A typical mid-morning or mid-afternoon bridge; whole fruit rides a gentler sugar curve than juice.
The fruit bridge sometimes pairs with a thumb of nut butter or a small pot of yoghurt for households flagging metabolic patterns.
A small pot of yoghurt or kefirA small pot — 125 to 175 grams.
A typical bridge where the day’s portion of dairy is light; full-fat yoghurt reads gentler on the satiety curve than low-fat sweetened forms.
Sweetened yoghurts are a less frequent bridge — the sugar load offsets the protein read.
A square of dark chocolateOne to two squares — 70 percent cocoa or higher.
A bridge that arrives when the day’s gap is leaving the household a little flat. 70 percent or higher reads as the slow-burn form.
Two squares are the upper end; milk chocolate rides lower on the cocoa and the slower curve the day expects.
WaterA 1.6–2.4-litre day; a small glass at each meal transition.
The default drink of the day. Cooler water reads gentler on the morning stomach; warmer water sits well at the evening wind-down.
Tap water reads fine for most households; filtered or spring water sits gentler where the household has the option.
Caffeine (coffee, tea, matcha)One to two cups in the morning window — before noon, before the early afternoon.
A morning-window drink. The Supplement Timing Guide spaces afternoon supplements away from caffeine.
Caffeine past mid-afternoon rides the sleep entry the night still keeps — the day does not recover it overnight.
AlcoholA small glass, on the day the household has it; not a daily default.
Not a daily default. When alcohol arrives, it is a thing on its own evening, with the wind-down runway the night still keeps.
The household that is flagging liver, sleep, or hormone-balance patterns keeps alcohol at a lower frequency still.
Sweetened drinks (juice, soda, sweetened coffee or tea)Not a daily default — an occasional bridge at most.
Sweetened drinks offset the water balance the day otherwise keeps; the sugar load ships alongside the liquid.
A small occasional glass is the upper-end allowance in most households; daily sweetened drinks are a less frequent pattern.
Section 08 · Labels, pace, mistakes
Label-reading, mindful eating, and the common mistakes a household skips.
A short read of the label — serving size, percent daily value, ingredient order, sugar aliases. A short read of mealtime pace. A short list of the mistakes a household most often skips.
Label reading. Three numbers carry most of the work. Serving sizesits at the top of the panel and is what the rest of the label is sized to; the household reads the portion in serving-size units, not in “the bag.” Percent daily value is a population read against a 2,000-kcal adult day, useful for comparing foods against each other than against a target. Ingredient listis front-loaded in order of predominance; the first three ingredients are most of the food. Sugar has a long list of aliases (sucrose, fructose, glucose, maltose, syrup, nectar, concentrate, juice); “natural” does not mean “low”; and added fats ride in the ingredient list even when the nutrition panel reads lower than expected. Fibre and protein at a glance matter most once they are on the panel — both belong at the top of the read.
Mindful eating. Pace is the second lever. A short pause before the meal — ten seconds, the plate on the table, the food in front of the household — sets the satiety rhythm up. The meal without screens reads better than a meal with them. The first forkful arrives slowly. A mid-meal satiety check — a half-second pause around the middle of the meal, the question “how full am I, really” — closes the day’s overshoot before it lands. None of this is a meditation; it is a small fix the body already knows.
Common mistakes. A short list of the ones a household most often skips: estimating serving size by eye rather than measuring once and learning the cup; eating from the bag (the bag does not stop when the household’s portion has stopped); drinking calories in juice, sweetened coffee, alcohol, or soda; stacking fat-heavy portions (oil plus nuts plus cheese plus avocado at one meal); skipping the bridge and overeating at the next cooked meal; overcompensating when a label reads “low-fat” by adding more elsewhere; fruit juice read as a fruit equivalent (it is not); and “natural” read as “more is better” (it usually means the same calories the household already eats). For the broader question set, the common questions page carries the household-side answers.
