Six rules, one plate at a time
Not a meal plan. Meal plans are somebody else's week, and they fail the first time life moves. This is a set of rules you can apply to any kitchen, any cuisine and any schedule — each one graded by how strong the evidence behind it actually is.
- Strong meta-analysis or pooled trials
- Moderate one good trial, or consistent smaller work
- Weak tiny sample or surrogate outcome
Set the protein floor, then stop thinking about protein
Protein is the only macronutrient with a hard number worth defending. Pooled across 49 studies and 1,863 trainees, gains in lean mass stopped improving once total intake passed roughly 1.6 g per kilogram of bodyweight per day. More than that is not harmful — it is simply not the thing holding you back.
Hit it in servings, not in one heroic meal. Around 0.4 g/kg per sitting is the practical target, which means a real protein serving at every meal you eat: eggs, fish, poultry, dairy, tofu, legumes plus grains. On three meals a day that is a larger portion each time than most people picture.
One macro lane per meal — carbs or fat, not both
Pick a lane and build the plate inside it. A carb-dominant meal is rice, potato, pasta, fruit or bread with lean protein and vegetables, and almost no added fat. A fat-dominant meal is olive oil, nuts, avocado, whole eggs, oily fish and vegetables, with almost no starch. Protein is in both. Vegetables are in both.
The folk explanation for this rule — that fat 'coats' the sugar and wrecks digestion — is not true, and it is worth saying so plainly. The rule works for two much better reasons. First, energy density: we eat a roughly constant weight of food, and separating fat from starch takes a plate from about 2 kcal per gram down to about 1.2 without shrinking it. Second, reward: people will pay more for foods that combine fat and carbohydrate than for equally liked, equally caloric foods containing only one of the two, with a supra-additive response in the reward circuitry. Fat plus starch is the signature of everything engineered to be overeaten.
This is a portion-control heuristic, not biochemistry. Trace fat in a carb meal — 5 to 15 g — is irrelevant. The lane you are avoiding is the deliberate one: butter on the potato, cream in the pasta, cheese on the bread, oil in the fried rice.
Fuel for the work required
Carbohydrate is not a fixed daily allowance. It should move with the week, sitting heaviest around the sessions that need it and lightest on the days that do not. On a four-lift week, that means the lifting days and the aerobic day carry the starch, while the recovery flow and the rest day carry less of it.
Placement matters more than total on training days: the meal before the session and the meal after it are where the starch belongs. If training happens before the first meal of the day, then the previous evening's carb meal is the pre-workout meal — which is the whole argument for eating your largest starch serving at dinner rather than treating it as an indulgence.
Fat has a floor, not a target
Because the lane rule keeps fat out of most meals, fat is the macronutrient most likely to end up accidentally near zero. That is a mistake. Across six intervention studies in 206 men, low-fat diets measurably lowered total and free testosterone compared with higher-fat diets. Small studies, so treat it as a caution rather than a law — but the direction is not one to volunteer for.
Set roughly 0.6 to 0.8 g/kg/day as a floor and let it come from real food: egg yolks, oily fish, olive oil, nuts. Concentrate it in the fat-lane meals, where it is not competing with starch.
Timing is the smallest lever in the room
Meal frequency does not decide body composition. Across 15 studies, eating more often was not significantly associated with weight change, and the apparent body-composition benefit vanished once a single outlying study was removed. Training fasted does not accelerate fat loss either: when calories and training volume are matched, fasted and fed groups change the same amount.
So build the day around your life. If your first meal lands at noon, eat three larger meals from noon. If you train before breakfast, that is a schedule, not a strategy — and the only real cost is output in the last third of a hard session, which a small carbohydrate drink during the session fixes.
Drink to a colour, not to a number
Litre targets are guesswork applied to a body that already has a gauge. Urine colour tracks urine specific gravity and osmolality closely enough for field use: aim for pale straw across the day. Clear is not the goal — clear usually means you are drinking past what you need and diluting sodium for no benefit.
The practical version: a glass on waking, a glass before each meal, and water alongside training. If a session is long, hot or sweaty, salt the food afterwards rather than avoiding salt.
Scaled to bodyweight, because grams are not universal
Protein is bodyweight × 1.75 g. Fat is bodyweight × 0.6 to 0.8 g as a floor. Carbohydrate is the flexible one: the low end of the range is a rest day, the high end is a hard training day. Calories are what falls out of those three, not a target to hit.
| Bodyweight | Protein / day | Fat floor / day | Carbohydrate range | Approx. calories |
|---|---|---|---|---|
| 60 kg | 105 g | 36–48 g | 160–240 g | ~1,800 |
| 70 kg | 120 g | 42–56 g | 185–280 g | ~2,100 |
| 80 kg | 140 g | 48–64 g | 210–320 g | ~2,400 |
| 90 kg | 155 g | 54–72 g | 235–360 g | ~2,700 |
| 100 kg | 175 g | 60–80 g | 260–400 g | ~3,000 |
These are arithmetic from the per-kilogram rules above, rounded — not measured outcomes. If you are carrying a lot of excess bodyweight, scale protein to a target weight rather than the number on the scale today.
Two days, both legal
The lane column is the whole trick: no day has two fat-lane meals sitting next to a big starch serving. Nothing here depends on the clock times — only on where the session sits.
A — Trains before the first meal
| When | What | Lane |
|---|---|---|
| On waking | Water. Coffee or tea if you drink it | — |
| During the session | Water; on hard days, 30–50 g carbohydrate sipped through it | Carb |
| Meal 1 — after training | Whole grain or starch, lean protein serving, vegetables. Minimal added fat | Carb |
| Meal 2 — afternoon | Protein serving, large vegetables or salad, legumes. Fat allowed here | Fat |
| Meal 3 — evening | Largest starch serving of the day, protein serving, vegetables, low-fat sauce | Carb |
B — Trains after work
| When | What | Lane |
|---|---|---|
| Meal 1 — morning | Whole eggs, avocado or nuts, vegetables or berries. Little to no starch | Fat |
| Meal 2 — midday | Protein serving, large salad, legumes, olive oil | Fat |
| Pre-session | Fruit, rice cakes or a small starch serving, 30–60 g carbohydrate | Carb |
| Session | Water | — |
| Meal 3 — after training | Largest starch serving of the day, protein serving, vegetables, minimal added fat | Carb |
What this page will not tell you
Most nutrition writing sells certainty. Here is the certainty this page declines to sell, and why — because knowing which claims are false is worth as much as the rules themselves.
| The claim | Why it is not here |
|---|---|
| “Your metabolism is damaged and needs years to heal.” | Metabolic adaptation to dieting is real and modest. Multi-year 'damage' requiring a specific diet to repair is a sales device, not a finding. |
| “Calories don't matter if the food is clean.” | Energy balance is not optional. Food quality changes how many calories you eat before you feel full, which is exactly why the lane rule works. |
| “Sugar eaten alone cannot be stored as fat.” | It can. De novo lipogenesis is slow, but surplus energy is stored regardless of which macronutrient carried it in. |
| “You must eat protein within 30 minutes of training.” | The anabolic window is hours wide for anyone who has eaten that day. Daily total and per-meal dose are the levers. |
| “Clear urine ten times a day is the hydration target.” | That is overdrinking. Pale straw is the target, and diluting sodium while training hard is a bad trade. |
| “This is the one correct way to eat.” | It is a defensible default for a lifelong trainee. Medical conditions, medications, pregnancy and eating-disorder history all outrank it. |
The four that come up first
Do I have to separate carbs and fat at every single meal?
No. It is a default, not a commandment. Trace fat in a carb meal is irrelevant — the lane you are avoiding is the deliberate one: butter on the potato, cream in the pasta, oil in the fried rice. Aim to keep added fat under roughly 12 g in a carb-dominant meal.
Is this a weight-loss diet?
It is a structure that makes portion control happen without counting, so it works in a deficit, at maintenance, or in a surplus. The protein floor and the fat floor stay the same in all three. Only the size of the starch servings changes.
What if I train before my first meal?
Then the previous evening's carb meal is your pre-workout meal, which is the strongest argument for backloading starch to dinner. On hard sessions, sip 30–50 g of carbohydrate during the session; on easy ones, don't bother.
Is a vegetarian or vegan version of this workable?
Yes, with one caveat: legumes and grains are carb-and-protein foods, and nuts and seeds are fat-and-protein foods, so vegetarians hit the protein floor most easily in the carb lane. Keep the fat-lane meals built on tofu, tempeh, seitan or dairy rather than on nuts alone.
Read this part
This is not medical advice, and it is not written by a dietitian or a certified trainer. It is a training-focused reading of published research, with the weak evidence labelled weak. If you take medication, are pregnant, manage a metabolic or kidney condition, or have any history of disordered eating, a qualified professional outranks every rule on this page. Bloodwork before a big change and twelve weeks after is the honest way to find out whether it worked for you.
