Meal Macro Split Calculator

Take your daily macros and turn them into meals. Even splits are simplest; weighting one meal larger suits people who prefer a bigger dinner or more carbohydrate around training.

Does the split matter?

Much less than the daily totals. The hierarchy is:

  1. Total calories — determines whether you gain or lose.
  2. Total protein — determines how much of that change is muscle.
  3. Food quality and fibre — determines how you feel and how easy it is.
  4. Distribution and timing — a small optimisation.

So use this to make your day practical, not to optimise. If an even split is easier to follow, that beats a theoretically better one you find annoying.

When weighting a meal is genuinely useful

  • Carbohydrate around training. Worth doing for sessions over 90 minutes, two sessions in a day, or endurance work. For a 45-minute lift, daily total is what matters.
  • A larger dinner if that is when you actually want to eat. Late eating does not cause fat gain — the association with unplanned eating is behavioural, not metabolic.
  • Protein before bed — 30–40 g, moved into that slot rather than added.
  • Lower fat and fibre pre-training, for comfort rather than performance.

Common questions

Should I eat the same macros at every meal?

An even split is simple and works. Weighting is a preference, not an optimisation.

Should I eat more carbs around training?

For long or repeated sessions, yes. For a normal 45-minute lift, daily total matters more.

Does eating late cause fat gain?

No. Late eating correlates with unplanned calories, which is a different thing.

How many meals is best?

Three to four is a reasonable default. Two works. Six is not better.
