Macro Calculator

Estimate daily calorie and macro targets from your stats, then see them front-loaded across your meals to match how your body handles carbs, protein, and fat at different times of day.

Per-meal breakdown

Carbs are front-loaded earlier in the day, protein stays roughly even meal to meal, and fat rises later to fill the gap.

Why the shift across the day: insulin sensitivity is highest in the morning and declines as the day goes on, so the same carbs eaten at breakfast produce a smaller blood-sugar swing than they would at dinner - carbs are shifted toward earlier meals to take advantage of that. Protein is kept nearly flat across meals because muscle protein synthesis responds better to a steady supply (roughly 25–30g per meal, several times a day) than to one large dose. Fat has no comparable timing effect, so it's used to fill in the calories carbs leave behind later in the day.

Example meals

Two simple dish ideas per meal, roughly matched to that meal's macro emphasis.

These are illustrative dish concepts, not precise recipes - actual calories and macros will vary with the specific ingredients, brands, and portion sizes you use. Treat the numbers above as a target to build toward, and check real nutrition labels or a food-tracking app for anything close to precise.
