Meal Calorie Split
Calculator

It takes your total daily calorie target and distributes it according to a chosen split (such as equal thirds for three meals, or a custom percentage breakdown like a larger breakfast and lighter dinner), returning a calorie target for each meal.

No single split is proven optimal for everyone — research on meal timing and frequency shows mixed results for metabolism and weight management, so the right split is largely about what fits your schedule, hunger patterns, and adherence rather than a scientifically mandated ratio.

For most health outcomes, total daily calorie and nutrient intake matters more than precisely when those calories are eaten, though some people find certain distributions (like a larger breakfast) help with appetite control and adherence — this is individual rather than universal.

If you regularly eat snacks, it's more accurate to include them as their own allocation in the split rather than lump them into the nearest main meal, since doing otherwise makes individual meal targets look larger than what you actually eat at that sitting.

Use the calculated numbers as a flexible guide rather than a strict rule — as long as your total daily intake stays close to the overall target, some day-to-day variation in how calories are distributed across meals generally doesn't undermine your broader nutrition or weight goals.
