Meal Calorie Calculator: Calories per Meal
Enter your daily calories and how many meals you eat; get a target for each meal, with protein, carbs and fat.
How it’s calculated
This estimates your daily calories (Mifflin–St Jeor × activity) and divides them evenly across meals.
Per-meal calories = daily calorie target ÷ number of meals (default 3).
Source: Mifflin MD, St Jeor ST, et al., 1990, for the daily estimate.
How many calories per meal?
Divide your daily target by the number of meals, then shift 10–20% toward the meal around training or the one where you are hungriest. On 2,000 calories and four meals that is about 500 each, or 600 / 500 / 500 / 400. Protein works best spread evenly — 25–40 g per meal for most adults.
Example 1,500 / 2,000-calorie day
1,500 calories, 3 meals + 1 snack: breakfast 400, lunch 450, dinner 450, snack 200. 2,000 calories, 4 meals: 500 each. In both cases keep protein at roughly a quarter of each meal’s calories and fill the rest with vegetables, whole grains, fruit and healthy fats — the pattern recommended by the Dietary Guidelines.
Meal timing: does it matter?
For weight, total daily calories matter far more than when you eat them. Timing helps in two places: protein every 3–4 hours supports muscle, and a carbohydrate-containing meal 1–3 hours before hard training improves performance. See the nutrient timing guide for details.
Meals vs snacks
Snacks are not “extra” — they are part of the daily total. A planned 150–250-calorie snack with protein and fibre (yogurt and fruit, nuts, hummus and vegetables) prevents the unplanned 500-calorie one. Check our Nutrition Facts pages for exact values.
