Macro Calculator

Daily protein, carbohydrate and fat grams for a calorie target and a goal. Calories come from the Mifflin-St Jeor basal rate times an activity factor, shifted by 500 kcal down to lose or 300 kcal up to gain and never below 1200, and are then split three ways: balanced 30/40/30, low carb 40/20/40 and high protein 40/30/30. This is an indication, not medical advice.
