Frequently Asked Questions — Calorie Calculator
How many calories do I need to lose weight?
To lose 1 pound per week, create a 500 calorie/day deficit below your TDEE. To lose 0.5 lb/week, cut 250 calories/day. Losing more than 2 lbs/week (1,000 cal deficit) is generally not recommended without medical supervision.
How are my daily calories calculated?
The calculator uses the Mifflin-St Jeor formula to find your BMR, multiplies it by your activity level to get TDEE, then adds or subtracts calories based on your weight goal. A minimum of 1,200 calories/day is enforced for safety.
What is the macro breakdown based on?
The default split is 25% protein, 50% carbohydrates, and 25% fat. Protein and carbs provide 4 calories per gram, fat provides 9 calories per gram. This is a general-purpose split — athletes or specific diets may use different ratios.
