How Many Calories Should I Eat a Day?

Your daily calorie needs depend on age, sex, height, weight and activity level. TDEE is a useful estimate of total daily energy expenditure.

Start with BMR

Basal Metabolic Rate estimates energy used at rest. An activity factor can then be used to estimate TDEE.

Maintenance, weight loss and weight gain

Maintenance planning often starts around estimated TDEE. Weight loss may involve a moderate reduction, while weight gain may involve an appropriate increase. Individual needs vary.
