Frequently Asked Questions

What does TDEE mean?

TDEE stands for Total Daily Energy Expenditure, which is the total number of calories your body burns in a day from basic body functions, digesting food, and all physical activity combined.

How is it different from BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs just to stay alive at rest, while your daily energy expenditure adds the calories you burn through movement, exercise, and daily tasks.

How accurate is this calculator?

Most calorie calculators can only provide an estimate based on population formulas, so this gives you a solid starting point, but you may need to adjust your intake up or down over a few weeks based on how your actual weight changes.
