Frequently Asked Questions
What is BMR?▾
Basal Metabolic Rate is the calories your body burns at complete rest to maintain basic functions like breathing and circulation.
What is TDEE?▾
Total Daily Energy Expenditure = BMR × activity factor. This is your total calorie burn on a typical day including exercise.
How does the −500 calorie deficit help with weight loss?▾
A 500 kcal/day deficit creates approximately 3,500 kcal/week deficit, which corresponds to roughly 0.5 kg (1 lb) of fat loss per week.
