What is a calorie deficit?

A calorie deficit is when you consume fewer calories than you burn. If you consume 2000 calories and your Total Daily Energy Expenditure (TDEE) is 2500 calories, you will be in a 500 calorie deficit. A calorie deficit is a fundamental underpinning to any effective weight-loss strategy — if you're in a calorie deficit, you will unequivocally lose weight/body fat over time.
