What Is a Calorie Deficit?

A calorie deficit occurs when you consume fewer calories than your body burns in a day. Over time this forces the body to use stored energy (fat) for fuel, producing weight loss.

Key Facts

How it works: When intake is below total daily energy expenditure (TDEE), the body draws on fat stores.
Safe rate: A modest deficit supports gradual, sustainable loss without crashing metabolism.
Too large backfires: Extreme deficits lower BMR, increase hunger, and often lead to rebound weight gain.
Quality counts: Foods high in protein and fiber keep you fuller and support muscle maintenance during a deficit.
