A calorie deficit occurs when you consume fewer calories than your body burns each day. When this happens, your body uses stored energy, including body fat, to make up the difference, which may lead to weight loss over time.

A moderate deficit of approximately 300–500 calories per day is commonly used to support gradual and sustainable weight loss. Individual needs may vary based on age, activity level, and overall health.

Beginners and individuals returning to exercise may be able to build some muscle while losing fat. Adequate protein intake and resistance training are important factors for preserving and developing muscle tissue.

As your body weight, activity level, and goals change, your calorie needs may change as well. Reassessing your calorie targets every few weeks can help keep your plan aligned with your progress.
