A calorie deficit occurs when the number of calories you consume is less than the number of calories your body uses. This imbalance forces your body to tap into stored energy, primarily fat, to meet its energy needs. As a result, this leads to weight loss over time. It is often a goal for people trying to lose weight or manage their body composition.
