Calorie deficit basics

Learn · Lose fat

Fat loss requires eating fewer calories than you burn over time. A moderate deficit (roughly 300–600 calories/day, or about 0.5–1% of bodyweight lost per week) preserves more muscle and is easier to sustain than crash dieting. Faster is not better — aggressive deficits increase muscle loss, hunger, and the odds you quit.
