The core mechanism of fat loss is energy deficit: when calorie intake is less than consumption, the body uses fat stores for energy.
Body fat percentage affects both appearance and health directly. Healthy body fat for men is 10%~20%, ideal around 15%; for women it's between 18%~28%.
For lean people, the key to fat loss and body shaping is 'muscle building primary, cardio auxiliary'.
During fat loss, intake is recommended at 1900-2100 kcal, with daily deficit of 300-500 kcal.
Maintaining low body fat is more challenging than losing it. The human body is naturally inclined to store energy.
