Caloric deficits play a pivotal role in fat loss and body recomposition. When you consume fewer calories than your body expends, it creates an energy imbalance that forces your body to tap into stored energy reserves, primarily body fat. This process is governed by the fundamental principle of energy balance, where net energy intake influences body weight. To achieve a caloric deficit, you can either reduce your food intake or increase your energy expenditure through physical activity.
Understanding your Total Daily Energy Expenditure (TDEE) is crucial for implementing an effective caloric deficit. TDEE encompasses your basal metabolic rate, thermic effect of food, and physical activity level. By calculating your TDEE and strategically setting your caloric intake below this threshold, you can create a sustainable deficit for gradual fat loss. However, it's essential to maintain a balanced diet rich in nutrient-dense foods to support overall health and performance while in a caloric deficit.
