Health Effects of Calories
Calories represent the energy content of food, measured in kilocalories. The body uses this energy for basal metabolism, physical activity, and the thermic effect of food.
Chronic caloric deficit leads to weight loss, muscle wasting, fatigue, weakened immunity, and in severe cases, marasmus. Prolonged restriction impairs cognitive function and hormonal balance.
Sustained caloric surplus leads to weight gain and obesity, which increases risk of type 2 diabetes, cardiovascular disease, certain cancers, and metabolic syndrome.
Absorption & Interactions
Energy is released through digestion of macronutrients: protein and carbohydrates yield ~4 kcal/g, fat yields ~9 kcal/g, and alcohol yields ~7 kcal/g. Fiber provides ~2 kcal/g.
