The biological math behind every calorie your body burns
In short: Ever wonder how your body actually converts food into movement? This video explains the mechanics of energy metabolism, from cellular fuel to the specific variables that dictate your daily caloric needs.
The human body extracts energy from three primary macronutrients: lipids, proteins, and carbohydrates. This fuel powers essential life processes, including nerve function, muscle contractions, and the maintenance of internal body temperature.
The video explores the calculation of Basic Energy Requirements (BER), which fluctuate based on individual factors like age, body mass, physical activity levels, and pregnancy. It also examines the physiological consequences of nutritional imbalances, ranging from obesity and stunted growth to deficiency diseases like rickets and anaemia.
