NUTRITION

Macronutrients

Macronutrients are the nutrients your body needs in large amounts — protein, carbohydrates, and fats — each playing a distinct role in weight management.

Macronutrients, or "macros," are the three main types of nutrients in food: protein (builds and repairs muscle), carbohydrates (your body's main energy source), and fats (essential for hormones and cell health). The balance of these affects your weight, energy, and overall health.

Protein provides 4 kcal/g, carbohydrates 4 kcal/g, and fat 9 kcal/g. Protein has the highest thermic effect (20–30% of its calories are used in digestion) and is the most satiating macronutrient. Medical weight management programmes manipulate macronutrient ratios to optimise fat loss while preserving lean mass.

Adequate protein intake is especially important during weight loss to prevent muscle loss. Dr Joseph Wang can advise on appropriate macronutrient targets for your individual needs.
