Our expert says:
Belly fat is caused by fat deposition in the abdominal region due to a variety of factors such as excessive energy intake from any source (fats, carbohydrates and even proteins) and too little energy output via daily physical activity and exercise. The news this morning that 68% of the population in the UK are physically inactive and slothful, is probably just as applicable to South Africans, and this lack of exercise is just as important to adiposity as any diet. Ageing also plays a role, as do hormonal disturbances including PCOS, and endocrine receptor disruptors. The latter chemicals contaminate our water supplies and foods. It is important to keep in mind that anyone who increases his or her energy intake immoderately by drinking alcohol of any type, not just beer, will gain weight and such weight can be deposited in the abdomen. Alcohol per se provides the second highest quantity of energy per gram, namely 29 kJ per gram (Fats have the highest energy content at 37 kJ per gram). Most individuals cannot sustain a very-high-protein, high-fat diet for long periods. Also remember that the balanced approach to nutrition recommends that we eat healthy fats in moderate quantities, adequate amounts of lean protein and adequate amounts of unprocessed, high-fibre, low-GI carbohydrates. Moderation is the key. Advocating any one macronutrient over any other macronutrient, can lead to dietary imbalances.
