Losing weight has a simple equation, eat less calories then your body needs and the weight will melt off. The most effective, safest and healthiest way to do this is to exercise and control your diet. You should aim to burn between 500Kcals to 1000Kcals per day. Beware though because if you burn more than 1000 calories per day, you will lose muscle, not fat and muscle helps burn that fat. Also do not attempt starving yourself as this will slow down your metabolism and 10% of the food you eat is used to digest the food you’ve eaten. Low carbohydrate diets can cause illness as carbohydrates fuel muscles and give you energy. Protein diets are also dangerous because if you eat too much protein, your body enters a process called ketosis. This damages your muscles and bones. Aim to eat a balanced diet and always try to get your 5 fruit and veg a day.
