Eat enough
If you eat too few calories, your metabolic rate will automatically drop. This is a self preservation mechanism, which kicks in when your body thinks you are starving. The safest bet is to eat about 250 calories less than you need at the sedentary level and to take 250 – 500 calories of exercise each day to give a steady weight loss of between one and two pounds a week.
4. Eat Lean Protein
It takes more energy for the body to digest protein than carbohydrate or fat. Studies have shown that people who eat a high-protein diet burn more than twice as many calories in the hours following their meal as those eating a high carbohydrate diet. While the safety of high-protein diets can be disputed, it does make sense to include some lean protein as part of each meal.
5. Eat Fibre
Food with lots of fibre also gives your thermic metabolism a boost. High-fibre foods like beans, fruit, vegetables and whole grains simply take longer to digest and therefore help burn more calories.
