Q What To Eat/Drink Before Exercising To Burn Maximum Fat?A. To burn fat, you’ll need to increase the amount of protein you eat  and reduce carbohydrates. Ingesting only for whole grain carbs such as raw oats, brown rice, wholemeal pasta, quinoa or sweet potatoes will help. Aim for the same size in portions of protein and carb on your plate. so for breakfast, choose either skimmed or soya milk, a boiled free-range egg (limiting eggs to five a week) or yogurt for protein, and team it with either a cup of raw oats topped with sliced apple, a banana, or two slices of wholegrain rye bread for carbohydrates. Add a dessert spoon of flax or pumpkin seeds for essential fats (which don’t impede fat burning). For lunch and dinner, team carbs like brown rice, sweetcorn, broad beans or couscous with proteins like tofu or other soya products, cottage cheese, fish or lentils — then have double the quantity of non-starchy vegetables such as broccoli, runner beans, kale or tomatoes. This way you don’t flood your blood with glucose (the breakdown product of carbohydrate that our bodies use as fuel and convert to fat if there’s an excess), and that helps to bum fat and balance energy levels. Eat nothing for at least an hour, preferably two, before you exercise, but drink plenty of water to stop you from becoming dehydrated. And avoid all coffee, tea, colas — even diet — as stimulants can play merry hell with blood sugar too .
