To lose weight and keep fit, you must have a good diet and regular exercise to burn fat. The first thing you must understand is that about the only fact that burn calories does not mean fat. The emphasis on exercise, you lose body fat, and you can not lose body fat burn calories. If the performance of our institutions is the burning of calories, but calories, calories, carbohydrates in our system. To burn calories from stored fat, the body requires the presence of oxygen. There is a certain amount of oxygen that your body needs to burn the fat and the only way for you the amount for your body, your heart rate during training. You understand that if they continue to burn the calories in carbohydrates, lost weight, mostly water, which results in a decrease in metabolism. So, think about the calories burned from carbohydrates as energy source of calories. If you have a lot of calories to lose energy, so the muscles are not enough energy for metabolism, indirectly, to burn fat. Therefore, it is your duty calories if you're on an exercise program to replace your energy to burn calories. Fat calories during training While aerobic exercise, your body goes through several stages before the point where you are fat. We have been told that only the burning of sugars (carbohydrates) not fat in the first 10 minutes of exercise. This applies to a certain extent. I say this because we continue to burn sugar for 10 minutes mark, if you're not hard enough for the body more oxygen to be desired, or you are working in difficult conditions and it is not possible to your body with enough oxygen for fat. If the exercise is expected to be stable (not too fast or too slow), your body use your stored fat (no sugar or carbohydrates) as energy source. Also, remember that just because during the fat does not mean that you can stay. Staying in the back stage of fat depends on whether it moves at a pace that is right for your body. Make sure your heart rate zone target. Calories from fat in the quiet The only way to continue to burn fat calories hours after you finish working through the power of anaerobic exercise. Weight training is the key to burning fat in the calm. The gym is an anaerobic activity, which means to burn more calories as aerobic exercises. The calories you burn during strength exercises are mostly calories of carbohydrates (for example, you must eat more calories a day for energy), but the calories burned in a quiet area are the majority of calories from fat. The reason you're fat in a quiet area, as the weight increases metabolism, energy stored as fat. To burn the body fat last machine you have to do aerobic (heart) and anaerobic (strength) exercise.
