How does exercise help you lose weight if muscle builds on fat?
the bigger your muscle becomes, bigger consume of energy after exercise. After aprox. 20 min of exercise you will use your energy from the fat, and if your intake of energy is less than your consume, is just math. Muscle doesn't build fat (it burns it) and muscle weighs more than fat. If you became a body builder and had good muscles and then years later didn't bother to keep up your exercise regime this is when the muscle would turn to fat. Muscle cannot turn to fat. But if you do not continue working it you will lose muscle mass and burn less calories. If you do not eat less or exercise more to compensate for this reduction in muscle mass than you will gain weight back in the form of fat.
Does the brain burn calories?
There are a load of factors that change this number. For example, a toddler's brain is smaller and not functioning the same way as a college grad's brain is. Also, if the brain is functioning more (thinking more, dealing with harder tasks like writing, puzzles, driving, cooking, ect.), then it will also require more calories. A simple base is about 400 calories a day or so.
What kind of muscle burns most calories?
Muscle is muscle. A pound of muscle burns about 35-50 calories a day, so the more muscle you have, the more calories you burn. If you're looking to put on muscle in order to burn more calories in your diet, then you should work your entire body to allow each body part to grow, and give each part a few days rest in order to recover and rebuild.
