id imagine so yes

Nope, just a myth. Fat reduction takes time. There are no miracle pills or methods regardless of any anecdotes, celebrity endorsements, or late night TV shows you may have seen or heard.
1. Diets to lose fat don't work because the body goes into a kind of starvation mode where it squirrels away every spare calorie as fat and will cannibalize bone and muscle tissue for energy.
2. Weight is a very poor metric because bones, muscle, and fat all have different densities (fat being the lightest). The correct metric is the percentage of body fat. You can lose fat, look better, and not lose any weight. See your doctor to determine your current percentage and what your ideal percentage of fat should be.
3. Eating balanced meals as recommended in the Harvard Eating Pyramid and exercising at your target heart rate is the best way to reduce the percentage of body fat.

4. Any exercise that is performed at your target heart rate for an extended period will burn fat. Walking, cycling, and rowing are some of the best. Use a pulse meter to ensure that you are exercising at the correct intensity. Too intense and you just burn sugar, not fat.

For most people yes,all the evidence suggests that.

it does as long as you work out so any protein youre eating is getting used properly and doesnt get a chance to turn to fat.
