Metabolism is the set of life sustaining chemical changes with in the cells that change food to energy.
Metabolism goes up for two to three hours after eating because of the extra metabolic processes required to digest food and absorb its nutrients.
How we eat has an impact on how many calories we burn, eating for 10 minutes can burn 30 calories.
The benefits of exercise are two-fold. First, aerobic activities such as running, cycling and brisk walking increase the amount of calories we burn.
Aerobic exercise can lead to the afterburn effect, where the body continues to burn calories faster for many hours.
