Most people are aware that exercise is beneficial for weight loss but knowing approximately how many calories are used during a workout can be a useful motivator. Many people are surprised, however, how few calories an hour of exercise really uses. This helps to reinforce the idea that you “cannot outrun a bad diet” and that eating less is often easier than trying to exercise more.

 Disadvantages

It is generally accepted that protein contains four calories per gram, carbohydrates contain four calories per gram, alcohol contains seven calories per gram and fat contains nine calories per gram. This premise suggests that all calories are equal irrespective of their source. This, however, is not true, and fails to take into account how calories from different sources are treated in your body.

Different foods require differing amounts of energy to digest, transport, utilize and eliminate. This is commonly referred to as the thermic effect of food, TEF for short. TEF means that, of the food you eat, some of the calories contained in that food are used in the process of digestion etc.
