The answer is no; all calories are not created equal. It is a common myth in the fitness world that weight loss or weight gain is simply a matter of how many calories have you consumed and how many have your burnt; i.e. a calorie is the same whether it is obtained from proteins, fat or carbohydrates. But this is not the case. For example; just consider two groups – Group A consumes 2000 calories from pizza, soft drinks, hot dogs and coffee while Group B consumes the same 2000 calories but from vegetables, fruits, chicken, fish and oatmeal. Now would you say Group B calories are better than Group A? This is because the nutritional value of the calories ingested by Group B is much higher than Group, A which makes it different.
