    it's a unit of energy in food the body uses to function. calories in a diet come from carbs (4 per gram), protein (4 per gram), fat (9 per gram), and alcohol (7 per gram).

    I think the notion of calories is become more suspect. Two foods may have the same amount of calories but one will be much more likely to cause increased body fat than the other because not all calories are the same and are not absorbed by your body the same way.

    calories don't make you fat. fat makes you fat. taking in less calories allows a body to use stored fat for energy instead of a surplus of calories.

    But can you take in more calories and get the same effect if the calories you are taking in are not absorbed as well as typical calories? I think more study needs to be done so that calories can be measured in terms of what they actually do to your body.

    depends on where the calories are coming from as to how the body uses them. for example, calories from protein are used more efficiently due to increased metabolic rate than calories from carbs.

    you, sir, are correct.

    I tried the low carb diet and it worked for as long as I could do it. I think there is a piece missing to it though. I do not think all carbs are equal and I do not think all calories are equal.
