If a friends comes to you and tells that he has lost some weight successfully, your immediate question would be “How much pounds did you lose?”
Let me tell you that losing weight is all about losing fat not pounds so in effect, you can stay overweight even after you weigh less and even more interestingly you can get fatter while your weight stays the same!
Once in the past, it was an implicit fact that losing fat was what you were looking for if you were trying to lose weight but now, most of the people don’t even know that muscle loss is not at all useful in their goal of losing weight.
In effect, muscle (and water) loss makes you fatter technically because after losing 10 or 20 pounds of lean mass while losing only 2 pounds of fat, your body fat percentage increases!
So how to determine if you have actually lost fat? The best way is to use Body Fat Percentage but the problem with using it is that it can be measured in a lot of ways and is generally a very loose approximation of the actual value. Its accuracy decreases even more if you are shaped a little differently than the average person.
Body Mass Index, on the other hand is a more accurate measure but virtually fails completely if your lean body composition is different from that of an average person because the BMI assumes that your muscle mass quantity and composition is similar to an average person.
Anyway, my point is to signify that pound loss is not fat loss and in most cases when you lose 10 to 30 pounds with a fad diet, 80% of that is muscle loss and so such fad diets makes you fatter not slimmer!
