I want to know the same thing. I have been exercising for 5 weeks and cutting calories and have not lost even an ounce...I feel like it is for nothing...I eat 13-1800 cals daily and burn at least 500 of those daily so I am running a 500+ deficit of caloric intake. I work out 5-6 times a week. 45-90 minutes of cardio with weights every other day. AND I have included whey protein (within the 13-1800) so, why am I still fat?

There are excellent reasons to be physically active. We might just enjoy exercise. We may increase our overall fitness; we may live longer, perhaps by reducing our risk of heart disease or diabetes; we’ll probably feel better about ourselves. But we will not lose weight. Exercise will actually make it harder to lose weight as your appetite will be activated in a way that makes you not only put back the calories you burn but then some.

Losing weight is always a matter of burning more calories than you consume. So a person must be willing to walk around hungry. By exercising that hunger will be greater than if you did not. Losing weight ultimately becomes about diet - what you eat as much as how much.
