dude.. I've seen that argument so many times, but most people just understand it when I explain it to them like this:
Let's say you need 3000kcals to maintain your weight.
Let's say you are also eating 3000kcals
You then add some training, burning 500kcals.
It does not matter where those 500kcals came from, because at the end of the day, you have 500kcals less than your body needs, the body will then need to get 500kcals from somewhere, which will be tissue in the body, usually fat (although some muscle might go along with it).
If the calories burned are just sugar, the body will eventually need to make up for the loss and as long as you don't eat more than those 3000kcals, the only way the body can make up for it is by eating a bit of itself.
Also, take the same numbers, but say you are eating 4000kcals and the 500kcal exercise is all taken from fat stores in the body, you are still 500kcals over your maintenance, your body will want to store this as fat to use later. So even if you burned fat during exercise, the body will put it back on if you don't have a deflect.
How is that for a simple explanation. :p
