Apologies
I though I tried to explain that not all people can lose weight through exercise or eating less.
So that mean the Majority of people CAN lose weight through the conventional means (eating less fatty foods than they normally would etc.).
I was only stating that they are cases (might be 5% - could closer to 1-3%) a VERY SMALL percentage of people who will gain weight and will be unable to lose that weight.
Is what I said clearer now?
