To be honest, it's fine for me when I go to the gym, I find the four packs a day do me fine. I'll just have one of those as a bar an hour or so before.
Claire, what are you doing at the gym? Cardio or resistance or a mixture of the two? Are you finding that while not losing many pounds you're losing inches? The only reason is that I'd really encourage you not to be discouraged just because you're probably gaining more muscle which obviously has a weight to it. So you'll probably find you're losing more than 1.5lbs of fat but maybe gaining a couple of pounds of muscle, but that your inches are coming down. I wouldn't worry about it, the muscle gain will plateau a bit weight wise. Unless you're going really mad!
