Have seen this mentioned a few times now. I know caffeine is meant to be a good fat metaboliser, but does this really work well?

I've been bullking up, and my training/weight gain has been going really well, only thing is, I want to shift the layer of fat off my stomach to expose my abs a bit more, without easing off the muscle gain.

Naturally I'm going to stay on the protein, and lay off the carbs a bit. But again, I don't want to lay off them too much just yet as I need the energy for my training!

Any ideas for the best way to keep the balance right?

I've seen fat metaboliser tablets with green tea, caffeine etc in it, but they're big tablets, and I've always had difficulty swallowing big tablets. At least with pro plus they're tiny tablets and easy to swallow. I don't particularly enjoy green tea as a drink, but would happily suffer it for a worthwhile gain
