Is caffeine an appetite suppressant?

I did a quick search, and according to most health professionals, yes, caffine does supress your appetite, though only on the short term. Many diet pills on the market use caffine as a way to keep you from eating, but doctors don't reccomend using caffine for this purpose over a long term period, as too much caffine eventually will raise the cortisol levels in your body. Cortisol in your body helps to regulate your blood sugar and inslin levels, and increasing this can actually cause you to eat MORE food. So the small amount of caffine you were taking in probably were reducing your appetite some, and now that you have cut it out, you probably will feel a little hungrier at times.

I am nor Sure about that, it seems like it is, I would also imagine that drinking a lot of lliquid will give anyone a feeling of being full too.
