- caffeine does not suppress your appetite, although it does increase the level of circulating fatty acids, thereby enhancing fat oxidation. This is why caffeine is used by runners and endurance trainers, although it is most effective in non-habitual users. Also, contrary to popular belief, the effects of alcohol are not reduced by caffeine, although as mentioned above it can provide temporary relief from fatigue and drowsiness, and from migraine headaches.

Here is a good sight that explains it simply. http://www.andrews.edu/NUFS/caffeine.html

Caffeine is readily absorbed by the body, with blood levels peaking about 30 minutes after ingestion. The clearance rate from the blood varies from several hours in an adult to several days in a newborn. The clearance rate is decreased by pregnancy and use of oral contraceptives. Smoking, on the other hand, appears to increase the rate at which caffeine is cleared from the body. Hence, caffeine intake should be greatly reduced or eliminated by persons trying to quit smoking, so as to prevent increased caffeine levels in the blood and the possible increased craving for nicotine.

Caffeine can produce many effects including:

elevated blood sugar (gives the feeling of an energy surge)
elevated blood fats
increased blood pressure
stimulated central nervous system (may cause one to override the body's call for rest)
irregular heart beat
increased urinary calcium and magnesium losses (may impact on long-term bone health)
increased stomach acid secretion (aggravates a stomach ulcer)
tremors, irritability, and nervousness
insomnia and disruption of sleep patterns
anxiety and depression
heightened symptoms of premenstrual syndrome (PMS)

caffeine does not stop your appetite, even though it makes the level of circulating fatty acids go up which raises fat oxidation. that's why caffeine is used by runners and endurance trainers, even though it is most effective in people who don't use it a lot. The use of caffeine do not reduce the effects of alcohol, but it can give you teporary relief from fatigue and drowsiness, and from migraine headaches.

Although it does not stop you feeling hungry, caffeine can help get rid of the fatty acids in our system, which is why athletes use it. It can perk you up, but will not signifcantly reduce the effects of alcohol.

A somewhat simpler precis than the other answers!

Caffeine is an appetite suppressor. The debate is still open as to whether decaffeinated coffee is that much safer than regular coffee. As with most things, moderation is best.
