Coffee is actually good for you in moderate amounts. Five cups per day may be pushing it.

Effects of coffee on the body:

*Adenosine- Can inhibit absorption of adenosine, which calms the body, which can make you feel alert in the short run, but can cause sleep problems later. (More on this below.)
*Adrenaline- Caffeine injects adrenaline into your system, giving you a temporary boost, but possibly making you fatigued and depressed later. If you take more caffeine to counteract these effects, you end up spending the day in an agitated state, and might find yourself jumpy and edgy by night.
*Cortisol- Can increase the body's levels of cortisol, the “stress hormone”, which can lead to other health consequences ranging from weight gain and moodiness to heart disease and diabetes.
*Dopamine- Caffeine increases dopamine levels in your system, acting in a way similar to amphetamines, which can make you feel good after taking it, but after it wears off you can feel ‘low'. It can also lead to a physical dependence because of dopamine manipulation.

Because coffee is so acidic it also forces the creation of fat cells in your stomach in an effort to keep the coffee away from your stomach. Yes, coffee can give you pudge.
