Coffee and Caffeine FAQ

Caffeine causes weight gain not loss. It does this by increasing the body's stress response and initially elevating adrenaline (an appetite suppresant) and cortisol, which stays in the blood much longer, which tells the body to eat and store fat. So in other words, when you drink coffee, initially you will not be hungry. Later though, you will be hungry for carbs sugar and fat and likely overeat. This is the natural effect of cortisol, whose job it is to replenish energy stores that were used. To make it worse, caffeine effects length and quality of sleep, and less, poor sleep causes weight gain.

Unfortunately, it is very difficult to quit, as it is extremely addictive, with even people who have other serious caffeine related problems unable to do so. Most men women and children are drinking more caffeine then ever, and obesity and other diseases have never been higher. Most people who have successfully quit caffeine (over a year) will tell you it was the hardest thing they ever did, tougher then quitting cigarettes or amphetamines.
