Coffee is one of the most popular food items in the world and is loaded with caffeine. Caffeine metabolism acts fast. It absorbs into the bloodstream quick. It is a psychoactive substance. It is a member of the alkaloid families and found in over 60 different plant species with the most famous being the cocoa bean, coffee bean, tea leaves, chocolate and cola nuts. It metabolizes in the liver. It is in many over the counter drugs.
Women metabolize caffeine faster than men. It increases fatty acids. It targets the central nervous system. It speeds up metabolism and some say it helps burn calories faster but doesn't mean it will help you lose weight. It is a natural pesticide that kills insects feeding on the plant. It takes approximately three to six hours for half of your consumed caffeine to leave your body.
Not all caffeine substances are the same. It has some benefits but my research indicates that little to no benefits are from coffee. The caffeine in coffee reverses the positive effects of caffeine. Coffee apparently has other compounds that block the benefits of caffeine.

Caffeine has a lesser effect with a high carbohydrate diet. More carbohydrates are extra important if you are an endurance athlete, because it keeps you from burning up your protein which is not meant for energy. It would not be wise to skimp on carbohydrates in order to consume more caffeine.
