Diet plays a major part in any sort of weight loss effort. In the end, the food you consume determines what number of calories you take in everyday. Eat less, burn more calories, and you'll be slimming down in to time. If perhaps it were that easy though.

Considering the explosion today of 4hour+energyshots that have little caffeine, I challenge the importance of caffeine in weight loss products as well as energy drugs on the whole. One major problem is the fact that there are plenty of sources of caffeine in the diet, including coffee, chocolate, soda pop (regular) and diet and here just above each dietary supplement. Most pre-workout NO products contain some kind of caffeine.
