Caffeine in fitness and weight loss products comes from a variety of sources such as kola nut and green tea extract.

Caffeine is an alkaloid, a methylxanthine that stimulates hormone-induced fat burning. Caffeine works by increasing free fatty-acid concentrations and adrenaline levels. This results in greater lipolysis (oxidation of fats for energy), which can drain your fat stores over time. This change in a muscle’s utilization of energy substrates can have a profound effect on fat loss. Caffeine also heightens mental alertness, which can positively affect your motivation to exercise and create the caloric deficit needed to lose body fat.

 

Caffeine is rapidly absorbed by the body and remains in circulation for more than seven hours. Plasma concentrations reach a peak one hour after it is consumed. It is then slowly metabolized, with a half-life of four to six hours.

Caffeine has been shown to dramatically increase free fatty-acid levels, providing the body with a fuel source that it can use instead of the glycogen stored in your liver and muscles. In fact, one (not related to Betalean Hp) study found a 100% increase in plasma free fatty acids after the subjects took 330 mg of caffeine.

At the same time, caffeine has been shown to increase adrenaline levels. This “fight-or-flight” hormone increases alertness and boosts energy levels, helping you to go through your daily tasks with less food intake. Most people experience a reduced appetite when their adrenaline levels are high, usually because they are focused on more essential tasks. With these two mechanisms, it’s easy to understand why caffeine is used in weight-loss products, and is important for jump-starting your weight-loss efforts.
