If you follow a strict diet and exercise regularly, there's only one factor missing to lose weight or get lean! Our most powerful weapons are thermogenic fat burners, which increase the number of calories burned by increasing body temperature. These products increase fat burning by raising blood pressure and pumping up the heart, and also boost our performance during workouts. However, we've also thought about people with cardiovascular disease, who can also reap the many weight loss benefits of our stimulant fat burners. Examples of fat burning ingredients include: l-carnitine, CLA; conjugated linoleic acid and HCA; hydroxycitric acid.
