Ephedrine and Caffeine in Betalean Hp
Renowned weight-loss expert Arne Astrup, MD, and his associates performed a study with ephedrine at the University of Copenhagen and two Danish hospitals. Five young females were given 20 mg of ephedrine three times per day one hour before meals and were told to continue eating normally. Even though there was no dieting involved, the women lost an average of 2.5 kg of body weight after four weeks and 5.5 kg after 12 weeks. They also held onto their lean muscle, while their body-fat percentage dropped by 3.5% after four weeks and 5.2% after 12 weeks. Two months after the experiment stopped, they had only gained back 0.5 kg. The only side effect was a mild rise in blood pressure at the start of the experiment.
Two studies by the same Danish researchers indicate the benefits of combining ephedrine with caffeine. In both studies, the participants took a supplement with 20 mg of ephedrine and 200 mg of caffeine three times per day. They also followed a low-calorie diet. In the first study, the test subjects lost 16.2% of their body weight in 24 weeks, significantly more than the 13.4% loss by the placebo group. The second study confirmed that most of this loss was body fat. In that eight-week study, the E/C group lost 10.1 kg, compared to only 8.4 kg with the placebo. But the E/C group lost twice as much fat (9.0 kg vs. 4.5 kg) and much less fat-free mass (1.1 kg vs. 3.9 kg). Only mild side effects were reported.
The E/C combination has been extensively studied, but space limitations do not allow a detailed listing of the many studies that have showed benefits. All of this research, however, supports the effectiveness of the E/C stack and demonstrates the moderate level of side effects when you take appropriate dosages.

A study in the American Journal of Clinical Nutrition found that when green tea was taken instead of pure caffeine, the thermogenic effects were even stronger. This six-week study compared the benefits of pure caffeine (50 mg), green tea extract (with 50 mg of caffeine and 90 mg of EGCG) and placebo. The pills were given three times per day. The green tea group experienced a significant 4% increase in thermogenesis and a 4.5% boost in overall energy expenditure.
Research suggests that supplementing with tyrosine may minimize the degradation of the neurotransmitters involved in the metabolic process while enhancing the thermogenic effects of the ECA stack. With more raw material available, the neurotransmitters controlling metabolism are produced at a higher level with beneficial results. The increases in alertness and energy level will also make it easier to stick to your diet program.
Most of the studies on alpha lipoic acid have been done with diabetics, who often have a problem with insulin sensitivity. These studies have found that this coenzyme can increase the body's sensitivity to insulin, reducing the amount of insulin that needs to be produced by the pancreas (or injected). Nondiabetics also produce alpha lipoic acid, so it stands to reason that it would promote better utilization of insulin for them as well. Alpha lipoic acid is also a potent antioxidant, helping to fight free-radical damage in the cells.
Numerous studies have indicated that naringin prolongs the chemical activity of caffeine. Research published in the British Journal of Clinical Pharmacology found that the half-life of caffeine was extended by 31% when naringin was present in sufficient amounts. Studies of various citrus fruits have shown that grapefruit has by far the highest content of naringin. It is, in fact, what gives grapefruit its characteristic bitter taste.
An eight-week study with six overweight females found that Coleus forskohlii can significantly reduce body weight while increasing lean body mass. The subjects were given 250 mg of an extract standardized to 10% forskolin twice daily. One capsule was ingested in the morning and the other in the evening, half an hour before each meal. Subjects were instructed to maintain their normal activity levels and dietary practices. After four weeks, there was an average loss of 4.3 lb of body weight. After eight weeks, the subjects lost an average of 7.2 lb, and their body fat percentage dropped from 33.6% to 25.9% as determined by bioelectrical impedance. No significant side effects were noted, although blood pressure tended to decrease during the experiment.
While the Betalean research presented here sheds light on the science behind Betalean Hp, as with any fat burner, the only real way to determine its effectiveness is to actually try the product out for yourself.
