Take Home Message
From the 12, these are the clear winners, with all the best evidence to back up them:
Weight loss: Glucomannan, CLA and Orlistat (Alli).
Enhanced fat loss: Coffee and green tea extract.
However, against CLA, and I’ve to recommend against Orlistat because of the unpleasant side effects as a result of damaging effects on metabolic health.
That leaves us with glucomannan, green tea extract and caffeine.

Cutting carbohydrates and eating more protein remain the most effective ways are more effective than most of the diet pills combined, and to shed weight.
