Almost no natural supplements I could find research on worked. There is a range of very small and weak trials for 24 supplements that showed a very minor effect and were almost always funded by the manufacturers which means they would only ever publish the results that supported their product. Some of these, like ephedra or ephedrine, I mentioned in the last talk have potentially serious side effects.
Now some people argue “but I lost weight on it”, perhaps 1-2 kg. There are really 3 things to say to this – 1. Maybe you just focussed on losing weight more with other measures like you ate better and moved more, AND you did this other thing and so, of course, you lost weight 2. Most people fluctuate a few kilograms on any given day so was this a true weight loss? 3. Maybe it did help you lose weight, but was that amount worth the $50 a month or $100 a treatment, potential side effects and are you any healthier?
The most common approaches I hear about are hypnotherapy, cold exposure, infrared sauna, green tea, acupuncture and homoeopathy. So let’s look at these separately.
In the end – I am not here to tell you what to do. Just to help you make an informed choice.
