There is one way to lose weight[...] - one ECA pill every morning until you're done.

I'm 86 kg (bmi ~27). I took your advice and tried taking one ECA pill every morning for the last few weeks and...I was gaining weight on it. I think I had a little loss of appetite right at first - along with a feeling of being "wired" - but the effect wore off after a day or two.

One confounding factor is that I normally consume a lot of caffeine (~200 mg) daily in the form of Diet Coke. I cut back a bit on the soda while taking ECA, so the change in my caffeine consumption while taking ECA compared to baseline was quite small - perhaps being a prior caffeine addict renders ECA less effective?

As with Shangri-la, one might conclude any of the following: (a) I just need to take more ECA (b) I just need to stick with it for longer - eventually the effect will kick in (c) It works for some people but not others for as-yet unidentified reasons (d) it doesn't work, and other factors explain the apparent success in some
