Ally is a joke. Clinical research has shown tepid results with Ally. It inhibits the metabolism of about 20% of the fats you ingest, so that you cannot absorb those dietary fats as calories.
Ally was being marketed like crazy as a miracle weight loss cure about ten years ago, and it sold very well. But I can say that I didn’t have any positive feedback from customers about it, just complaints about gastrointestinal issues. I got a lot of returns on it.
If you have a bad diet, and are eating an abnormal amount of fats, then it’ll help you a little. If you have a clean diet, it won’t do anything. Also, I really question the logic of NOT absorbing nutrients and calories that you’re ingesting. You should be eating to fuel and nourish yourself, not to spew your undigested food out the other end.
Being in the supplement industry for 12 years, I’ll tell you that weight loss supplements don’t work at all. The only things that do work, ephedra, DMAA, are no longer available. And even with those strong stimulants, you Still have to eat a clean, reduced calorie diet.
