If so have you liked them and have you actually lost any weight from them? Please let me know.

Read the fine print. There are healthy ways to lose weight - and your body needs fat just not the wrong kinds.
I learned to eat healthy (and not diet) with Perfect Body Shape. Even if Alli works for you (in that it helps you lose weight) you will gain it back. Only lifestyle changes will help you lose and keep it off. And Perfect Body Shape's program is guaranteed!

Do they contain Caffeine or L-carnitine? These products are often the main constituents in thermogenic diet pills.
I've been taking vitamin B supplements which are meant to induce metabolism... anyway they are not harmful and I sort of feel healthier when I take them than when I dont. Ive tried L-carnitine on its own.. it sort of makes you sweat a lot more during exercise... and I think caffeine helps too... http://answers.yahoo.com/question/index...
Mybe these products just reduce body water... bodybuilding champions use thermogenics to reduce their % body water just prior to competition.
But I think more importantly, all of these pills give you added incentive to stick to your meal and exercise plan. Meal and exercise plans form the essential ingredient for any fat reduction.
