I wouldn't use them. I got a free sample and they really don't work anyway. But considering they are supposed to up your metabolism by making your stomach acid kick in etc I would say that it would be a no-no. I tried using one whilst on LT (I love being a guinea-pig) and I felt dizzy all day and this was after being in ketosis for 2 weeks. Once I had taken it off and everything settled down I was fine.
oh right ok,well i know that seaweed is an appetite suppressant 'however you spell it' i have natural slimming pills that contain it, thought it was more for when u eat food though,cant see what difference it would make during tfr, i am taking hoodia capsules at the moment and i feel that these help me with hunger when i take them one hour before i eat, they help you to feel full but again would only be advised when taking with food. xxxx
Don't bother. I tried them and I looked up all the ingredients annd while they all have the fat burning and appetite suppressing qualities they claim to have when taken orally there is no evidence that they are effective when absorbed through the skin. Make sure you cancel that subscription with them ASAP
