I don't know if you are talking about slimming capsules. I have eaten the OB protein slimming essence in Newcastle, USA. When I eat it, I am always thirsty. I have been drinking water, so I don't feel hungry. I feel full after eating a little. I lost 4 pounds in the first week, but I stopped eating and was able to eat again. I think Oster should be like this, too. They are all OB proteins. My suggestion is that you'd better not eat it.
