Really works well, I was 9st 6lb 11days ago now 9st 1lb and can see a difference in my shape. It suppresses my appetite and also must burn fat as my other half says my breath smells but this is a good sign for ketones n fat burning. I don't feel the need to snack and also my portion sizes have gone less than half the size and I'm full. Will buy again when running out. Also have plenty of energy, usually have no energy on lack of food.
