Hi Ola. Here you can buy ketostix. They are available in drug stores. You pee on them and they measure the amount of ketones in your urine.

Are you working out at all? That really helps you get more of a toned look.

I am also fairly close to my ideal weight and trying to figure out how to get the last bit off. I would not suggest making yourself go hungry. Do some research, try a few different things and tweak the diet until something works for you. It may help you if you start a journal where you can track what you're eating.
