I have reached week 12 of the NHS plan I have lost a total of one stone one pound but as I posted yesterday I didn't lose last week. My aim wasn't to get to a certain weight but to reach a healthy bmi and to get rid of my dangerous "belly fat" which is going but there is still some there. I have just read that if in conjunction with calorie control you take a calcium supplement together with a vitamin D supplement it speeds up the metabolism and in particular helps reduce visceral fat. Is this the answer to my prayers? or is just going to make me lose pounds out of my purse! Has anybody else heard this or even tried it? Do you think it's worth trying?
