Last week i decided to go on a diet. I am 5,5 and when I started I was 130 pounds. That is seen as a healthy weight but I still looked a bit chubby around my thighs and bum. So I started cutting down on junkfood and snacking. I eat three meals a day and I never feel hungry. I stepped on the scales today (it's been a week since I started the diet) and I now weigh 116! That's almost a stone! I don't think I should be losing that much. I feel constantly dizzy and tired and just horrible..is it because I'm losing weight too fast?
