I've been on this diet 6 weeks now and lost almost a stone. I pretty much stick to the calories although I'm doing it more by eye than counting and am more physically active although struggling to get 150 min per week. But one of the biggest things I've noticed which is less positive is that I seem to be feeling cold a lot of the time. I wondered if it's because my fat reserves are being used to fuel my body instead of insulating me. Anyone else experience this?
