With the 6 week break fast approaching, I've decided now is the time to lose some weight. Had a weigh in on Monday and I've a mass of 19st12lb. At only 5"11 this is a problem. Been down the gym yesterday and today with a mate to make sure I don't pussy out, and I'm wrecked. I'm stopping all bar a weekly takeaway and also cutting back on portion sizes. My goal is to lose a stone in a month and also to be under 18 stone by the time I go back to work in September. Is this realistic?
