but IMO 1200 calories is to few calories for a grown man.
My BMR (basal metabolic rate) is 1750 calories. Thats the amount of calories I need to consume per day, based on my height, weight and age, for my body to maintain a steady weight. In order to lose 1 lb a week, you need to create a deficit of 3500 calories, so thats 500 calories a day that I need to not consume or burn off with exercise. I know it sounds low, but when you get used to doing it, its not too bad.
