I just looked on Calculator.net and it confirmed something I have really always known. At my size, to lose 1 pound a week I have to eat fewer than 1100 calories a day and to lose 2 pounds a week (which Weight Watchers promotes as ideal) I would have to eat fewer than 600 calories a day. Maths told me that, but it is a depressing thought. I find it isn't true at the beginning of a diet when I have recently put on a lot of weight suddenly, (like Christmas and holidays), but by the third week, yes, it is true. The only other thing I can do to change it is use up a lot of calories by exercising, particularly running, but that is more appealing when the weather is better.
