According to foodfocus I USE 2051 calories a day to keep myself the weight I am and in order to lose 2 lb a week I have to consume 1051 calories every day.
Now I've managed it this week (actually I've managed to keep to the calories, I've no idea about the weight loss yet) by being completely scrupulous but I still think it's quite hard.
It is hard isn't it? I seriously take my hat off to anyone who manages that for months and months. How on earth do people manage to eat half the food they were eating before - that is some serious willpower.
Well done to all those who do.
