And the thing is, I'm not going to 'go on a diet' - that is, alter what I eat. It's bound to fail in the long run. You can lose the weight all right, but it's sure to go on again sooner or later. Not if your weakness is for several packets of crisps and a couple of Mars bars every day, the thing to do there is just stop eating them. But if you've got a healthy and sensible diet, there's very little to give up.
So I'm going to eat anything I want, but a lot less of it. Small portions, never clear my plate unless I'm the one who's chosen the amount of food in the first place. And if I'm still a bit hungry, that's no bad thing. Think of being hungry as the body using fat.
I'm not giving up cheese again. Life without cheese isn't worth living.
