I don't eat two days a week. And people are fascinated by it, but it works. If you cut two days of food out of your life you will lose weight.

Never order food in excess of your body weight.

I go to Costco every weekend. It's my favorite part of the week.

On Monday and Thursday, I eat fewer than 500 calories a day; then I eat like a pig for the other five days. You 'surprise' the body: keep it guessing. I got the idea from a BBC documentary about this Indian man who seemed about 138 years old and said his secret was severe calorie restriction.

I try to be healthy. I train three days a week with a trainer. But I do like to eat, clearly. And I do eat dessert every day. If I cut that out, yes, I would lose weight.

The best way to lose weight is to close your mouth - something very difficult for a politician. Or watch your food - just watch it, don't eat it.
