Once upon a far less skinny time...
"Cheerleaders. It's all their fault. As teenagers, we sat in the stands with the other non-size twos watching "them" bounce around the field in their miniskirts in colours designed to make you look fat. Even their moves shouted, "I'm zero percent body fat". So we repeat: Cheerleaders! It started with you."

The non-diet diet book
"The Black Book of Hollywood Diet Secrets provides tips that you can easily incorporate into your lifestyle. For example, make like supermodel Heidi Klum and eat salad with vinegar on it before going out to dinner. Vinegar kills hunger so you'll never attack the bread basket again."

Halle's help
"I got tough when I was a little girl", says Halle Berry. "You have to tell yourself that you can do it. I go for weeks where I don't go out or I'm travelling and I can't work out. It's hard to get back into it but once you start the endorphins your body releases will allow you to be excited about doing it again."

A-list lingo
"Hollywood speak: Friend fat - when you're on a diet and your friends eat, eat, eat. You eat to make them happy and thus gain friend fat. For example, 'I was so thin until I started hanging out with Britney, but then I gained some friend fat.'"

All about Eva
"I work out three to four times a week. My trainer kicks my ass", moans Eva Longoria. "I live in the Hollywood hills, so it's very inclined. We do lunges while walking up the hill and then do squats up the next. I do this early in the morning, and the entire time I'm thinking, 'why oh why did I leave my pillow?"

Party On!
"Paris and Lindsay seem to be at parties every night. How can they do it? We go to a party once every six months and gain ten pounds from two greasy shrimp puffs. A top Hollywood nutritionist gave us a tip: Before the party eat a piece of low fat cheese, it takes the edge off your appetite."

A change is as good as a rest
"I love to work out", says Catherine Zeta-Jones. "I'm always mixing it up a little bit between walking , working out in a gym, and swimming. I don't do any routine two days in a row, but I do make sure to work out five times a week. That's my biggest tip to stop you getting bored and losing motivation."

Weighty wake-up call
"If you want to lose weight it's as easy as catching some Zs. A study at the University of Chicago discovered that the key to losing pounds is being in deep REM sleep between midnight and two a.m which is when the production of human growth hormones (which burn fat and build muscle) really gets going."

Diet joke
"Jessica Alba told us to put down our can of diet soda immediately or we would be booked for an extreme diet violation. Sit down for this news: Studies show that every can of diet soda consumed daily nearly doubles your risk of being overweight!"

Cocoa loco
"If you want a body like Hilary Swank , eat only these snacks: low-fat yoghurt, string cheese, nuts, fruit and 70 percent dark semisweet chocolate. The chocolate will help you burn fat, increase lean muscle mass, improve your skin and hair and flatten your stomach."
