Post-Ryan Reynolds (when he went on to marry Scarlett in record time!), Alanis Morissette has dropped a massive nine kilos! The secret to her break-up diet? The 35-year-old, former self-confessed yo-yo dieter has switched meat for a plant and fruit-based vegan diet. The singer joins a growing list of celebs – including Natalie Portman and Pamela Anderson – who swear by a meat-free diet to keep their bods red-carpet readd...

Slim with salad

Alanis admits going green wasn’t easy saying, “It was a big lifestyle change for me.” But the singer – who now starts her day with a spinach and banana smoothie, followed by a kale salad, snacking on grapefruit – says she hasn’t looked back.

“I’m eating like an adult rather than like a seven-year-old at a candy store,” she says. Adding, “Now, around food, I can be trusted.”

Why go green?

The current A-list trend towards animal-free living comes amid claims from climate change experts that meat-eaters need to mend their carnivorous ways – “Meat is a wasteful use of water and creates a lot of greenhouse gases,” says eco expert Lord Stern. “It puts enormous pressure on the world’s resources. A vegetarian diet is better.”

Posh and Kylie sign up

New members to the celeb veggie club have been recruited thanks to the Skinny B**** phenomenon currently sweeping T’town. The diet book – written by former Ford model agent Rory Freedman and ex-model Kim Barnouin, and sold at plush LA store Kitson – bans animal products and counts Kylie and Victoria Beckham among its fans.

Top tips for going veggie

Go slow Don’t go cold turkey (or should that be cold soya?) immediately, or you’ll be less likely to stick it out.

Get your vits Replace the iron and vitamin B you usually get in meat with plenty of B-rich foods like green leafy vegetables, seaweeds and yeast (such as Marmite) in sauces.

Lay off the cheese Dairy farming can also be environmentally damaging, so investigate vegan options, made from soy or nuts.
