Now, Kelly Brook has got in on the alkaline action and we've spotted a copy of the book in one of her latest Instagram snaps.
The star showed us this snap of her anti-green juice breakfast featuring cupcakes and pastries, but we couldn't help but spot a few healthy cookbooks in the background.
Honestly Healthy, by vegetarian chef Natasha Corrett and nutritional therapist Vicki Edgson, combines recipes alongside information about following the alkaline diet principles.

Honestly Healthy was a business launched by the pair which does a range of take away foods (available in Selfridges) and has developed menus for luxury hotel groups around the world.
Speaking of the Alkaline diet to Glam UK, Edgson explained her support, 'Very often, people become unwell because they are over toxic, overloaded, and the body is very highly acidic. Indigestion, bloating, abdominal pains, cramps, food intolerances, unnecessary sweating and skin problems will clear up very quickly when somebody is put on an alkaline diet.'
Chef Corrett added, 'Things that we cut out are wheat, gluten, sugar, fried sugars, cow's dairy, caffeine and alcohol. It's a much more simple way of eating. I hate being told I can't have something. So you can have pizza, pasta and brownies but they are done in an alternative, inventive way.'
Kelly has joined a whole host of celeb fans including Gwyneth Paltrow, Jennifer Aniston, Kirsten Dunst and of course VB.
Honestly Healthy: Eat with your body in mind, the alkaline way, £12.80 (hardcover) by Natasha Corrett and Vicki Edgson is available now on Amazon.co.uk
