What's it all about? Well, the idea is to shun all processed foods and eat only so-called 'clean' foods. That means chucking out the refined sugar, cooking from scratch, and choosing foods in their natural state. Purists go a step further and cut out gluten, grains, dairy, and even in some cases encourage a raw-food diet.
Apparently, Australian model Miranda Kerr and American actress Jessica Alba are fans of this technique. So too are cookery writers, the Hemsley sisters, Jasmine and Melissa, and fellow food writer, 'Deliciously Ella'.
The BDA's verdict is that we'd all be better off if we applied the word 'clean' to kitchen surfaces and not what we eat. "Whilst it is beneficial to reduce refined sugar and limit processed food intake, the idea of foods being 'clean' and 'dirty' is concerning," it says. "In some circumstances this way of thinking is a prelude to 'Orthorexia Nervosa' – an obsession with foods that the individual considers to be healthy, and elimination of any food that is deemed unhealthy.”
Pills are on sale that claim to stop some fat we eat being absorbed into the body. Some manufacturers say their products can actually 'melt' fat, while others claim their pills supress appetite or boost the body's metabolism to burn off calories.
Kim Kardashian and The Only Way Is Essex star, Sam Faier, have reportedly used diet pills to try to lose weight.
The BDA says people should be warned of a huge rise in the number of so-called diet pills being sold on the internet, and that some of these products are not only unregulated but could prove fatal if they contain substances not licenced for human consumption, such as pesticides.
"Diet pills should never be taken without first consulting your GP, pharmacist or dietitian as even regulated weight loss medicines on prescription can have nasty side effects including diarrhoea," it cautions.
