Celebrity Fans: Cheryl Cole, Sir Cliff Richard and Courtney Cox-Arquette are reportedly fans of this diet.
What’s it all about? This diet is completely based on pseudo-science. It claims that different nutrients are broken down in the body based on the body’s blood type.
• Blood Group A – No dairy products allowed and a vegetarian-based diet.
• Blood Group B – A more varied intake of food and the only blood group able to ‘manage’ dairy products.
• Blood Group AB – Combination of diets A and B (confused yet? Yes or no to dairy?)
• Blood Group O – High meat intake, no dairy, no wheat, no grains (think Atkins).
BDA Verdict: Blood and sweat won’t make this work! Cutting out food groups is never a good idea (unless medically advised to do so and with help making substitutions from a Dietitian). This diet could lead to significant deficiencies such as calcium. You lose weight on this diet because your calorie intake is very restricted and this diet is not sustainable in the long term.
