From the baby food (Reese Witherspoon), to the Dukan (Jennifer Lopez) and even the ‘dirty keto’, celebrities are no strangers to a faddy diet.

And Hailey Baldwin, we mean Bieber, is no different. The actress who recently tied the knot with beau Justin Bieber revealed recently that she follows an eating regime known as the ‘Blood Type Diet.’

“I do eat meat, but I try to stick to lighter meat like chicken and turkey – I have trouble with my iron levels so I have to eat meat and couldn’t be veggie,” she told Women’s Health

“But I do eat by the blood type diet as I think it makes a lot of sense and a difference when you really stick to it.”

But what is the blood type diet and how does it differ from all the other A-list diet plans?

What is the blood type diet?

“Embarking on the blood type diet means following a diet which has been specifically designed for your blood group,” explains David Wiener, the Nutrition Specialist for fitness app Freeletics (www.freeletics.com).

The creator of the Bloody Type Diet, Dr Peter D’Adamo claims that it can help you to lose weight, feel healthier and also lower the risk of a range of diseases.

“The premise behind the diet, is that your blood group determines how our body processes and breaks down different nutrients, and that each blood group has it’s own, unique antigen marker (the way the body recognises something as being new to it), and this marker can react with certain foods, which could result in a range of health issues,” David continues.

Can it help you lose weight?

By following a diet, which has been designed for your blood type, it is believed that your body will digest and absorb food more efficiently, helping you to reap the nutritional benefits and also lose weight.

What foods should you eat/avoid?

According to David the foods you should eat/avoid are based on the four main blood types, O, A, B and AB.

“Blood Type O is advised to eat a high protein diet which is rich in lean meats, fish and vegetables, they are advised to avoid grains, dairy and legumes,” he explains.

“Type A is advised to follow a meat free diet, instead opting for vegetables, fruit, legumes and whole grains.

“Type B is advised to avoid corn, wheat, chicken and peanuts, instead choosing green vegetables, eggs and low fat dairy products.

“Type AB is advised to eat a diet rich in seafood, dairy and green vegetables.”

What are the benefits of the diet?

David says that the pros of following this diet are limited. “But the fact it pushes users to avoid heavily processed foods and sugar laden foods means that as a result you will feel better as you’ll undoubtedly be eating healthier foods which are richer in vitamins and minerals,” he says.

“The blood type diet also advocates that followers should exercise regularly (although this too is dependent on your blood type), and this too will benefit your health and wellbeing,” he adds.

“Those with an O type should partake in vigorous aerobic exercise, while A’s should stick to lower intensity activities such as yoga. B blood type should try activities which incorporate mental components such as swimming and hiking, and AB’s should include a real mix of activities.”

The cons of the blood type diet

Some experts believe that the bloody type diet is based on pseudo-science, which lacks any scientific basis.

“This for me is one of the biggest no, no’s,” David explains. “There is evidence that people feel better after following the diet, but that would be true of any diet which advises health eating, an increased intake of vegetables, as well as cutting out refined grains, processed foods, caffeine and alcohol,” he says.

And David also believes there are limitations to following the diet.

“The blood type diet can be very restrictive, and whilst the creator has clearly listed the foods you should cut out based on blood type, there isn’t a long list of substitutions which could result in people becoming deficient in vital vitamins and minerals, causing fatigue, and in extreme cases malnourishment,” he explains.

“Also, because each blood type calls for different meal plans, shopping, and food prep, cooking family meals or eating out can be very difficult.”

Plus not everyone knows their bloody type. “So if you do decide to give this a go, you’ll need to go to some lengths to find out what it is.”

Should we give it a go?

The jury’s out! There are benefits to reducing your sugar intake, eating less processed foods and upping the fruit and veg, but on the other hand the diet is pretty restrictive, without offering many substitutes.

Of course if you’re thinking of trying it out you should consult your GP or other health or nutritional professional before embarking on a drastic change to your diet.
