7th December 2017 – Think 'diet'. Now think, 'celebrity'. Whenever a new diet is promoted to help lose weight or boost your health, it's usually a dead cert there it will have some sort of celebrity backing or endorsement.

Each year, the British Dietetic Association (BDA) releases its top picks of celebrity diets it says we should ignore in the New Year – the traditional time when weight loss is uppermost in our minds as we try to bounce back from Christmas overload.

This year the BDA warns that among the faddy, the factually incorrect and the downright bizarre, some diets out there are actually dangerous.

So, are you looking for a diet that will lead to a new, healthier, more attractive and energetic you? Then here are the 5 celebrity diets to avoid in 2018.

1. Raw vegan

What's it all about? This is a plant-based diet that involves no cooking.

Fans of this diet consider food to be raw if it has not been heated over 40 to 48 degrees C. Foods should not be refined, pasteurised, treated with pesticides or processed in any way.

The raw vegan diet has been promoted as a cure for obesity and other disease.

Celebrity endorsements? Gwyneth Paltrow, Megan Fox and Sting.

A carefully planned vegan diet combined with supplements such as vitamin B12 and vitamin D can be healthy, says the BDA. However, it won't guarantee weight loss. A vegan cake is still a cake, and will probably contain the same calories as any other cake.

Also, while some foods are good to have raw, others, such as carrots, are more nutritious cooked. And anyone following this diet wouldn't be able to eat some foods, such as potatoes.

Raw food can be time consuming to prepare and will be hard to find when you eat out.

The raw vegan diet will be "raw-ther a challenge", according to dietitians. It may not damage your health in the short-term but could in the long-term if not balanced.

2. Alkaline

What is it? Enthusiasts believe that eating more alkaline and less acidic foods will help change the pH balance of their blood and reduce health risks. Some wrongly claim it can treat cancer and that 'acidic' foods cause osteoporosis.

Which celebrities endorse this approach? Tom Brady, the Duchess of York and – yes, again – Gwyneth Paltrow.

What do BDA experts make of it? Basically, that it is based on a misunderstanding of human physiology.

People should be encouraged to eat more fresh vegetables but there is no correlation between the pH of your food and the pH of your blood.

Experts say there's a good reason why you wouldn't want to change the pH of your blood because unless it stays within specific parameters – which the human body is capable of maintaining on its own – you could become ill quickly and die.

What's the bottom line? It's "nonsense" and an "alka-lie", according to the BDA.
