When it comes to fast weight loss, Michael Mosley has plenty of advice.
And one of his unusual tips comes down to favouring some fruit over others.
The presenter and creator of the 5:2 and Fast 800 diets is a fan of Mediterranean diets and intermittent fasting. One key part of his philosophy is following a low-calorie, high-protein, low-sugar diet.
The former doctor is guided by his own weight loss journey after having lost 1.4 stone (8.9 kg or almost 20 lbs) and 'reversed' his diabetes by changing up his diet and exercise, the Express reports.
In his Channel 4 programme, Lose a Stone in 21 days, he guided five volunteers on a rapid weight loss regimen.
Read on for Michael's diet advice, which includes swapping 'super sweet' fruits for alternatives and the snacks dieters should eat.
Michael began: "Your waist should measure no more than half your height. Too much belly fat leads to increased risk of certain cancers, heart disease and Type 2 diabetes."
He suggested that if people do not take steps to combat this, "it can take years off your life."
The expert provided his top tips on losing belly fat fast.
On the Fast 800 website, Michael and his team compiled a list of foods that dieters can eat to lose weight fast, before moving onto a Mediterranean diet, which he described as a "way of life".
On the website, it recommended that dieters start their day off with eggs, as they are low calorie - around 63 calories in a medium sized egg.
Slimmers should ramp up their protein intake, consuming foods such as oily fish, prawns, chicken and turkey.
For meat-free eaters, beans - particularly edamame - dairy, nuts and seeds can provide adequate protein.
Dieters should also stock up on healthy vegetables, the more colourful and varied the better.
And Michael far from bans dieters from eating fats.
Nuts have a high fat content but are also rich in proteins, minerals and vitamins.
Full-fat yoghurt is also recommended, and can be enjoyed with a handful of berries.
However, in order to lose up to a stone in three weeks, some foods must be limited or cut out all together.
Michael suggested banning super sweet fruits such as mango, pineapple and melon, opting for berries instead.
And when craving treats such as ice cream, chocolate or cake, the expert recommended that dieters indulge in a square of dark chocolate instead.
Snacks on the whole should be avoided, but if a slimmer must eat between meals, they should go for things like nuts, seeds, a sliver of cheese or non-starchy vegetables.
On Lose a Stone in 21 days, some of Michael's case studies lost weight by trying low-carb versions of their favourite foods - including takeaways.
While the steps are there to follow, rapid weight loss is not always easy.
One of Michael's most important top tips is to stay accountable.
"All the weight loss studies show that the people who keep it off are accountable to someone or something."
