Dr Michael Mosley has become a household name over the years, offering top tips and advice on all things healthy-eating - including best foods to eat and what exercises really work. The health expert is arguably best known for being the founder of the Fast 800 diet, which is a "12 week programme to support long- term weight loss and better health."

His website, of the same name, explains the diet in depth and shares a variety of rules to follow to keep you on track. The website also provides a plethora of clever hacks about various other aspects of dieting and weight loss - one being cravings.

When going on a diet, it can be hard at first to resist sneaking in a couple of sweet treats and sugary snacks. But before you know it, you've ruined your health plan. To help those with a sweet tooth, Dr Michael Mosely has explained the steps you can take to prevent cravings and what you should eat instead.

One thing you can do that may help is psychological. "As soon as you have finished the last meal of the day, brush your teeth," Mosley says. "It’ll help you to keep away from snacks and nibbles."

Another handy trick is to keep drinking water. He says: "People sometimes confuse thirst with hunger, so you can end up eating lots of extra calories when what all you really need is fluid. A hot drink on an empty stomach is also remarkably soothing." Black tea, black coffee or peppermint tea could be a good option.

Another way to steer clear of cravings is to indulge in fibrous foods. "Whole pieces of fruit do contain some sugar, but are packaged up with fibre - fibre slows the release of glucose into the bloodstream," he says, which helps you to feel fuller for longer.

"This means whole fruits are generally a better choice than tinned or dried fruits, and juices, but it’s easy to consume more than we should and crowd out room in our appetite for more beneficial foods richer in protein and phytonutrients.

"If you really do want fruit without compromising your blood sugar levels, we recommend berries and hard fruits. Apples and pears can be consumed; eat as part of your meals and stick to no more than two to three portions per day." The health expert also suggests cucumber, celery, almonds and walnuts are also good snack options.
