People looking for diet and weight loss results have been advised to maximise food that are rich in fibre and protein.
That's the advice from Michael Mosley, a TV presenter and former doctor known as the creator of the 5:2 diet in which people dramatically cut their calorie intake two days a week.
The diet guru shared his advice for the best foods to keep slimmers feel fuller for longer.
He recommends people eat food high in fibre and protein that enable them from getting hungry during the day, The Express reported.
These are the best foods to eat because snacks that are high in sugars and carbs will raise dieters' sugar levels, meaning they will "crash and then get hungry", according to Dr Mosley.
Mosley is also the author of The Fast 800 diet that involves intermittent fasting, time-restricted eating, and following the Mediterranean diet.
He said: "The best way to prevent hunger when you're intermittent fasting is to use something like a meal replacement shake.
"Follow The Fast 800 programme, because it has been very carefully calibrated to ensure it gives you the maximum nutrients and the maximum amount of fibre and protein."
Mosley continued: "I find that if you're eating something which has plenty of fibre in it and plenty of nutrients, I really don't get hungry hardly at all."
The 5:2 diet creator therefore recommended eating something healthy like a handful of nuts.
He added: "That really takes the edge away.
"It is important to have decent amounts of protein, by which I mean around 50 grams a day.
Foods that contain high amounts of protein are meat and fish, but also legumes, vegetables, lentils, and other ingredients that are included in the Mediterranean diet, according to Mosley.
He went on to explain that meal replacement shakes also contain a lot of protein, saying that The Fast 800 diet involves "meal replacement shakes which are very rich in protein, and we're also aiming to produce protein boosters, to help people who might otherwise struggle with it".
Mosley continued: "The reason for protein is you need it for your muscle. You need it for all sorts of essential metabolic processes.
"And also because when you consume it, it's digested slower by your body so you don't get the same sort of peaks."
Another of Mosley's top tips while intermittent fasting is to eat earlier, "say 7pm to 7:30pm".
Mosley said: "Try and stop eating by 8pm, and then not eat anything with calories after that.
"The temptation is to eat cheese and biscuits late into the night.
"Although the idea that cheese will give you nightmares is a complete and utter myth, it will obviously be sort of quite a lot of calories loaded on late at night."
He added: "And we know the fat and sugar you eat later at night, it just hangs around in your system for much, much longer because your body is just closed down for night.
"Your digestive process will be closing down, and it really will not appreciate that late night snack."
