Little changes to your diet and exercise can also help, and different studies back up the idea that changing the time of day you eat, what you eat and how much of it can affect how much weight you lose over a period of time.
The award-winning This Morning diet man is the founder of the Fast 800 Diet, which involves fasting and eating at certain times.
So when should you eat?
What time of day should I eat to lose weight?
According to Dr Michael Mosley the best time of day to eat is before 8pm, hours before bedtime.
Mosley explained: “Try and stop eating by 8pm and then not eat anything with calories after that.”
Avoiding calories closer to when you fall asleep is important, as what you eat later “hangs around in your system for much longer”.
Dr Mosley added: “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 quite a lot of calories loaded on late at night.
“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.”
Of course, changing the time of day that you eat isn’t a problem-solver if your diet is bad and you aren’t getting enough exercise. It is best to focus on this before making those smaller changes, though sometimes every little helps.
Michael Mosley sleeping tips.
Having advised that people should avoid eating shortly before they go to sleep, Michael Mosley also has tips for helping people sleep when they are having trouble dropping off.
In a conversation with ex- BBC Breakfast presenter Dan Walker on the Newscast podcast, Dr Mosley said people should follow the “15-minute rule”.
He said: “The advice is broadly the 15 minute rule. If you are still awake after 15 minutes, get up and do something boring until you feel sleepy and then go back to bed. The rule is to associate bed with sleep and sex and nothing else. No Twitter, no TV, nothing else.”
Experts at the University of Oxford also advise this particular method of getting yourself some sleep and they said people should just estimate what a quarter of an hour is, rather than checking a watch.
They said spending time in bed awake means that “bed might become connected with being awake, frustrated or anxious about sleep”.
