Josie Gibson, 40, details in ‘The Josie Gibson Diet book’ the four major things she did in order to lose over 31kg in such a short space of time.

The This Morning presenter wrote: “I didn’t get a gastric bypass; I got off my big a**e, moved more, ate less, and educated myself on what I was stuffing into my body.”

This isn’t the first time Josie has talked about her weight loss in recent months, revealing last year that she made one major change following the birth of her son in 2018.

She said that she cut out refined sugars entirely, and decided to have only those which appear naturally in fruits.

Josie told the Mirror that she realised she couldn’t be entirely strict about it and had to cut herself some slack in order to fully enjoy life. She said: “So I did the six-day plan on Do The Unthinkable, which entitled me to one day off.

“Now on that one day off, I had one cheat meal – I didn’t go crazy and drink 10 bottles of wine and binge all day on food and chocolate and all the naughty things I haven’t been having, I just had my one cheat and that was it.

“So if you’ve got that one day off, don’t undo all your hard work. Just have your one cheat meal and enjoy it. Don’t have a day binge.”

Josie also said that she engaged in intermittent fasting, the act of extended periods of time without eating, in order to cut the pounds. In Josie’s case, she elected for an eight hour period where she ate nothing at all.

However, whilst intermittent fasting has been found to have some benefits, nutritionists have warned it isn’t a silver bullet for health and weight loss in general.

Writing in The Standard, nutritionist Louise Pyne said people shouldn’t be overly reliant on the practice, warning it can sometimes backfire. She explained: “While it can achieve good results for some, researchers have found that it doesn’t work for everyone.

“One intermittent fasting study, which restricted participants to intersperse daily caloric restriction with unrestricted eating actually found that participants ended up eating more on the unrestricted days in anticipation of having to fast the following day, and furthermore, they also ended up exercising less.”
