Mick Collins, 58, who is a cheese seller in Weston-super-Mare in Somerset, said he thought he’d continue to inject once weekly instead of possibly having to take a pill every day.

Collins is on a two-year NHS programme for weight loss using Mounjaro, and has gone from 17 stone down to 14 stone and four pounds.

“I think pills would get annoying and I might forget to do it,” he said.

“I’m fine with sticking a needle in my stomach, it doesn’t hurt and you really don’t know you’ve done it.”

Collins added it was “nonsense” that some men felt embarrassed taking weight loss drugs.

“Look, if the nurse tells you are in diabetes type two range and if you don’t lose the weight you might lose a finger, you lose the weight – no contest.

“On top of the drugs I’ve done a lot of hard work, jogging and getting healthy.

“The best moment I’ve had recently was fitting into a Harlequins [rugby] shirt I’d not been able to wear for 25 years.”
