He adds: “The best solution is often to lose weight. When I put myself on the 5:2 diet, back in 2012, and lost 20lb (9kg), I also lost an inch of fat around my neck, and the snoring stopped completely.”
For those who need to lose a lot of weight rapidly, the special diet is based on consuming 800 calories per day for 12 weeks.
The NHS classifies people with BMIs (body mass index) over 40 as “severly obese”, and they may benefit the most from restricted calorie intake.
Alternatively, for those who have less weight to shift, the 5:2 plan focuses on healthy eating for five days and two days of fasting (not eating).
