He adds: “Often, the best solution is to lose weight. When I went on the 5: 2 diet in 2012, and lost 9 kg, I also lost an inch of fat on my neck and the snoring stopped. Completely.”
For those who need to lose a lot of weight quickly, the special diet is based on consuming 800 calories a day for 12 weeks.
The NHS classifies people with a BMI (body mass index) over 40 as “severely obese” and they may benefit most from restricted calorie intake.
Alternatively, for those who have less weight to change, the 5: 2 plan focuses on healthy eating for five days and two days on an empty stomach (without eating).
