Almost 18,000 members of the British armed forces are clinically obese, according to latest figures.
The statistics show that 398 troops have type 2 diabetes, 160 personnel have been prescribed diet pills and 16 given liposuction.
The data was supplied by the Ministry of Defence to the Mail on Sunday in response to a Freedom of Information (FoI) request.
As of July 2018, there were 8,662 obese soldiers in the Army, 4,666 in the Royal Navy and 4,274 in the Royal Air Force.

The figures also show that more than 30,000 troops are considered overweight, based on the body composition measure (BCM).
The MoD uses BCM, which comprises body mass index (BMI) and waist circumference, as the BMI does not differentiate between muscle mass and body fat.
An MoD spokeswoman said:
"Our personnel are required to pass our challenging fitness tests, and those who do not pass are provided with diet and fitness support, in order to reach and maintain a healthy weight."
The military said if personnel fail a fitness test, they are put on a targeted programme to help them back to the required levels.
