Weight loss injections are being prescribed to hundreds of UK military personnel, with figures showing a more than threefold increase in their use. In 2025, 240 service members were given Mounjaro or Wegovy jabs, up from 73 in 2024.
Of those receiving the injections, 128 were in the Army, 58 in the RAF, and 54 in the Navy. The majority (194) were lower ranks, while 46 were officers. Separate Ministry of Defence data reveals hundreds of personnel fail annual fitness tests, and a small number are discharged each year due to obesity, with some weighing over 26 stone.
Official BMI records show over 11,000 soldiers, 4,300 sailors, and 3,900 aircrew are classified as obese. However, the military argues BMI is not always accurate, as many personnel have high muscle mass. Some individuals with waist measurements exceeding 55 inches have also been offered liposuction.
Former British Military Intelligence Colonel Philip Ingram commented: “It is good to see the military using all available tools to get personnel fit again. It is more cost effective to fix trained personnel than replace them.”
An MoD spokesperson said: “Only a small proportion of the Armed Forces are affected by obesity. World-class support is provided, and weight loss drugs may be considered on a case-by-case basis as part of a lifestyle programme.”
