This sounds like a great idea for those with type 2 diabetes. The NHS can't roll it out fast enough.

Tens of thousands more people in England living with type 2 diabetes could be offered an 800-calorie-a-day “soup and shake” diet after research found almost one in three on the groundbreaking NHS scheme permanently wiped out their disease.
Patients are given low-calorie meal replacement products such as soups, milkshakes and snack bars for three months, triggering rapid weight loss, before getting support to reintroduce normal food into their diet.
Currently, 10,000 people a year can access the scheme but “brilliant” results showing “life-changing benefits” among participants have prompted NHS leaders to consider expanding the programme.
Some who took up the diet lost as much as 17.4kg (38lbs). Almost a third put their type 2 diabetes in remission, according to a paper published in the Lancet Diabetes and Endocrinology journal.
