NHS doctors should be "selective" when recommending very-low calorie diets to overweight and obese patients, according to fresh guidelines.
- Very-low calorie diets should only be used when a patient has "a clinical need to lose weight quickly," like impending joint replacement surgery.
- The draft guideline also recommends that people who have undergone bariatric surgery on the NHS should have a "follow up care package" for at least two years after their operation.
- In the UK around 2.9 million people have diabetes, with around 90% of cases being type 2.
- There are also thought to be around 850,000 people with undiagnosed diabetes.
