In March 2023, the NHS announced it would make Wegovy, a drug made by Danish firm Novo Nordisk, available on prescription to thousands of obese Brits.

It contains the drug semaglutide, which is said to have helped reality star Kim Kardashian and Twitter boss Elon Musk lose weight.

Wegovy, which helped a third of people reduce their weight by 20 per cent in trials, is now available from pharmacies like Boots.

How do they work?

The jabs work by suppressing your appetite, making you eat less calories and therefore lose weight.

To do this, an ingredient found in the fat-busting drug, known as Semaglutide, mimics the role of a natural hormone, called GLP-1.

GLP-1 is part of the signalling pathway that tells your body you have eaten, and prepares it to use the energy that comes from your food.
