Heston Blumenthal has revealed that he is taking the weight-loss drug Wegovy. The celebrity chef admitted his use of the drug was a “paradox” as a restaurateur, and warned that its continued use threatened to topple the food industry.

People taking weight loss drugs typically start to lose weight within a few weeks. One study, funded by Mounjaro manufacturer Eli Lilly, found that Mounjaro led to 20 per cent weight loss after 72 weeks of treatment, whereas Wegovy led to 14 per cent weight reduction.

Several new weight loss drugs are undergoing trials in the UK. These drugs will work similarly to those already available but may be administered differently (such as an oral tablet). The trials for these and subsequent approvals will not only increase market competition, but also improve patient access and choice.
