No Junk food ads on television will be allowed before the 9 pm watershed from October 2025 under a new law. The UK government confirmed the final details of advertising restrictions, including a ban on paid online junk food adverts, on Tuesday (3 December). The proposed legislation is part of a broader strategy to curb childhood obesity and address rising rates of obesity-related diseases such as diabetes and heart disease. Detailed guidance on which food and drink categories will be covered by the regulations has also been published. These measures are expected to remove 7.2 billion calories per year from UK children's diets, potentially preventing around 20,000 cases of childhood obesity. Health secretary Wes Streeting emphasised the need for such preventative action, stating: "Obesity robs our kids of the best possible start in life, sets them up for a lifetime of health problems, and costs the NHS billions. "This government is taking action now to end the targeting of junk food ads at kids, across both TV and online.

The Medicines and Healthcare products Regulatory Agency (MHRA) has approved a new indication of semaglutide (Wegovy), authorising its use to reduce the risk of serious heart problems and strokes in adults who are obese or overweight. Semaglutide, a GLP-1 receptor agonist, was previously approved for use in the treatment of obesity and weight management, to be used alongside diet, physical activity and behavioural support. The latest approval establishes it as the first weight loss drug to be prescribed to prevent cardiovascular events, such as cardiovascular death, non-fatal heart attack and non-fatal stroke, in people with established cardiovascular disease and a Body Mass Index (BMI) higher or equal to 27 kg/m2. Novo Nordisk, the manufacturer of Wegovy, received this authorisation on 23 July following compelling evidence from a recent post-approval clinical study involving over 17,600 participants. The study demonstrated that Wegovy, administered at a dose of 2.4 mg once weekly via subcutaneous injection for up to five years, significantly lowers the incidence of major adverse cardiovascular events (MACE) by 20 per cent compared to a placebo.

Part of a raft of National Health Services (NHS) measures which aim to support people to prevent or reduce incidence of type 2 diabetes and obesity, the NHS Digital Weight Management Programme has emerged as a beacon of success in the battle against obesity, with a recent study showcasing its effectiveness in aiding weight loss among participants. According to research published in The Obesity Journal, the programme has garnered significant traction, with over 63,000 individuals referred in its inaugural year. Encouragingly, half of those referred opted to enroll in the service, highlighting its appeal and accessibility. Among the 14,000 participants who completed the 12-week programme between April 2021 and March 2022, a notable average weight loss of 3.9kg (equivalent to 8.59lbs) was achieved. Even among those who did not complete the programme, an average weight loss of 2.2kg (approximately 4.85lbs) was observed.

Researchers at the University of Oxford have received a grant of up to £600,000 from Cancer Research UK to develop the world's first vaccine to prevent ovarian cancer. Named OvarianVax, the innovative vaccine aims to train the immune system to recognise and attack the earliest stages of ovarian cancer. Ovarian cancer is the sixth most common cancer among women in the UK, with approximately 7,500 new cases diagnosed annually-equating to about 21 cases each day. It is also a leading cause of cancer-related deaths in women, with around 4,100 deaths each year, accounting for five per cent of all cancer deaths in UK females. Projections suggest that by 2038-2040, there could be around 9,400 new cases of ovarian cancer annually in the UK. Several factors influence a person's risk of developing ovarian cancer, including age, genetics, hormone replacement therapy (HRT), smoking, asbestos exposure, medical conditions such as endometriosis or diabetes, and obesity. Faults in the inherited genes, particularly BRCA1 and BRCA2, are linked to a higher risk of ovarian cancer, contributing to 5-15 per cent of cases.
