Who Katharine Jenner is

Katharine Jenner is a Registered Nutritionist who joined the Obesity Health Alliance as Director in 2022, having spent fifteen years at Consensus Action on Salt, Sugar and Health (CASSH). She led the establishment of Action on Sugar and previously served as CEO of Blood Pressure UK; she is also Interim-Chair of Sustain and Chair of the Children's Food Campaign. The Obesity Health Alliance is a coalition of more than 50 organisations working to prevent obesity-related ill-health by influencing government policy on overweight and obesity. She gave oral evidence to the House of Lords Food, Diet and Obesity Committee in February 2024 and has publicly argued that obesity policy failures stem from reliance on individual behaviour change in a food environment that works against people. She has called for mandatory food industry health reporting, restrictions on HFSS advertising, and stronger regulatory action on the food environment.

“There is a real risk that those who would benefit most are the least able to access these medicines – either at all, or as intended alongside the wraparound support needed to sustain weight loss.”

What Katharine Jenner has said

  • “The large numbers of GPs who had seen obese infants and young children is another sign we're letting children down before they even start school. If we're serious about prevention, it has to begin in the earliest years, otherwise the damage follow them through life.”

  • “With millions of people affected by preventable diseases caused by tobacco, alcohol and unhealthy food, we need stronger action from the government to match the rhetoric – including minimum unit pricing to prevent strong alcohol being sold cheaply, a levy on the profits of the tobacco industry and the implementation of mandatory policies to improve food and drink.”

  • “regaining weight after stopping treatment was not a failure of individuals, but rather reflects the reality of living in a food environment that continually pushes people towards unhealthy options.”

  • “These figures should be a wake-up call. All parents want their children to grow up healthy, yet seeing children as young as four needing specialist NHS treatment for their weight highlights just how early the drivers of poor health are taking hold.”

  • “This is a hugely popular policy, backed by parents, health professionals and the public, and a vital step towards protecting children's health. Strong evidence links high-caffeine energy drinks to anxiety, poor sleep, reduced concentration and harm to learning and wellbeing – restricting sales to children at a vital time in their life is just common sense.”
