In 2016, we helped Cancer Research UK show that a 20% sugar-sweetened beverage tax could stop 3.7 million people from becoming obese by 2025. That’s a 5% decrease in national obesity levels. It would save about £10 million in direct NHS healthcare costs in the year 2025 alone.
In 2018, we worked with Public Health England, Imperial College School of Public Health and Imperial College Business School. Together, we created a new tool that helps local authorities estimate how much they could save the NHS by taking action on air pollution.
We looked forward to 2035 to see what kind of impact social inequality will have on obesity. We found that by then, UK people aged 16 and older working in routine or manual jobs will have the highest levels of, and greatest increases in, obesity.
Our REBALANCE project, a collaboration with the University of Oxford, analysed the impact of different weight management programmes on severely obese over-18 year olds. That helped the NHS assess and understand the long-term cost-effectiveness of these programs, then choose which one to go ahead with.
