Data were used to estimate changes in energy (kcal, 1 kcal=4.18 kJ=0.00418 MJ) purchase associated with a 20% price increase in high sugar snacks. Data for 2544 adults from waves 5 to 8 of the National Diet and Nutrition Survey (2012-16) were used to estimate resulting changes in BMI and prevalence of obesity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Main outcome measures<\/jats:title><jats:p>The effect on per person take home energy purchases of a 20% price increase for three categories of high sugar snacks: confectionery (including chocolate), biscuits, and cakes. Health outcomes resulting from the price increase were measured as changes in weight, BMI (not overweight (BMI &lt;25), overweight (BMI \u226525 and &lt;30), and obese (BMI \u226530)), and prevalence of obesity. Results were stratified by household income and BMI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For income groups combined, the average reduction in energy consumption for a 20% price increase in high sugar snacks was estimated to be 8.9\u00d710<jats:sup>3<\/jats:sup>kcal (95% confidence interval \u221213.1\u00d710<jats:sup>3<\/jats:sup>to \u22124.2\u00d710<jats:sup>3<\/jats:sup>kcal). Using a static weight loss model, BMI was estimated to decrease by 0.53 (95% confidence interval \u22121.01 to \u22120.06) on average across all categories and income groups. This change could reduce the UK prevalence of obesity by 2.7 percentage points (95% confidence interval \u22123.7 to \u22121.7 percentage points) after one year. The impact of a 20% price increase in high sugar snacks on energy purchase was largest in low income households classified as obese and smallest in high income households classified as not overweight.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Increasing the price of high sugar snacks by 20% could reduce energy intake, BMI, and prevalence of obesity.
