Weight-loss jabs suspected of fuelling dip in grocery volumes

• UK grocery volumes experienced their first year-on-year decline in 2025, falling by 0.4 per cent over the past four weeks, alongside 4.7 per cent grocery price inflation.
• Data analysts Kantar suggest that the growing use of GLP-1 weight loss drugs may be contributing to changing shopping habits.
• Currently, 4 per cent of British households include a GLP-1 user, nearly double last year, with users indicating plans to reduce purchases of items like chocolates and crisps.
• Despite the drop in grocery volumes, take-home grocery sales increased by 4.1 per cent, and supermarket footfall reached a five-year high.
• The NHS recently began a mass rollout of the weight loss injection Mounjaro, allowing GPs to prescribe it to severely obese individuals with other health complications.
