The use of weight loss jabs has nearly tripled over the past two years, knocking millions off Britain's grocery bills as users ditch junk food.

New figures reveal that 6.3 per cent of households now have at least one user of the appetite-suppressing drugs, compared to 2.3 per cent in 2024.

The ascent of the drugs - sold under brand names Mounjaro and Wegovy in the UK - threatens to have big implications for food and drink businesses.

The drugs are taken as a weekly injection and trick the body into thinking it is full, meaning less ‘food noise’ and fewer cravings.

With 1.9million Britons using the jabs, spending on groceries has declined by a total of £780m over the past year, according to researchers at Worldpanel by Numerator. It means that households with one user of a weight loss jab are spending £418 less than non-user households.
