WHO Advises Against Sweeteners for Weight Control in 2023 Guideline

Summary
WHO’s 2023 guideline says non-sugar sweeteners should not be used to achieve weight control or reduce noncommunicable-disease risk, despite their widespread use as sugar substitutes.
The advice reflects evidence that sweeteners are not a standalone fix and should not replace broader dietary changes centered on lower sugar, salt and saturated fat and higher fibre intake.
UK diet bodies updated their joint position after the guideline, saying sweeteners can still help heavy sugary-drink consumers—especially people at risk of type 2 diabetes—if used only as a step away from sweet tastes.
The warning comes as sugar intake remains high: WHO and the American Heart Association cap added sugar at 10% of calories, while the UK advises 5%, yet Britons consume about twice that level.
Sugary drinks remain the main concern because they deliver large amounts quickly and are linked to tooth decay, obesity, type 2 diabetes and cardiovascular risks, making water the preferred alternative.
