Don’t use artificial sweeteners for weight loss, WHO says
- Such diet products probably don’t help reduce body fat in the long term and instead are linked with a higher risk of diabetes and heart disease
- The new guidelines apply to all non-sugar sweeteners, including stevia derivatives and sucralose

Artificial sweeteners may not help people lose weight, the World Health Organization has said in new guidelines that warned against products like diet sodas.
The WHO’s advice is based on a scientific review found products containing aspartame and stevia – often marketed as diet foods – probably do not help reduce body fat in the long term.
“People should reduce the sweetness of the diet altogether,” Francesco Branca, WHO director for nutrition and food safety, said on Monday.
Artificial sweeteners were also linked with higher risk of developing type 2 diabetes and cardiovascular disease, as well as of dying, according to the WHO.
The new guidance applies to all non-sugar sweeteners, including stevia derivatives and sucralose. Such products have become widely used and are commonly added to processed foods and beverages, like diet soda, or sold on their own.
