WHO advises against using artificial sweeteners for weight loss.

The World Health Organization (WHO) has issued new guidance advising people looking to lose weight to avoid using artificial sweeteners, as they do not confer any long-term benefit in reducing body fat in adults or children and may have potential undesirable effects, such as an increased risk of type 2 diabetes, cardiovascular diseases, and mortality in adults. WHO recommends reducing the sweetness of the diet altogether, starting early in life, to improve health. The recommendation applies to all people except individuals with pre-existing diabetes.
