The Claim
Replacing sugar with low-calorie sweeteners in the diet causes a reduction in body weight by an average of 1.06 kg and decreases energy intake in adults, with greater weight loss observed when a larger amount of sugar is displaced, demonstrating that low-calorie sweeteners are effective for weight management only when they substitute caloric sugars.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you swap sugary foods and drinks for ones with artificial sweeteners, you might lose about 1 kg and eat fewer calories—especially if you cut out a lot of sugar. But this only works if you’re replacing sugar, not just adding sweeteners on top.

What the research says
1 studyThis study found that when people swap sugary foods and drinks for ones with low-calorie sweeteners, they tend to lose a little weight—about 2.3 pounds—especially if they cut out a lot of sugar. But if they just drink diet soda without cutting sugar, they don’t lose weight. So, the sweeteners only help when they replace real sugar.
