Researchers have new evidence that the widespread use of artificial sweeteners actually make it harder for people to control their intake and body weight.
Rats given yogurt sweetened with saccharin later consumed more calories, gained more weight, put on more body fat, and didn’t make up for it by cutting back later. The study’s authors surmised that the saccharin broke the connection between sweet sensations and high-calorie food, changing the body’s ability to regulate intake.
Problems with self-regulation might explain in part why obesity has risen in parallel with the use of artificial sweeteners.
