This study examined nearly 78,700 women aged 50 to 69 for one year. Artificial sweetener usage increased with relative weight, and users were significantly more likely to gain weight compared to those who did not use artificial sweeteners, regardless of their initial weight.
According to the researchers, the results “were not explicable by differences in food consumption patterns. The data do not support the hypothesis that long-term artificial sweetener use either helps weight loss or prevents weight gain.”
