article imageStudy: Aspartame, saccharin cause greater weight gain than sugar

A new study shows that saccharin and aspartame cause a greater weight gain than sugar, even with the same intake of calories.
The study was led by Fernanda de Matos Feijóa of the Faculty of Medicine of the Federal University do Rio Grande do Sul, Ramiro Barcelos in Porto Alegre, Brazil.
Researchers gave rats plain yogurt sweetened with aspartame, saccharin, or sugar, plus their regular diet, for twelve weeks. Rats that ate the aspartame or saccharin sweetened yogurt gained more weight than those on the sugar sweetened yogurt, despite all the groups ingesting a similar amount of calories. Researchers think that the artificial sweeteners caused a decrease in energy used, or caused fluid retention. The study was published in the journal Appetite.
Previous research on humans shows that aspartame increases appetite and that many artificial sweeteners increase the motivation to eat. Sweet tastes from artificial sweeteners without calories could lead to greater ingestion of calories.
Thus artificial sweeteners contribute to obesity instead of preventing it.
