Weight loss is known to be a potential side effect of methylphenidate, sold under the brand-name Ritalin. But whether the drug could help adults fight the battle of the bulge is still unknown, according to the study, published in the American Journal of Clinical Nutrition.
For the study, researchers had 14 adults take either a dose of Ritalin or a placebo just before offering them a buffet lunch.
Although the volunteers' pre-lunch hunger ratings were no different whether they took methylphenidate or the placebo, the Ritalin group ate less. On average, Ritalin takers downed 11 percent fewer calories and 17 percent less fat
