Eat more Protein; Stay Full Longer--Studies Say

Mar 07, 2016 09:40 AM EST | By Florence May P. Jose

Now, eating less carbs and loading up on protein makes more sense.

According to a new study published in the Journal of the Academy of Nutrition and Dietetics has found out that eating food with a higher protein content makes people feel fuller after each meal.

The authors of the study aimed to find out the relationship of protein consumption and an average person's notion of fullness. Considering previous studies made regarding the topic, they based their study on five stand outs and analyzed their methods.

Researchers found out that each of the five studies have close to similar results after experimentation, participants, who ate protein after fasting felt fuller for longer periods of time.

 "Our paper did show that indeed, higher protein intake led to greater sensations of fullness," says study co-author Richard Mattes, distinguished professor of nutrition science at Purdue University told Time

But how does the body feel full by just consuming protein? According to co-author Heather Leidy, an assistant professor of nutrition at the University of Missouri, the mystery is still "not resolved".

Health reports that nutrition researcher Richard Mattes of Purdue University has analyzed the newest study.

"A good deal of evidence suggests that protein activates satiety [fullness] hormone release and so should be most strongly tied with fullness ratings," Mattes, director of Purdue's Ingestive Behavior Research Center, said in a journal news release.

"Feelings like hunger and fullness are not the only factors that influence [calorie] intake," Mattes said. "We often eat for other reasons. Anyone who has ever felt too full to finish their meal but has room for dessert knows this all too well."

Other nutrition experts acknowledge the helpfulness of the most recent study conducted, but the effectiveness of the diet approach has still lapses, especially in long term effectiveness.

"While this information may be useful to spur additional studies on this topic and how it relates to calorie intake and weight, we cannot conclude that more protein means more weight loss," said Erin Keane, a nutritionist at Lenox Hill Hospital, in New York City.

"The studies [examined in the new review] differed greatly in the amount of protein eaten, as well as the amount of overall calories eaten at a given sitting," she noted. "Also, the studies did not provide insight into whether or not increased fullness actually led to decreased overall intake in a given day.
