A new book by Barbara Rolls, professor of nutritional sciences and Helen A. Guthrie Chair in Nutrition at Penn State, aims to help people control their hunger while also losing weight. "The Ultimate Volumetrics Diet" will be available in stores and online on April 10. "There is no magic way to get around the fact that to lose weight you must reduce the calories you consume to below the number you burn," Rolls said. "However, cutting calories doesn't have to leave you feeling hungry. You can carefully choose the foods you eat so that you feel full and satisfied on fewer calories." (more)

Preschool children consumed nearly twice as many vegetables and 11 percent fewer calories over the course of a day when researchers from Penn State added pureed vegetables to the children's favorite foods.
"Childhood obesity rates are on the rise, and at the same time children are not eating the recommended amount of vegetables," said Barbara Rolls, professor of nutritional sciences and holder of the Helen A. Guthrie chair in nutritional sciences in Penn State's College of Health and Human Development. "Vegetables have been shown to help lower calorie intake. The problem is getting kids to eat enough vegetables." (more)

Increasing the amount of vegetables in the first course of preschool lunch could be a smart way to get children to eat more vegetables, according to Penn State nutrition researchers. "We have shown that you can use portion size strategically to encourage children and adults to eat more of the foods that are high in nutrients but low in calories," said Barbara J. Rolls, Helen A. Guthrie Chair of Nutritional Sciences. (more)

"There's no doubt that in the current environment it is very difficult to eat in reasonable amounts. You can use portion size to get people to eat more low-calorie foods. Calories really are the critical element of weight management... Using strategies to modify calorie density and portion size helps with weight control and weight loss."
-- Barbara Rolls, professor of nutrition and biobehavioral health and director of the Laboratory for the Study of Human Ingestive Behavior, speaking Monday (Nov. 16) on the subject of "Feeling Full on Fewer Calories," as part of the Penn State Forum. Rolls's clinically tested Volumetrics plan advocates eating more good low-calorie foods to increase satisfaction while reducing feeling hungry. She is the author of five books including "Thirst," "The Volumetrics Weight-Control Plan," "Feel Full on Fewer Calories" and "The Volumetrics Eating Plan."
