Pros & Cons of Volumetrics
Volumetrics is a system of weight loss developed by nutritionist Barbara Rolls. Rolls is a professor of dietary science who has directed the Laboratory for the Study of Human Ingestive Behavior at Penn State University for many years. The volumetrics diet is based on her and her colleagues' extensive scientific research about human eating habits. Rolls has published her findings in many scientific papers as well as books designed for the layperson to follow easily. Her basic premise is that people should eat foods that will help them fill up and thus satiate their hunger for a longer period of time.

Nutritionally Sound
-
Rolls offers diet plans that are filled with vegetables, whole grains and fruit. Readers are given recipes filled with foods that will allow anyone who prepares them to eat a varied diet that meets your daily requirement of carbs, fats, vitamins and minerals. A dieter can follow her suggestions and be assured that they are eating nutritiously.
Go Slowly
-
Volumetrics stresses reasonable weight goals. Dieters are told they should aim for between a pound or 2 lbs. per week in weight loss. Rolls repeatedly points out that weight lost quickly is typically weight that will be regained quickly. She stresses slow weight loss that will allow the dieter to shed pounds long term and keep them off.
-
Varied Diet
-
The diet plan offered in Rolls' books places an emphasis on varied nutrition. No food is deemed forbidden. All foods are allowed, even chocolate and sweets. Rolls emphasizes eating sweet foods and fats in moderate amounts as well as foods that are high in fiber and water in order to fill up.
Calorie Density
-
Rolls points out that many people find it difficult to count calories. Instead she suggests that dieters focus on learning which foods are high in calorie density and which are low in caloric density. Instead of counting calories, a task that can be quite difficult, she suggests that dieters acquaint themselves with the general caloric values in many foods.
Hard to Prepare
-
The diet emphasized by Rolls places an emphasis on preparing items from scratch. Preparing food everyday can be quite difficult for someone who works full time. Searching for the right ingredients can be time consuming and costly.
Behavior
-
Not everyone eats because they're hungry. Many overweight people eat because they are bored, sad or frustrated. Rolls' techniques do not address the emotional aspects of eating at all.
