America's Top 10 Healthiest Diets
An estimated 80 million Americans go on diets every year, spending more than $30 billion annually on programs and products. That’s a lot of money, a lot of advice, and a lot of emotional investment.
The Volumetrics Eating Plan
Nutritionist Barbara Rolls, PhD, has tapped into a fundamental human quality: We like to feel full. This may sound obvious, but it’s based, in fact, on extensive work Rolls has done as director of the Laboratory for the Study of Human Ingestive Behavior at Pennsylvania State University. Rolls says you’ll eat better and lose weight if you focus on the energy density of foods. And her Volumetrics plan explains how low-density foods like fruits and vegetables, as well as soups and stews, fill you up without overloading you with calories.
This diet scored highest for its safe weight-loss-rate and nutritional components because it’s “based on sound nutrition principles and overall healthy food choices,” judge Samantha Heller says. And our panelists found the plan’s 150-plus recipes appealing. Another plus, judge Christine Palumbo says, is Volumetric’s creative approach of showing photos of low- and high-density foods side by sidea simple way to help dieters visualize good choices.
Though exercise plays a secondary role in the Volumetrics plan, it is required. And a guide for logging 30 to 60 minutes of daily activity provides motivation. But Health’s Frances Largeman-Roth wondered if some dieters would need more exercise challenges and support.
