Food For Thought
On the covers and elsewhere in her books, Rolls uses side-by-side photos of foods -- with the same number of calories -- that have high and low energy densities. So for instance, a sixth of a cheeseburger is shown alongside its caloric equivalent, a big, brimming bowl of soup. The implication is obvious. The soup will fill you up, while the burger fraction will leave you hungry for the remaining 5/6 -- and maybe a side of fries.
Of course, the photos and premise might not convince everyone. Some might believe that a spoonful of real chocolate mousse would be worth barrels of fresh fruit and yogurt parfait. Some might gladly take a small plate of potato chips and dip over a massive platter of raw vegetables with hummus and salsa.
But in a way, that's Rolls's point. If you'd prefer the spoonful of real mousse, or a few chips, she says go ahead and eat them. She doesn't forbid anything. However, her focus on energy density lets you see just how many calories there are in some of your favorite foods. Rolls teaches you how to better evaluate your choices. Knowing this might help you stop after a few bites of energy dense foods, rather than eating the whole serving like you used to.
All in all, the Volumetrics diet plan is a well-researched and sound approach to weight loss. It doesn't make any big promises and urges you to go slowly. Admittedly, following the meal plans -- which are all Volumetric recipes -- will require a fair amount of time in the kitchen. Some people may be turned off by having to calculate energy densities and keep daily records. But for people who dedicate themselves, Volumetrics could prove a sensible and satisfying way to lose weight.
