Science agrees with you: Once you eat one chip, you’re doomed to consume the whole bag.
Some foods (cookies, bread, candy) seem to ignite a fierce hunger to eat more, says Louis J. Aronne, director of the Comprehensive Weight Loss Program at New York Presbyterian Hospital/Weill Cornell Medical Center. His new book, The Skinny: On Losing Weight Without Being Hungry, argues that the conventional wisdom on weight loss—that calories are calories no matter what you eat—is wrong.
Certain foods, theorizes Dr. Aronne, promote what he calls “fullness resistance.” Refined carbohydrates and sugary and fatty foods interfere with the body’s “stop eating” signals, and you eat more. Eating vegetation, or foods high in protein, fiber, and water, seems to have the opposite effect.
This is not a totally new idea; weight watchers have probably already heard of the glycemic index of food, and of the Volumetrics diet plan. But it’s nice to hear an actual doctor confirm how hard it is to stop at one serving size for cookies.
