"Obese and non-obese women respond to high-energy, high-density snacks in different ways," said Jennifer Temple, lead author of the study, which appears in the August issue of the American Journal of Clinical Nutrition.

Such information could one day be useful in tailoring dieting strategies for different people.

According to background information in the study, only 10 percent of people who lose weight through dieting and exercise manage to keep that weight off for five years.

Scientists have postulated that one reason for the high failure rate is that people feel deprived of their favorite foods and end up making up for their period of abstinence.
