Slower Eating Reduces Hunger but Not Necessarily Intake

Significantly cuts caloric intake in the normal-weight, but not in the overweight/obese

MONDAY, Jan. 6, 2014 (HealthDay News) -- While slower eating speed reduces hunger, it does not significantly lower caloric intake in overweight/obese individuals, according to research published online Jan. 2 in the Journal of the Academy of Nutrition and Dietetics.

Meena Shah, Ph.D., of the Texas Christian University in Fort Worth, and colleagues monitored consumption for men and women (35 normal-weight; 35 overweight/obese) at lunch for two days to assess the effect of eating speed on energy intake.

The researchers found that energy intake at the meals was significantly lower for the slow versus the fast eating speed for the normal-weight individuals (804.5 ± 438.9 kcal versus 892.6 ± 330.2 kcal; P = 0.04) but not for the overweight/obese individuals (667.3 ± 304.1 kcal versus 724.8 ± 355.5 kcal; P = 0.18). Both groups reported significantly less hunger and had significantly lower meal energy density and eating rates during slow versus fast eating conditions. Normal-weight individuals, but not overweight/obese individuals, had significantly more fullness at 60 minutes from the start of the meal during slow versus fast eating speeds.

"Consuming a meal at a slower versus faster speed resulted in a significant reduction in food and energy intake in normal-weight but not in overweight/obese subjects," the authors write.
