Liquid versus solid carbohydrate: effects on food intake and body weight
BACKGROUND : Beverages are contributing an increased proportion of energy to the diet . Because they elicit a weak compensatory dietary response , they may increase risk of positive energy balance . OBJECTIVES : This study aim ed to document the differential effects of matched liquid and solid carbohydrate loads on diet and body weight . DESIGN : In a cross-over design , seven males and eight females consumed dietary carbohydrate loads of 1880 kJ/day as a liquid ( soda ) or solid ( jelly beans ) during two 4 week periods separated by a 4 week washout . Subjects were permitted to consume the loads however they chose . In addition to baseline measurements , diet records were obtained on r and om days throughout the study , body composition was measured weekly , physical activity was assessed before and after treatments and hunger was assessed during washout and midway through each treatment . RESULTS : Free-feeding energy intake during the solid period was significantly lower than intake prior to this period . Dietary energy compensation was precise ( 118 % ) . No decrease in free-feeding energy intake occurred during the liquid period . Total daily energy intake increased by an amount equal to the load result ing in dietary compensation of −17 % . Consequently , body weight and BMI increased significantly only during the liquid period . Physical activity and hunger were unchanged . CONCLUSIONS : This study indicates that liquid carbohydrate promotes positive energy balance , whereas a comparable solid carbohydrate elicits precise dietary compensation . Increased consumption of energy-yielding fluids may promote positive energy balance
