| dc.description.abstract | This study was conducted to test the hypothesis that 1% chocolate milk will increase mealtime satiation and decrease short-term food intake (FI) to a greater extent than other isovolumetric sugars-sweetened beverages in normal weight (NW) and overweight/obese (OW/OB) boys, although the effect will be diminished in OW/OB boys. The primary objective was to determine the effect of isovolumetric (350 ml) preloads of fruit drink, cola and 1% chocolate milk on short-term FI and subjective appetite when compared to a water control in 9-14 year old NW and OW/OB boys. On four separate mornings and in random order, boys consumed a calorie-free water control, fruit drink (154 kcal), cola (158 kcal) or 1% chocolate milk (224 kcal) beverage 2 hours after a standardized breakfast. Boys significantly reduced FI after cola (NW: 894 ± 54; OW/OB: 986 ± 75) and 1% chocolate milk (NW: 844 ± 52; OW/OB: 912 ± 63) compared to a water control (NW: 1046 ± 51; OW/OB: 1050 ± 49). Caloric compensation (CC) scores were not significantly different between groups for the fruit drink (NW: 44% vs. OW/OB: 16%, p=0.56), cola (NW: 96% vs. OW/OB: 40%, p=0.27) or 1% chocolate milk (NW: 90% vs. OW/OB: 61%, p=0.24) treatments. When corrected for the energy content of the treatment, fullness was higher after cola (p=0.02), and prospective food consumption (PFC) lower after 1% chocolate milk (p=0.009) compared to the fruit drink. PFC and DTE were the strongest and weakest predictors of FI, respectively. BW was positively associated with FI and inversely associated with CC in OW/OB, but not NW boys (P<0.05). In OW/OB, the treatment dose of cola (kcal/kg BW) was inversely associated with FI (P<0.05). In conclusion, cola and 1% chocolate milk suppressed FI in boys, however, the effect on FI was dependent on macronutrient composition, treatment dose and body composition. | en_US |
