AB  - OBJECTIVE: To examine the effects of consuming a galactose carbohydrate (CHO) 
      drink on substrate oxidation, postexercise satiety, and subsequent energy intake. 
      METHODS: Nine recreationally active eumenorrheic females undertook 3 trials, each 
      consisting of running for 60 minutes at 65% VO(2peak) followed immediately by a 
      90-minute rest period. Prior to (300 ml) and at 15-minute intervals during 
      exercise (150 ml), participants consumed either a glucose (GLU: GI 89) or 
      galactose (GAL: GI 20) drink, each of which contained 45 g of CHO, or an 
      artificially sweetened placebo (PLA). Following the rest period, participants 
      were provided with an ad libitum test lunch and asked to record food intake for 
      the remainder of the day. RESULTS: Plasma glucose was significantly greater 
      throughout exercise and rest following the GLU trial compared with the GAL and 
      PLA trials (P < 0.05); however there were no differences in CHO oxidation. Hunger 
      was significantly lower (P < 0.05) throughout the GAL compared to the GLU and PLA 
      trials. There were no significant differences between trials for energy intake 
      during the postexercise meal. Overall net energy balance for the 24 hours was 
      negative in both the GAL (-162 +/- 115 kcal; P < 0.05 vs GLU) and PLA trials (-49 +/- 
      160 kcal). CONCLUSIONS: Results demonstrate that ingesting a solution containing 
      GAL before and during exercise can positively impact postexercise satiety and 
      energy balance throughout the day, compared to a more readily available and 
      widely consumed form of CHO. Despite this, there appears to be no apparent 
      benefit in consuming a CHO beverage on fuel utilization for this moderate 
      exercise intensity and duration.
