Abstract
The purpose of this investigation was to learn whether the thermogenic effect in man of sucrose and glucose were similar and whether normal weight and overweight subjects responded in a similar manner. Dietary-induced thermogenesis was calculated for the period 15 to 180 min after ingestion of sucrose or glucose in six normal weight and five obese subjects. The metabolic rate was calculated from the oxygen consumption and carbon dioxide output utilizing the ventilated hood technique. In normal weight subjects, the total dietary-induced thermogenesis was significantly greater after sucrose than after glucose (p < 0.005) but the difference was much less marked in the obese subjects.
