About

To compare the effects of ingesting 100, 50 and 10 calories of glucose as compared to a non-calorie placebo (0 calorie beverage) on self-control over resisting snack foods. To test whether there is a threshold of glucose that will result in improved ease of resistance to problem foods (tested by comparing three different levels of glucose).

Full description

Ingestion of 100 calories of glucose during individually pre-determined times of waning dietary self-control will result in improved ease of resistance to problem foods when compared to ingestion of lower calories of glucose or placebo (0 calorie beverage)
