The Impact of the Physiological Response to Sugar on Brain Activity and Behavior

Participants will consume flavored beverage solutions containing 110 calories of sucrose in 6 exposure sessions within 1 week. One exposure session will include pre- and post-consumption blood draws and indirect calorimetry measurements inside a metabolic chamber over a 2-hour period. The other 5 exposure sessions will occur at specified times outside the laboratory sessions. Subjective ratings of internal state (i.e., hunger, fullness, and thirst) will be collected throughout each exposure. Subjective ratings of liking and wanting of each beverage will also be assessed.

Participants will consume flavored beverage solutions containing 110 calories of glucose in 6 exposure sessions within 1 week. One exposure session will include pre- and post-consumption blood draws and indirect calorimetry measurements inside a metabolic chamber over a 2-hour period. The other 5 exposure sessions will occur at specified times outside the laboratory sessions. Subjective ratings of internal state (i.e., hunger, fullness, and thirst) will be collected throughout each exposure. Subjective ratings of liking and wanting of each beverage will also be assessed.

Participants will consume flavored beverage solutions containing 110 calories of fructose in 6 exposure sessions within 1 week. One exposure session will include pre- and post-consumption blood draws and indirect calorimetry measurements inside a metabolic chamber over a 2-hour period. The other 5 exposure sessions will occur at specified times outside the laboratory sessions. Subjective ratings of internal state (i.e., hunger, fullness, and thirst) will be collected throughout each exposure. Subjective ratings of liking and wanting of each beverage will also be assessed.
