Participants will be provided 50 or 100 grams of this food at all sessions depending on which condition they are randomized into. The chips provided to participants in each condition will be measured in grams to the tenth decimal point on an electronic food scale (Denver Instrument Co., Arvada, CO) before and after the session. The weight of the container will also be measured. Total grams of chips consumed during the session will be determined by subtracting pre- and post-consumption weight of the chips.
