Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Understanding the effects of energy content, food form, and learning on satiation, satiety, and energy intake will allow for a greater understanding of the mechanisms of energy imbalance as a whole. Food choice is dictated by sensory properties and post-ingestive effects. By utilizing foods with similar sensory properties, the acquired knowledge derived from ingesting these foods can be monitored by analyzing subsequent intake at the same meal and at subsequent eating occurrences. It is hypothesized that the liquid food form will elicit weaker dietary compensation; that is, energy intake at other eating events will not be adjusted to compensate for that food. In addition, it is posited that the lower energy food will cause lower compensation postprandially. By having participants consume the same test food daily over a two week learning period, it is thought that they will show improved dietary compensation when the initial testing is repeated due to learned associations between food properties and metabolism.
