Acute Effects of Fats on Satiety and Energy Needs

Not Applicable

Completed

• Conditions: Obesity

• Registration Number: NCT02496936
• Lead Sponsor: USDA Grand Forks Human Nutrition Research Center

Brief Summary

The purpose of this study is to assess the acute effect of dietary fat on satiety and energy metabolism.

Detailed Description

The influences of specific dietary fat sources on satiety, appetite and energy utilization remains unclear; evidence is lacking on whether responses vary according to acute intake. The researchers will use a controlled setting to determine whether the source of dietary fat is related to perceived satiety, satiety hormone responses, and energy expenditure by conducting experiments to evaluate short term (acute) effects.
