Study Summary
One reason people gain weight is eating more calories from food than what they need for energy over 24 hours. Metabolism is the amount of energy a person uses over 24 hours. Researchers want to study the relationship between changes in metabolism and how much a person eats. Objectives: To see how much food a person eats when the body's temperature is cooled. To study how changes in metabolism may alter the amount of food a person eats. Eligibility: Healthy people ages 18-55. Design: Participants will stay at NIH for 20 days. During the first 4 days, participants will have: * Medical exam * Electrocardiogram * Blood and urine tests. One blood test includes drinking a sugar solution. * DXA body composition scan * Questions about foods they like, physical activity, and personal behavior * Exercise test on a stationary bicycle Participants will spend 24-hour periods in a metabolic chamber. The chamber will be at normal room temperature or cooler. Some times, participants will eat a diet that matches their daily needs (fixed or eucaloric). Other times, they can eat as much as they wish from a vending machine (ad libitum). Participants will have blood and urine collected. Participants will swallow an ingestible wireless sensor and wear a small data recorder device. On the second to last day, participants will stay in the metabolic chamber but only consume water and non-caffeinated sugar-free beverages. Participants will come back for 1-day visits at six months and one year from the first admission. They will have blood and urine tests, and a DXA scan. They will answer questions on physical activity and food habits.
