[Obesity Discussion]

Acknowledgment: Our gratitude is extended to the excellent staffs of the Outpatient Clinic, Inpatient Clinic, Metabolic Kitchen, and Clinical Chemistry Laboratory. We also want to thank Claudia Van Skiver, LDN, RD (Ochsner Clinic, Baton Rouge, La) for developing the behavioral treatment manual and training the staff on how to use the HMR energy counting system. Our thanks also go to Health and Nutrition Technology, Carmel, Calif, for providing us with the HealthOne formula used in the study. Finally, our profound gratitude goes to all the volunteers who spent so much time participating in this very demanding research study.
