Thirty healthy overweight and obese female subjects (41.9 ± 12 years, 166 cm ± 7 cm, a 100.5 kg ± 19.6 kg, 46.0% ± 4.0% body fat, and BMI 37.4 ± 6.9) participated in the study. A 14-day dietary intervention examined acute effects of energy balance and macronutrient type on dietary intake, REE, body weight, body composition, and thyroid panel. Significant changes occurred in weight loss over time (p < 0.001); body fat mass over time (p < 0.001) and time x diet (p = 0.02); body fat percentage over time (p < 0.002) and time x diet (p = 0.023); REE over time (p = 0.03), and thyroid panel. Body weight continued to decrease during positive energy balance, yet metabolism rebounded. Results suggest energy balance has a greater overall effect on REE and weight loss than macronutrient type.vii, 84 p. : ill.1283981 bytes772950 bytesapplication/pdfapplication/pdfen-USBaylor University theses are protected by copyright.
