Englert I, Bosy-Westphal A, Bischoff SC, et al. - Researchers investigated among overweight postmenopausal women, how changes in fat-free mass (FFM), resting energy expenditure (REE), and physical function (PF) during weight loss could be influenced by protein intake. Participants were 54 postmenopausal women (BMI 30.9 ± 3.4; age 59 ± 7 years); these were randomly allocated to 2 groups receiving energy-restricted diets with either 0.8 g (normal protein; NP) or 1.5 g protein/kg body weight (high protein; HP) for 12 weeks, followed by a 6-month follow-up phase with an ad libitum food consumption. At baseline, after weight loss, and after follow-up, experts recorded FFM, REE, and PF (strength, endurance, and balance). Findings revealed that preservation of FFM and REE remained unaffected by an HP weight-loss diet without exercise, however, this intervention may assist in maintaining muscle strength in postmenopausal women.
