Interestingly, it has been shown that non-obese patients with
COPD with more visceral fat mass compared to control subjects
were associated with increased IL-6 levels [38].
McDonald et al. concluded that, in obese COPD patients, dietary
energy restriction coupled with resistance strength training
results in clinically significant improvements in BMI, exercise
tolerance and health status, while preserving skeletal muscle
mass and importantly, this intervention resulted in an
improved prognostic score [39].
