We observed any intervention-induced improvements in anthropometric and metabolic parameters in the control group of non-exercising PD patients (BMI, p = 0.81; body fat, p = 0.79; subcutaneous, p = 0.77 and visceral adiposity p = 0.81; muscle mass, p = 0.82; fasting glycemia, p = 0.74; 2-h glycemia, p = 0.74; fasting insulin, p = 0.37; HOMA-IR, p = 0.83; hsCRP, p = 0.38; total cholesterol, p = 0.77; HDL-cholesterol, p = 0.8535; TAG, p = 0.75). This evidence concerns the gene INS and Parkinson disease.
