    At first, all participants were categorized according to age (<65 and ≥65 y) and pre-intervention BMI (25-29.9 and ≥30 kg/m2). Then, patients were randomly allocated into two groups to take either supplements or placebo. Randomization will be done by the use of computer-generated random numbers.
