  1. Notes: Values are presented as mean ± S.D.
  2. *Comparison between hypocaloric diet group and metformin group p = 0.008;
  3. §Calculated with Harris and Benedict equation (ref.36 for men. Daily resting Energy Need = 88.362 + (13.398 × weight (kg)) + (4.799 × length (cm))− (5.677 × age).
  4. Total Energy Expenditure = Resting energy need × PAL.
  5. †According to formula of Hume (ref.37). Lean body mass = (0.32810 × weight (kg)) + (0.33929 × length (cm))−29.5336.
