Effect of intermittent fasting 16:8 and 14:10 compared with control‐group on weight reduction and metabolic outcomes in obesity with type 2 diabetes patients: A randomized controlled trial.

Aims/Introduction: To compare the percent weight change and metabolic outcomes among diabetic participants with obesity on intermittent fasting (IF) 16:8, IF 14:10, or normal controlled diets. Materials and Methods: A randomized controlled trial was conducted to randomize participants into three groups. Each group followed IF 16:8, IF 14:10, according to the protocol 3 days/week for 3 months or a control group. Results: A total of 99 participants completed the study. The percentage weight change from baseline was −4.02% (95% CI, −4.40 to −3.64) in IF 16:8, −3.15% (95% CI, −3.41 to −2.89) in IF 14:10, and −0.55% (95% CI, −1.05 to −0.05) in the control group. The percentage weight loss from baseline was significantly more in both IF groups (P < 0.001, both) when compared with the control group. Weight loss was significantly more in the IF 16:8 group than in that of the IF 14:10 group (P < 0.001). Metabolic outcomes (decrease in FBS and HbA1C, and improvement in lipid profiles) were significantly improved from baseline in both IF groups in comparison with the control group. Conclusions: Either IF 16:8 or 14:10 had a benefit in the percentage weight change, glucose and lipid profiles in obese diabetic patients compared with the control group when consumed for 3 days a week for 3 months.
