Intermittent power restriction, time-restricted consuming and steady power restriction can all enhance blood sugar ranges and physique weight in folks with weight problems and sort 2 diabetes, in line with a research introduced at ENDO 2025, the Endocrine Society’s annual assembly in San Francisco, California.
“This research is the primary to check the results of three completely different dietary interventions intermittent power restriction (IER), time-restricted consuming (TRE) and steady power restriction (CER) in managing kind 2 diabetes with weight problems,” mentioned Haohao Zhang, Ph.D., chief doctor at The First Affiliated Hospital of Zhengzhou College in Zhengzhou, China.
Though researchers recognized improved HbA1c ranges, and opposed occasions have been comparable throughout the three teams, the IER group confirmed larger benefits in decreasing fasting blood glucose, bettering insulin sensitivity, decreasing triglycerides, and strengthening adherence to the dietary interventions.
“The analysis fills a niche in immediately evaluating 5:2 intermittent power restriction with a 10-hour time-restricted consuming in sufferers with weight problems and sort 2 diabetes. The findings present scientific proof for clinicians to decide on applicable dietary methods when treating such sufferers,” Zhang mentioned.
Zhang and colleagues carried out a single-center, randomized, parallel-controlled trial on the First Affiliated Hospital of Zhengzhou College from November 19, 2021 to November 7, 2024.
Ninety sufferers have been randomly assigned in a 1:1:1 ratio to the IER, TRE or CER group, with constant weekly caloric consumption throughout all teams. A workforce of nutritionists supervised the 16-week intervention.
Of these enrolled, 63 accomplished the research. There have been 18 females and 45 males, with a mean age of 36.8 years, a imply diabetes period of 1.5 years, a baseline BMI of 31.7 kg/m², and an HbA1c of seven.42%.
On the finish of the research, there have been no vital variations in HbA1c discount and weight reduction between the IER, TRE and CER teams. Nonetheless, absolutely the lower in HbA1c and physique weight was biggest within the IER group.
In comparison with TRE and CER, IER considerably diminished fasting blood glucose and triglycerides and elevated the Matsuda index, a measure of whole-body insulin sensitivity. Uric acid and liver enzyme ranges exhibited no statistically vital adjustments from baseline in any research group.
Two sufferers within the IER group and the TRE group, and three sufferers within the CER group, skilled delicate hypoglycemia.
The IER group had the very best adherence charge (85%), adopted by the CER group at 84% and the TRE group at 78%. Each the IER and CER teams confirmed statistically vital variations in contrast with the TRE group.
Zhang mentioned these findings spotlight the feasibility and effectiveness of dietary interventions for individuals who have weight problems and sort 2 diabetes.
