Intermittent vitality restriction, time-restricted consuming and steady vitality restriction can all enhance blood sugar ranges and physique weight in folks with weight problems and sort 2 diabetes, in line with a research being offered Sunday at ENDO 2025, the Endocrine Society’s annual assembly in San Francisco, Calif.
“This study is the first to compare the effects of three different dietary interventions intermittent energy restriction (IER), time-restricted eating (TRE) and continuous energy restriction (CER) in managing type 2 diabetes with obesity,” stated Haohao Zhang, Ph.D., chief doctor at The First Affiliated Hospital of Zhengzhou College in Zhengzhou, China.
Though researchers recognized improved HbA1c ranges, and antagonistic occasions had been comparable throughout the three teams, the IER group confirmed higher benefits in lowering fasting blood glucose, bettering insulin sensitivity, decreasing triglycerides, and strengthening adherence to the dietary interventions.
“The research fills a gap in directly comparing 5:2 intermittent energy restriction with a 10-hour time-restricted eating in patients with obesity and type 2 diabetes. The findings provide scientific evidence for clinicians to choose appropriate dietary strategies when treating such patients,” Zhang stated.
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 had 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 median 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. Nevertheless, absolutely the lower in HbA1c and physique weight was best within the IER group.
In comparison with TRE and CER, IER considerably lowered 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 modifications 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 best adherence fee (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 stated these findings spotlight the feasibility and effectiveness of dietary interventions for individuals who have weight problems and sort 2 diabetes.
The research is titled, “Intermittent versus Time-Restricted or Continuous Calorie Restriction for the Management of Obesity with Type 2 Diabetes: A Randomized Clinical Trial,” and it will likely be offered on Sunday, July 13.
