Abstract

Aims

To test the efficacy of time-restricted eating (TRE) in comparison to dietitian-led individualised dietary guidance to improve HbA1c in people with Type 2 diabetes mellitus.

Methods

In a parallel groups design, 51 adults (35–65 y) with Type 2 diabetes mellitus and overweight/obesity (HbA1c ≥6.5% (48 mmol/mol), BMI ≥25-≤40 kg/m²) commenced a six-month intervention. Following baseline, participants were randomised to TRE (1000–1900 h) or DIET (individualised dietetic guidance) with four consultations over four months. Changes in HbA1c (primary), body composition, and self-reported adherence (secondary) were analysed using linear mixed models. A non-inferiority margin of 0.3% (4 mmol/mol) HbA1c was set a priori.

Results

Forty-three participants (56 ± 8 y, BMI: 33 ± 5 kg/m², HbA1c: 7.6 ± 0.8%) completed the intervention. HbA1c was reduced (P=0.002; TRE: −0.4% (−5 mmol/mol), DIET: −0.3% (−4 mmol/mol)) with no group or interaction effects; TRE was non-inferior to DIET (−0.11%, 95%CI: −0.50% to 0.28%). Body mass reduced in both groups (TRE: −1.7 kg; DIET: −1.2 kg) via ∼900 kJ/d spontaneous energy reduction (P<0.001). Self-reported adherence was higher in TRE versus DIET (P<0.001).

Conclusions

When individualised dietary guidance is not available, effective, and/or suitable, TRE may be an alternative dietary strategy to improve glycaemic control in people with Type 2 diabetes mellitus.

比较限时进食与标准饮食疗法对 2 型糖尿病患者血糖控制的影响：随机对照试验。

目的：测试限时进食（TRE）与营养师指导的个体化膳食相比对改善 2 型糖尿病患者 HbA1c 的效果：在平行分组设计中，51 名 2 型糖尿病和超重/肥胖（HbA1c ≥6.5% (48 mmol/mol)，体重指数≥25-≤40 kg/m2）的成人（35-65 岁）开始了为期 6 个月的干预。基线之后，参与者被随机分配到 TRE（1000-1900 小时）或 DIET（个性化饮食指导），在四个月内接受四次咨询。采用线性混合模型对 HbA1c（主要指标）、身体成分和自我报告的依从性（次要指标）的变化进行分析。先验设定的非劣效边际为 0.3%（4 毫摩尔/摩尔）HbA1c：43 名参与者（56 ± 8 岁，体重指数：33 ± 5 kg/m2，HbA1c：7.6 ± 0.8%）完成了干预。HbA1c 降低了（P=0.002；TRE：-0.4%（-5 mmol/mol），DIET：-0.3%（-4 mmol/mol））：-TRE 不劣于 DIET（-0.11%，95%CI：-0.50% 至 0.28%）。两组的体重都通过每天自发能量减少 900 千焦的方式有所下降（PConclusions.TRE：-1.7 千克；DIET：-1.2 千克）：当个体化饮食指导不可用、无效和/或不合适时，TRE 可能是改善 2 型糖尿病患者血糖控制的另一种饮食策略。
