Abstract
Background: Time-restricted eating (TRE) shows promise for managing weight and metabolic issues, yet its application in real-world healthcare settings remains underexplored. This study aims to assess the real-world utilisation and short-term outcomes of TRE in clinical practice. Methods: This observational study used a retrospective chart review of 271 adults who attended a metabolic specialist clinic between 2019 and 2023. Descriptive statistics and multivariable logistic regression were used to identify factors associated with TRE adoption, while paired sample t-tests evaluated changes in outcomes among those who received TRE advice. Results: Among the 271 patients, 76% were female, 90% Caucasian, and 94% overweight/obese. Of all patients, 47.2% received TRE advice, mainly using the 16:8 method, alongside additional dietary guidance for 60% of patients. Working status and baseline metabolic profiles were the only factors significantly associated with TRE adoption. Among those who followed TRE, 81% experienced modest but significant reductions in weight (−1.2 kg, p < 0.01), BMI (−0.4 kg/m2, p < 0.01), and waist circumference (−3.7 cm, p < 0.01). Conclusions: This study highlights TRE as a feasible and practical dietary strategy for improving metabolic health in healthcare settings. However, further research and improved data capture are needed to explore long-term adherence, potential adverse effects, and the effectiveness of TRE across diverse patient populations.
