(TRE) significantly decreased body weight by more than 2 kg in young adults with overweight or obesity.
TRE alone or with (RT) reduced body mass index (BMI) by approximately 1 kg/m.
decreased by 3.2 ± 0.4 kg when TRE was combined with RT, compared to 1.1 ± 0.5 kg with RT alone.
Fat-free mass decreased by 2.3 ± 0.6 kg with TRE, while RT increased fat-free mass by 1.6 ± 0.3 kg.
Both TRE and TRE+RT interventions led to similar reductions in waist and hip circumferences.
RT significantly lowered diastolic blood pressure by -5.5 ± 1.9 mmHg, while TRE+RT reduced it by -4.1 ± 1.5 mmHg.
Mild anxiety levels normalized post-intervention in the TRE+RT group but not in the RT group.

BACKGROUND/OBJECTIVE: Dietary restriction or exercise regimens can promote weight loss or physical fitness among patients with obesity. However, intervention-associated adverse effects may impede patients' motivation to participate in dietary/exercise interventions. We examined the effects of (TRE) with or without (RT) on body composition, mood profile, and sleep quality in young college adults with overweight or obesity.
METHODS: Fifty-four young college students with overweight/obesity were randomized into control (CON), TRE, RT, and TRE plus RT (TRE+RT) trials. The TRE trials restricted to an eating window of 10-hour/day for 8-week. The RT trials performed supervised resistance exercise, while the control trial maintained a regular lifestyle. Changes in body composition variables, blood pressure, mood status, and sleep quality were measured before and after the intervention.
RESULTS: TRE intervention alone or in combination with RT significantly ( < 0.01) decreased body weight (>2 kg) and BMI (~1 kg/m) in adults with overweight/obesity. Both RT alone and combined with TRE substantially decreased by 1.1 ± 0.5 and 3.2 ± 0.4 kg, respectively. The decreased fat mass was greater in the combination trial than in the RT trial, whereas TRE alone had no effect. In contrast, fat-free mass was significantly ( < 0.01) decreased with TRE (-2.3 ± 06 kg), increased with RT (1.6 ± 0.3 kg), and was stably maintained with combination interventions. The reduced waist and hip circumferences in the TRE ( < 0.01) were similar to those in the TRE+RT trials, however, RT alone had no effect. Time and group interaction showed a large effect size (partial eta squared) for all body composition variables. In addition, RT with or without TRE notably decreased diastolic blood pressure (RT: -5.5 ± 1.9 mmHg, TRE+RT: -4.1 ± 1.5 mmHg, < 0.05). Mild anxiety levels at baseline in RT (4.8 ± 2.6) and TRE+RT (4.1 ± 3) trials were found to be normal at postintervention in TRE+RT (3.6 ± 1.7) but not in RT (5.6 ± 3.5). No depression or stress was recorded among the participants during the intervention. The reported poor sleep quality among participants at baseline was significantly improved with RT (4.8 ± 2.9; < 0.05), and tended to improve with TRE+RT interventions (4.5 ± 1.9). p p p p p2
CONCLUSIONS: 10-hour TRE is beneficial for weight/fat loss without affecting mood status. However, TRE combined with RT might be more effective for weight/fat loss, maintaining muscle mass, and good quality of sleep among young adults with overweight or obesity.
