The purpose of this study is to estimate the effects of diet and exercise interventions on body weight, cardiovascular metabolic markers, executive function, and intestinal flora among undergraduate students, as well as the underlying mechanisms.
In recent decades, unhealthy dietary patterns and insufficiency of physical activity have brought negative effects on human health, such as rapid increasing incidence of obesity, metabolic cardiovascular diseases, and mental disorders. The first line of prevention and therapy for these diseases is proper diet and lifestyle interventions. A series of studies conducted in vivo and vitro have shown that high-fiber diets and time-restricted eating present benefits in weight loss, reducing cardiovascular disease risk, and improving cognitive function. While, there is also a randomized controlled trial do not observe the effects of time-restricted eating on weight loss and decrease of metabolic risks. Meanwhile, few studies have examined the effects of high-fiber diets or time-restricted eating on executive function. Additionally, previous studies on high-fiber diets and time-restricted eating focused on middle-aged or elderly populations with some features of metabolic syndrome, while the effects on healthy young populations are unclear. More importantly, there are a small amount of studies exploring the combined effects of time-restricted eating and physical activity on metabolism and cognitive function. Therefore, our study is to estimate the effects of diet (high-fiber diets and time-restricted eating) and exercise (rope-skipping) interventions on body weight, cardiovascular metabolic markers, executive function, and intestinal flora among undergraduate students, as well as the underlying mechanisms.

| Diet | Behavioral | Diet interventions include ten-hour time-restricted eating and a high-fiber diet.
|
|
| Baseline (1-2 days before the intervention), right after intervention (12 weeks) |
| Systolic and diastolic blood pressure | Sitting systolic and diastolic blood pressure were measured with a validated electronic blood pressure monitor (model OMRON,HEM-7124). | Baseline (1-2 days before the intervention), right after intervention (12 weeks) |
| Serum lipid levels | Serum lipid levels (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides) were analyzed by the enzymatic method. | Baseline (1-2 days before the intervention), right after intervention (12 weeks) |
| Fasting plasma glucose | Fasting plasma glucose were analyzed by the glucose oxidase method. | Baseline (1-2 days before the intervention), right after intervention (12 weeks) |
