Overweight or Obesity
Conditions
Brief summary
This study aimed to investigate the effects of the modified 5:2 IF dietary intervention on the Chinese population with overweight or obesity based on a self-controlled clinical trial.
Detailed description
There are fewer studies on the influence of dietary interventions on the Chinese populations with obesity, and the degree of obesity, body fat distribution, dietary pattern and structure, and metabolic status of populations with obesity are different between the Chinese and European populations. The effects of a 5:2 IF dietary intervention on the Chinese population with overweight or obesity are unclear. Therefore, this study aimed to investigate the effects of the modified 5:2 IF dietary intervention on the Chinese population with overweight or obesity based on a self-controlled clinical trial.
Interventions
DIETARY_SUPPLEMENTA modified 5:2 intermittent fasting diet
The modified 5:2 IF diet involves 2 nonconsecutive fasting days (25%-30% of the total required daily energy intake based on ideal body weight) and 5 days of habitual intake (limited total energy intake according to ideal body weight) per week, as well as a 4-week run-in period and a minimum of 6,000 steps of physical activity per day.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| body measurements | 24 weeks after intervention | weight, BMI, and waistline |
| glycolipid metabolism indicators | 24 weeks after intervention | fasting plasma glucose (FPG), fasting plasma insulin (FPI), fasting C-peptide (FCP), triglycerides (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and uric acid. |
| adipokines | 24 weeks after intervention | leptin and lipocalin |
| inflammatory factors before the modified 5:2 IF diet intervention and after 24 weeks of intervention | 24 weeks after intervention | high sensitivity C-reactive protein (hsCRP), interleukin 6 (IL-6), and tumor necrosis factor-alpha (TNF-α) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in metabolic components | 24 weeks after intervention | Participants' metabolic components were analyzed by serum metabolomics analysis. The ultra-high performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) (Agilent 1290, Agilent Technologies, Inc., USA) was applied to identify metabolites. |
