Brief Summary
Soybean peptides are a mixture of active peptides obtained from the hydrolysis of soybean protein, which have biological activities such as antioxidant, blood pressure lowering, anti-fatigue and lipid lowering, etc. They can regulate food intake, increase satiety, and reduce fat body ratio by reducing cholesterol and triglyceride content and stimulating CCK secretion.Conjugated linoleic acid (CLA) is a set of linoleic acid with conjugated unsaturated double bond, the location and structure of the isomers have been approved by the ministry of health in China as a new resource food , widely used in areas such as health care products, functional foods and food additives, animal experiments showed that it has reduce tumor, atherosclerosis, obesity risk.Therefore, in this study, the effect of conjugated linoleic acid combined with soybean peptide on overweight and obese people was investigated in a randomized controlled manner.

Outcome Measures
Primary Outcomes (5)
Liver fat content
Liver fat content will be measured by magnetic resonance (MR) which will be evaluated for change over the course of liver fat content. Baseline: Evaluate the initial fat content of the subjects; 24weeks: Evaluate whether the fat content of the subjects changes after the intervention.
Baseline & 24weeks
Fat and thin tissue
Body fat percentage will be screened with DXA apparatus.Assess the patient's physical condition. Baseline: Evaluate the body composition of the subjects to see whether they meet the inclusion criteria; 12 weeks: After 3 months of intervention, If the percentage of fat is lower than the baseline, the body composition is improved, if the proportion of fat increased by more than 5%, the test should be stopped in time. 24 weeks: Evaluate the improvement of body composition before and after the intervention. If the percentage of fat is lower than the baseline, the body composition is improved. Baseline: Evaluate the body composition of the subjects to see whether they meet the inclusion criteria; 12 weeks: After 3 months of intervention, the subjects will be evaluated for weight improvement.If the proportion of fat; 24 weeks: Evaluate the improvement of body composition before and after the intervention.
Baseline & 12 weeks & 24weeks
Adipocytokine
Adipocytokines will be detected by biochemical experiments to reveal the possible pathways of action of soybean peptides and conjugated linoleic acid. Baseline: Evaluate the levels of adipocytokines (such as leptin and adiponectin) before intervention; 24 weeks: Evaluate the levels of adipocytokines (such as leptin and adiponectin) after intervention, If the serum leptin and adiponectin levels change, it can provide a new idea for the combined weight loss mechanism of soybean peptide and conjugated linoleic acid.
Baseline & 24weeks
Inflammatory factor index
Inflammatory factor index will be detected by biochemical experiments to reveal the possible pathways of action of soybean peptides and conjugated linoleic acid. Baseline: Evaluate the levels of inflammatory factors (such CRP, IL-6) before intervention; 24weeks: Evaluate the levels of inflammatory factors after intervention, If the levels of inflammatory factors change, it suggests that soy peptides and conjugated acid oil may achieve weight loss through inflammatory pathway.
Baseline & 24weeks
Blood fat
Blood fat inde(such as TG, TC) will be detected by biochemical examination. Baseline: assess the physical condition of subjects to determine whether they meet the criteria for inclusion; 12 weeks: Evaluate the levels of TG, TC after three-months intervention, If there is a significant increase in Blood fat, the experiment should be stopped in time; 24 weeks: Evaluate the effect of lowering blood lipid of the subjects.
