A Randomized, Open-label, Parallel Groups-controlled Clinical Trial to Evaluate the Effect of Calcium Plus Vitamin D Supplementation on Weight Management in Overweight and Obese Very-low Calcium Consumers

• Status: Completed
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 53 (actual)
• Sponsor: Changhai Hospital · Academic / Other
• Sex: All
• Age: 18 Years – 25 Years
• Healthy volunteers: Accepted

Summary

The purpose of the study is to determine whether calcium plus vitamin D supplementation is conducive to weight and fat loss during energy restriction in very-low calcium consumers.

Detailed description

Due to the contradicting findings in the hypothesis of calcium supplementation on weight and fat loss, which might be explained by the difference in initial calcium intake, the present study is aimed to evaluate the effect of calcium plus vitamin D supplementation on accelerating weight and fat loss in overweight or obese subjects with very-low calcium consumption(\<600mg/day). The hypotheses to be tested are: Calcium plus vitamin D supplementation is conducive to body weight and fat loss in overweight or obese young adults during energy restriction 12 weeks after randomization.

Conditions

• Obesity
• Overweight
