Hypothesis
Does calcium supplementation affect body composition, weight loss, and insulin resistance in obese adults on a low-calorie diet?
Conclusion
Calcium supplementation did not significantly impact weight, body composition, insulin resistance, or blood pressure beyond what can be achieved through a calorie-restricted diet.
Supporting Evidence
- Calcium supplementation did not lead to significant changes in weight or body composition.
- Insulin concentration decreased significantly in the calcium group at the 12th week.
- Diastolic blood pressure decreased significantly in both groups at the 24th week.
Takeaway
This study found that taking calcium supplements while dieting didn't help people lose more weight or improve their health compared to just dieting alone.
Methodology

Limitations
The study did not measure skinfold thickness and had a relatively small sample size.
