The Study
Dietary fructose reduces circulating insulin and leptin, attenuates postprandial suppression of ghrelin, and increases triglycerides in women.
This study shows what happened to 12 women's hormones and fat levels in their blood after eating meals with fructose versus glucose on different days. It can tell us that fructose was linked to lower insulin and leptin, less ghrelin drop, and higher triglycerides — but it can't prove that eating fructose will make someone gain weight or get sick over time.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, these changes may make you feel hungrier and store more fat, even in healthy people.
- 2Fructose caused 65% less insulin, 33% less leptin, 30% less ghrelin drop, and higher triglycerides than glucose over 24 hours.
