Strong Support
After eating meals containing only sugars like glucose and fructose—without any fat—healthy adult men experience a sustained drop in free fatty acids in their blood for up to six hours, primarily due to insulin reducing fat breakdown rather than sugars being converted into fat.

Characteristics and correlation analysis of postprandial free fatty acids and cortisol levels in males after different meals: a clinical trial
Randomized Controlled Trial
Human
2026After eating sugar (glucose or fructose), the body releases insulin, which tells fat cells to stop releasing fatty acids into the blood — and that’s exactly what happened in this study. Even though no fat was eaten, fatty acid levels stayed low for 6 hours, showing insulin is in charge.
