The Claim

In trained adult males, the rate of lipid oxidation measured 60 minutes after exercise is strongly correlated with the rate of carbohydrate oxidation during the prior high-intensity exercise session (r = 0.80–0.86), suggesting that higher carbohydrate utilization during exercise predicts greater fat oxidation during post-exercise recovery.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If a fit guy burns more carbs during a tough workout, he's likely to burn more fat afterward while recovering.

See the scientific wording

In trained adult males, the rate of lipid oxidation 60 minutes after exercise strongly correlates with the rate of carbohydrate oxidation during the preceding exercise session (r = 0.80–0.86), indicating that greater carbohydrate utilization during high-intensity effort predicts higher fat burning during recovery.

  1. Study: Isocaloric High-Intensity Interval and Circuit Training Increases Excess Post-Exercise Oxygen Consumption and Lipid Oxidation Compared to Moderate-Intensity Continuous Training

    The study found that when men burned more carbs during intense workouts, they also burned more fat afterward, which supports the idea that using more carbs during exercise leads to higher fat burning during recovery.
