The Claim
In physically active young adults, males exhibit significantly higher fat oxidation rates during a 2-hour treadmill walk in 40°C heat compared to females, with a mean difference of 0.34 g/min at 30 minutes of exercise, despite no differences in subcutaneous abdominal adipose tissue lipolysis or systemic biomarkers of fat metabolism, suggesting sex-based differences in whole-body fuel utilization may arise from factors beyond adipose tissue breakdown.
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.
During a 2-hour walk in 40°C heat, physically active young men burn fat at a higher rate than young women, with a measurable difference of 0.34 grams per minute at the 30-minute mark, even though both groups show similar levels of fat breakdown in abdominal tissue and similar blood markers of fat metabolism.

What the research says
1 studyIn hot weather, men burned more fat than women during a 2-hour walk on a treadmill, even though their bodies broke down fat from belly fat the same way. This suggests men and women use energy differently, even when their fat stores behave the same.
