The Claim

During exercise under fasting conditions, the antilipolytic effect mediated by alpha-2-adrenergic receptors is more pronounced in obese men compared to lean men, indicating greater suppression of fat breakdown in obesity at baseline.

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.

How it works
1 study reviewed
In plain English

In fasted individuals exercising, fat breakdown is more strongly suppressed in obese men than in lean men due to the activity of alpha-2-adrenergic receptors.

    When fasting and exercising, obese men’s bodies are better at shutting down fat breakdown than lean men’s — and this study proves it. Eating a fatty meal before exercise removes this difference.
