The Claim

Consumption of a high-fat meal increases plasma nonesterified fatty acid levels during exercise in both lean and obese men, without altering systemic epinephrine or norepinephrine concentrations.

Source: Acute exposure to long-chain fatty acids impairs α2-adrenergic receptor-mediated antilipolysis in human adipose tissue Published, JLR Papers in Press, July 11, 2007.

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.

Cause and effect
1 study reviewed
In plain English

Eating a high-fat meal before exercising raises levels of free fatty acids in the blood of both lean and obese men, but does not change the levels of the stress hormones epinephrine and norepinephrine in the bloodstream.

See the scientific wording

A high-fat meal increases plasma nonesterified fatty acid levels in both lean and obese men during exercise, but does not alter systemic hormonal responses such as epinephrine or norepinephrine.

What the research says

1 study

  1. Study: Acute exposure to long-chain fatty acids impairs α2-adrenergic receptor-mediated antilipolysis in human adipose tissue Published, JLR Papers in Press, July 11, 2007.

    Eating a fatty meal before exercising raises fat levels in the blood in both lean and obese men, but doesn’t change the stress hormones like adrenaline — just like the claim says.
