Increased 24-hour ad libitum food intake is associated with lower plasma irisin concentrations the following morning in adult humans.

ABSTRACT:

Background

The relationship between food intake and irisin concentrations in humans is unclear.

Objectives

To determine whether the previous day's intake impacts fasting plasma irisin concentrations, or whether fasting irisin concentrations associate with subsequent ad libitum food intake.

Methods

Sixty-six nondiabetic adults (42 men) were admitted for a study of the determinants of energy intake. After 6 days of a weight maintaining diet, ad libitum energy intake over 3 days was assessed using a vending machine paradigm. Fasting plasma irisin concentrations were measured on the morning of the second day of the vending period.

Results

There were no correlations between irisin and demographic or anthropometric parameters. On day 1, subjects consumed 144 ± 52% of
