Summary

Night-eating syndrome, characterized by morning anorexia, evening hyperphagia, and insomnia, affects 26% of the severely obese in the US. Leptin, a hormone from adipocytes, is linked to this syndrome and night eating behaviors.

Area of Science:

  • Behavioral Science
  • Endocrinology
  • Obesity Research

Context:

  • Night-eating syndrome (NES) is characterized by morning anorexia, evening hyperphagia, and insomnia.
  • First described in 1955, NES is associated with stress and poor weight reduction outcomes.
  • Prevalence is approximately 26% in the severely obese US population, with limited studies in Japan.

Purpose:

  • To explore the behavioral patterns and neuroendocrine factors associated with night-eating syndrome.
  • To investigate the relationship between leptin, adiposity, and night eating behavior.

Summary:

  • NES presents a coherent behavioral pattern in affected individuals.
  • Neuroendocrine studies suggest a link between leptin, produced by adipocytes, and NES.
  • The syndrome's prevalence may increase with rising adiposity.

Impact:

  • Highlights the potential role of leptin in night eating behaviors.
  • Underscores the need for further research into NES, particularly in non-US populations.
  • Informs potential therapeutic targets for obesity and eating disorders.
