Journal ArticleDOI
Short sleep duration increases energy intakes but does not change energy expenditure in normal-weight individuals
Marie-Pierre St-Onge,Amy L. Roberts,Jinya Chen,Michael Kelleman,Majella O'Keeffe,Arindam RoyChoudhury,Peter B. Jones +6 more
TL;DR: The data show that a reduction in sleep increases energy and fat intakes, which may explain the associations observed between sleep and obesity.
Journal ArticleDOI
Short sleep duration, glucose dysregulation and hormonal regulation of appetite in men and women.
Marie-Pierre St-Onge,Marie-Pierre St-Onge,Majella O'Keeffe,Amy L. Roberts,Arindam RoyChoudhury,Blandine Laferrère,Blandine Laferrère +6 more
TL;DR: The data suggest that, in the context of negative energy balance, short sleep does not lead to a state of increased insulin resistance, but may predispose to overeating via separate mechanisms in men and women.
Journal ArticleDOI
Low Circulating Adropin Concentrations with Obesity and Aging Correlate with Risk Factors for Metabolic Disease and Increase after Gastric Bypass Surgery in Humans
Andrew A. Butler,Charmaine S. Tam,Kimber L. Stanhope,Bruce M. Wolfe,Mohamed R. Ali,Majella O'Keeffe,Marie-Pierre St-Onge,Eric Ravussin,Peter J. Havel +8 more
TL;DR: Although males exhibit higher adropin levels that are reduced by obesity, aging and markers of insulin resistance are associated with low plasmaAdropin irrespective of sex.
Journal ArticleDOI
Long-term impact of the low-FODMAP diet on gastrointestinal symptoms, dietary intake, patient acceptability, and healthcare utilization in irritable bowel syndrome.
Majella O'Keeffe,Christian Jansen,Lee Martin,Marianne Williams,L. Seamark,Heidi M Staudacher,Peter M. Irving,Peter M. Irving,Kevin Whelan,Kevin Whelan,M Lomer,M Lomer +11 more
TL;DR: This study aimed to assess the long‐term effectiveness of the low‐FODMAP diet following FODMAP reintroduction in IBS patients.
Journal ArticleDOI
Alterations in sleep architecture in response to experimental sleep curtailment are associated with signs of positive energy balance
Ari Shechter,Majella O'Keeffe,Amy L. Roberts,Gary Zammit,Arindam RoyChoudhury,Marie-Pierre St-Onge +5 more
TL;DR: It is demonstrated that changes in sleep architecture are associated with markers of positive energy balance and indicate a means by which exposure to short sleep duration and/or an altered sleep architecture profile may lead to excess weight gain over time.
