Marie-Pierre St-Onge

Overview

Marie-Pierre St-Onge is the nutrition and sleep researcher featured in Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge, where she is introduced as a Columbia professor of nutritional medicine.

Current Profile

The current wiki evidence uses St-Onge as a guest expert on reciprocal sleep–nutrition effects. Her profile centers on controlled sleep restriction, appetite hormones, food reward, free-living metabolic risk, dietary patterns, sleep architecture, meal timing, substrate oxidation, and the interpretation of functional-food and industry-funded studies.

Her practical position is pattern-first and qualified: prioritize food quality, plant foods, appropriate portions, and earlier daytime intake without turning one nutrient, oil, supplement, fermented food, or eating window into a standalone solution. The page remains bounded to one structured episode summary rather than a complete biography or publication review.

Key Characteristics

• Studies how insufficient sleep affects appetite, food reward, energy intake, and cardiometabolic outcomes.
• Examines how dietary pattern, fiber, saturated fat, refined carbohydrate, and meal timing relate to sleep and metabolism.
• Distinguishes tightly controlled laboratory results from free-living behavior and longer-duration metabolic outcomes.
• Treats functional-food effects as modest and outcome-specific rather than substitutes for dietary patterns.
• Defends publication rights and statistical interpretation as safeguards in industry-funded research.

Evidence

• Sleep-restriction research - Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge attributes crossover, neuroimaging, metabolic-chamber, and free-living sleep-reduction studies to St-Onge’s research program.
• Diet and sleep research - Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge has her discuss Mediterranean and DASH cohorts plus an inpatient comparison linking self-selected diet to sleep onset and slow-wave sleep.
• Meal-timing profile - Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge presents matched-intake chamber work in which later eating reduced fat oxidation and describes earlier calorie concentration as preferable.
• Functional-food profile - Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge covers null kefir results, sex-specific coffee-oligosaccharide findings, ginger thermogenesis, MCT substitution, and a snack-oil comparison.
• Research-integrity profile - Eating for Better Sleep & Foods that Improve Metabolic Health | Dr. Marie-Pierre St-Onge records her emphasis on contractual publication rights and statistical rather than merely numerical differences.

Qualifications

The source title names Marie-Pierre St-Onge, while its body repeatedly uses “Saint-Ange”; this page follows the title and treats the alternate spelling as a transcription issue. Institutional role, study designs, numerical effects, and funding accounts remain episode-attributed because the supplied note does not include underlying citations or a complete credential review.

What Changed

• Created St-Onge as the guest entity for the Huberman Lab sleep, nutrition, and metabolic-health episode.
• Preserved the name mismatch and study-method boundaries as explicit qualifications.

Relationships

• Huberman Lab - podcast context for St-Onge’s guest appearance.
• Andrew Huberman - host who frames the sleep–nutrition discussion.
• Columbia University - institutional affiliation named in the source.
• Sleep-Nutrition Bidirectionality - central synthesis derived from St-Onge’s episode.
• Appetite Hormone Regulation - hunger, satiety, and food-reward branch extended by her sleep-restriction work.
• Circadian Eating-Window Alignment - meal-timing branch extended by her fat-oxidation study.
• Slow-Wave Sleep Restoration - sleep-architecture outcome discussed in relation to diet quality.
