Prediabetes weight loss linked to earlier bedtime, not sleep duration
Fox News • • health
Key Points:
- A study from NYU Rory Meyers College of Nursing found that adults with prediabetes who fell asleep earlier lost about 1.3 pounds more over eight weeks, though causation was not established.
- The randomized trial involved 196 adults with prediabetes who slept less than 6.5 hours nightly, with one group receiving lifestyle education and the other also receiving behavioral coaching to encourage earlier bedtimes.
- While both groups lost weight, there was no significant difference in blood sugar improvement or weight loss between those with sleep coaching and those without, though sleep coaching improved sleep quality and reduced daytime drowsiness.
- Researchers suggested that earlier bedtimes may help regulate hunger hormones and reduce late-night eating by better aligning with the body’s internal clock and metabolic rhythms.
- The study was limited by its short duration, reliance on self-reported sleep data, and showed associations rather than proof of cause and effect; further research is needed to confirm long-term benefits.
