The Claim

Adding a sleep extension intervention to a lifestyle program including diet and physical activity significantly improves sleep quality and advances sleep timing (onset, midpoint, and weekend midpoint) in adults with prediabetes and short sleep duration (≤6.5 hours/night), but does not significantly improve glucose metabolism or waist circumference compared to lifestyle intervention alone.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In adults with prediabetes and short sleep duration, adding a sleep extension program to diet and exercise improves sleep quality and shifts sleep timing earlier, but does not change blood sugar control or waist size compared to diet and exercise alone.

See the scientific wording

Adding a sleep extension intervention to a lifestyle program including diet and physical activity significantly improves sleep quality and advances sleep timing (onset, midpoint, and weekend midpoint) in adults with prediabetes and short sleep duration (≤6.5 hours/night), but does not significantly improve glucose metabolism or waist circumference compared to lifestyle intervention alone.

Why this might work

When people sleep longer, their internal body clock resets to earlier times, making them fall asleep and wake up earlier, and their brain gets deeper, more restful sleep without changing how their body processes sugar or stores fat.

    In adults with prediabetes who don’t sleep enough, adding a sleep improvement plan helped them sleep better and at more regular times, but didn’t make their blood sugar or waist size any better than diet and exercise alone.
