Can a 10-Hour eating window and lighter foods beat insulin resistance?
NCT ID NCT06259435
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether eating only between certain hours (a 10-hour window each day) and choosing foods that are less calorie-dense (fewer calories per bite) can help older adults with obesity and insulin resistance. Forty participants followed this eating pattern, and researchers measured changes in insulin resistance, body weight, and other health markers. The goal was to see if this approach could improve how the body handles sugar and help with weight control.
