In adults who have recovered from Cushing’s disease, eating only between 10 a.m. and 6 p.m. for 12 weeks may slightly reduce cortisol levels in the afternoon and evening, but does not change the overall daily pattern of cortisol release.

Effects of Time-Restricted Eating on Circadian Cortisol Secretion and Obesity-Related Metabolic Markers in Cushing’s Disease: A Pilot Study

Cohort Study

Human

2026 Apr 8

This study found that eating only between 10 a.m. and 6 p.m. helped people with Cushing’s disease lose weight and slightly lower their stress hormone (cortisol) levels during the day, without messing up their natural daily rhythm. It suggests this eating schedule might help their body stay more in sync.

Similar Assertions

In adults who have recovered from Cushing’s disease, following a daily eating schedule from 10 a.m. to 6 p.m. for 12 weeks is linked to a substantial decrease in cortisol levels in urine, which may reflect changes in the activity of the stress hormone system.

For adults who have recovered from Cushing’s disease, following a daily eating schedule from 10 a.m. to 6 p.m. for 12 weeks does not significantly alter blood sugar, long-term glucose control, or cholesterol levels.

In adults who have recovered from Cushing’s disease, eating only between 10 a.m. and 6 p.m. for 12 weeks is linked to a 5 cm reduction in waist size, indicating a loss of belly fat without a significant change in total body fat.

Among adults who have recovered from Cushing’s disease but still have obesity, following a daily eating schedule from 10 a.m. to 6 p.m. with slightly reduced calories was linked to an average weight loss of 11.2 kilograms and a BMI drop of 3.2 kg/m² over 12 weeks. This suggests that limiting eating to an 8-hour window might help maintain weight loss in this group.
