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.

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.

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.

Some people with high levels of cortisol in their blood do not show the typical physical signs of Cushing's disease, such as weight gain or bruising, which may be due to their bodies converting less cortisone into active cortisol in tissues.
