Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study evaluated the effects of intermittent fasting on psychosomatic competence in insulin-treated patients with type 2 diabetes, finding significant weight loss in the fasting group.
These findings suggest that intermittent fasting may be a beneficial dietary approach for managing weight and psychosomatic health in patients with type 2 diabetes, potentially improving their overall quality of life and diabetes management.
Small sample size may limit generalizability. Short duration of the study may not capture long-term effects. Lack of blinding could introduce bias in self-reported outcomes.

Intermittent fasting group lost 4.77 kg compared to +0.27 kg in controls (p < 0.001).
Psychosomatic competence improved more in the intermittent fasting group after 12 weeks.
Subjective sleep quality improved in the entire cohort, but no significant group differences were found.
