Story summary

The ChronoFast study from the German Institute of Human Nutrition and Charité found no health improvement.
It enrolled 31 women over two weeks, comparing early (8 a.m.–4 p.m.) and late (1 p.m.–9 p.m.) eating windows with constant calories.
Results showed no significant changes in insulin sensitivity or other metabolic markers.
The findings imply benefits reported earlier may reflect unintended calorie reduction and emphasize energy balance.
