What this study is about

LIMITFOOD2 is a randomized clinical intervention study that investigates the effects of two different intermittent fasting protocols compared to a control group on the health of obese adults. A total of 90 participants will be randomized into three equally sized groups: a modified alternate day fasting, a time-restricted eating and a control group, receiving general weight-loss counseling.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.
