Adherence

Adherence to Time-Restricted Feeding (TRF) is generally high and well-tolerated, with compliance rates of 65-75% in short-term studies, and greater fasting duration is associated with higher adherence.

If you are worried about sticking to a diet, TRF is a good option. Most people find it easy to follow, with about 7 out of 10 people sticking to it for several months. Interestingly, people who fast for longer periods (e.g., 12 hours) often stick with it better than those who fast for shorter periods.

TRF with 8–12 h of fasting is reported by many studies to be well-tolerated by patients, and surprisingly, the greater the adherence rate, the longer the period of fasting... Studies reported 65–75% compliance during the trial period
