I’m not necessarily discounting the results however I found it odd that the primary source didn’t state the sample size (or maybe I missed it)?

> Eleven adults with overweight practiced both early time‐restricted feeding (eTRF) (eating from 8 am to 2 pm) and a control schedule (eating from 8 am to 8 pm) for 4 days each.
That quote doesn’t give the sample size (number of people studied and in each group) though?
