People who followed a pattern of eating all of their food across less than 8 hours per day had a 91% higher risk of death due to cardiovascular disease.
That just fails the laugh test. That can't possibly be true.
There is only this published abstract: https://www.abstractsonline.com/pp8/#!/20343/presentation/37...
(which does not contain the 91% by the way; though it is reported widely. perhaps it was in the presentation).
Here is a page with expert reactions (most are skeptical)
