The Claim

Most studies included in the meta-analysis used nighttime fasting protocols rather than strict time-restricted eating with a defined 6–10 hour eating window, which limits the ability to draw specific conclusions about time-restricted eating.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

The meta-analysis primarily included studies that used nighttime fasting, not time-restricted eating with a 6–10 hour eating window, so it cannot be used to determine the effects of time-restricted eating specifically.

Why this might work

When people eat at night, their liver and muscles stop following the body's natural daily rhythm, causing the liver to make too much sugar and the pancreas to release less insulin, which raises blood sugar levels and makes the body less able to use insulin properly.

    Most of the studies called 'time-restricted eating' didn't actually follow a strict daily eating window — they just told people not to eat at night. This study confirms that, saying we need better studies with clear rules to know if it really works.
