Squishing one's eating into a shorter window, such as one meal a day or 16:8, can lead to improvements even if the diet quality within that window doesn't significantly change.

“if you take their diet and just squish it into eight hours I think like we see people get better like we see people change a lot because as I said we did sort of one meal a day where we squished it even further and those people basically they didn't even change their diet that much we talked to them about it but we didn't focus a lot on it and if you actually probably were to ask them my guess is their diet didn't change a huge amount but just by squishing the time that you're eating you're sort of forcing people away”
