(12:35 – 12:48)
But, for example, I’m probably eating 14 hours a day. Not every day, but there’s definitely a whole bunch of days when I’m eating 14 hours. I’m understanding from quite a few scientists I’ve been talking to recently that’s probably not ideal.
(12:48 – 13:13)
But on the other hand, I think you’re definitely not sitting here saying people should eat all their food in four hours. We don’t have big enough studies in a wide enough group of people and not enough particularly women in our studies, although we were lucky in the majority were women in the Big If study. But it looks like the sweet spot for when the results start sort of turning significant is around at this 10-hour eating window.
(13:13 – 13:21)
So if you can get to 10 hours, that’s fine. There’s some evidence that maybe 11 could be okay. And there’s probably differences between people.
(13:21 – 13:33)
So we’re talking averages here, which might vary at different ages and between men and women. We don’t really know yet those differences. So at the moment, I think it’s do something that’s sustainable.
(13:34 – 13:48)
So if you can have a 10-hour eating window that appears to be sustainable for years because it’s what our ancestors did, that’s pretty easy. But for some people, they might want to get it down to eight hours. Others might be okay at 11.
(13:48 – 14:02)
And to flip it on the other side, my sense from you and Sarah and others is like over 12, you seem to be saying like I’m really skeptical that that is a good thing for you. Correct. I think that’s right.
(14:02 – 14:20)
All the data suggests that there is a linear relationship between how long you can do it for and in terms of the biological benefits. But at the same time, it gets harder to do it for most people. So it’s this trade-off of where these two lines go.
