Got this question on a recent post and wanted to answer it here too!
We do recommend a 12-14 hour fast overnight for metabolic health. That could be as simple as finishing dinner by 6 and eating breakfast around 7 or 8. Most of it happens while you’re asleep.
Where we pump the brakes is going past 14 hours, especially for women. Our hormones are really sensitive to not getting enough energy, and longer fasts can bump up cortisol, throw off your cycle and thyroid, and cost you muscle.
More isn’t better here. If you want help figuring out what timing works for you, that’s what we’re here for. Link in bio
