Intermittent fasting performs about as well as traditional calorie restriction for weight loss. Dr. Courtney Peterson thinks that’s a win: people can naturally eat less without constantly counting calories or practicing portion control.

Why do intermittent fasting studies contradict one another? Dr. Courtney Peterson points to a surprisingly simple issue: many trials shorten the eating window by only 1–2 hours. The clearer effects tend to appear when the window changes by 3–4 hours.

Dr. Courtney Peterson once thought intermittent fasting might selectively increase fat loss while preserving muscle. Then she tested it. Her team found no evidence for either effect, despite looking at the data multiple ways. 📺 Watch on YouTube: youtu.be/dKauIgX3IH4

An 18-hour fast barely raises ketone levels. Dr. Courtney Peterson explains why meaningful ketosis generally requires much longer fasting, and why ketosis is unlikely to explain most of the benefits of daily intermittent fasting. 📺 Watch on YouTube: youtu.be/dKauIgX3IH4

A man’s wearable data began changing roughly four and a half months before his death. Resting heart rate, HRV, gait, sleep, and activity all shifted. No system recognized the combined pattern or sent an alert to him or his physician.
