Newsflash: Long, unbroken stretches of sitting appear to carry health risk beyond the daily total of sitting. But breaking them up can help even when the total hours spent sitting number doesn't budge. A listener asked about NEAT -- the energy burned by the movement of ordinary life that isn't exercise -- and the answer turned out to have little to do with calories and a lot to do with staying strong and mobile as we age!

RESOURCES AND SOURCES (some links may be affiliate links)
Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding by Dr. Daniel Lieberman (Pantheon, 2021) — the source of the energy-conservation reframe and the point about hunter-gatherers sitting roughly as much as we do.
Fed Up: What Evolution Reveals About Food, Diet, Health, and Eating Well by Dr. Daniel Lieberman (Knopf, August 2026) — his new book, which we'll be discussing in a future episode.
Move Your DNA: Restore Your Health Through Natural Movement by Katy Bowman (Propriometrics Press, 2nd edition 2017) — the source of the idea that movement works like a diet, with walking as one nutrient rather than the whole menu.
Mentioned in this episode:
Dr. James Levine — the Mayo Clinic researcher who coined the term NEAT in the 1990s while studying weight gain. His best-known study overfed volunteers roughly 1,000 extra calories a day for eight weeks; fat gain varied widely across the group, and those who gained least tended to be the ones whose everyday movement increased to meet the surplus.
Levine JA, Eberhardt NL, Jensen MD. "Role of Nonexercise Activity Thermogenesis in Resistance to Fat Gain in Humans." Science, 1999.
The Stanford fitness tracker study — seven wrist-worn devices tested against lab-grade equipment in 60 volunteers. Six of the seven measured heart rate within 5% error. None measured energy expenditure well: the most accurate device was off by an average of 27%, and the least accurate by 93%.
Stanford Medicine news summary — Shcherbina et al., Journal of Personalized Medicine, 2017.
Sitting time in older adults — reviews of objectively measured sedentary behavior put adults 65 and older at roughly 8.5 to 9.5 hours of sitting a day, more than any other age group, with long uninterrupted bouts associated with cardiovascular disease, blood sugar trouble, frailty, and in some studies higher dementia risk.
Breaking up sitting and physical function — a pilot study in frail older adults found improvements in Timed Up and Go and sit-to-stand scores when participants broke up their sitting, even without reducing total sedentary time.
Harvey et al., "Stomp Out (Prolonged) Sitting" pilot — note this is a small pilot; treat the finding as promising rather than settled.
Movement as a diet — the idea that walking is one nutrient rather than the whole menu reflects Katy Bowman's work, particularly Move Your DNA and Movement Matters.
Two small moves from this episode
● Break up the sitting. Once an hour or so, stand and move, even briefly — refill the water, walk to the mailbox, unload a few dishes. Right after a meal is a particularly good moment, since movement after eating has been shown to soften the blood sugar rise.
● Attach movement to moments that already exist. The kettle boiling, a phone call, a commercial break, a trip to the printer, the end of a chapter. Decide once what the movement will be, and let variety in — balance on one foot at the counter, reach for a high shelf, get down to the floor and back up.
