Fitness on the Way to Becoming a Vital Sign

December 2, 2016 — It’s about time. A new scientific statement from the American Heart Association recommends that “at a minimum, all adults should have CRF (cardiorespiratory fitness) estimated each year” during health exams. The rationale is pretty compelling: A growing body of epidemiological and clinical evidence demonstrates not only that CRF is a potentially stronger predictor of mortality than established […]

Fitness Trackers Work – For Fitness

September 28, 2016 — Last week, JAMA published a randomized, controlled study that showed fitness trackers don’t help people lose weight. This week, Obesity published a systematic review and meta-analysis of how well fitness trackers work for their intended purpose – promoting fitness activities. Surprise, surprise: adding a fitness monitor to fitness programs seems to yield more physical activity. Herman […]

This Is Why They’re Called Fitness Trackers

September 21, 2016 — A new randomized, controlled study published yesterday in JAMA found that fitness trackers added to a 24-month weight loss program did not help with weight loss. In fact, adding them actually resulted in less weight loss. People in the control arm with a standard weight loss program lost an average of 13 pounds after 24 months. […]

Does Exercise Save Money?

September 9, 2016 — The American Heart Association is promoting an analysis from its journal that suggests regular exercise can save money. In fact, the authors of this study find that medical expenses are about $2,500 lower annually for people who meet current guidelines for regular exercise. That’s at least 30 minutes of moderate exercise five times a week. The […]

Rethinking Unsubstantiated Nonsense About Energy Balance

August 28, 2016 — For decades, the common dogma of energy balance stated that weight gain or loss is a simple matter of “calories in and calories out.” On the second day of YWM2016, Steve Blair called for a rethinking of “nonsense presented repeatedly without any data to back it up.” At the top of his list for such nonsense, he […]

Shaming in the Fitness Culture

July 17, 2016 — A fitness culture is spreading around the world that has great potential to promote better health and well-being. But even a small element of shaming can undermine all of that. Look at fashion, look at daily routines everywhere, and the fitness culture is impossible to miss. While much of life has become a sedentary ritual of enslavement to glowing rectangles, […]

How’s That $3 Trillion Fitness Industry Working for You?

May 7, 2016 — The $3.4 trillion fitness industry has prospered because it has come to represent an identity for the people who participate. In an interview with Marketplace, Bloomberg’s Jason Kelly explains: What is so interesting about it, I think, is this idea that it has moved from activity to lifestyle. Once it moves to a lifestyle, then […]

Exercise Strategies: Tortoise vs Hare

April 29, 2016 — Maybe slow and steady is not the only way to win the race for better fitness. A new, carefully randomized, controlled study in PLOS One finds that that one minute of intense physical activity in a ten-minute routine can do as much to improve your fitness as 50 minutes of more moderate exercise. Researchers from McMaster […]

Sneaky Bias in the Realm of Obesity

March 29, 2016 — Sneaky bias has an annoyingly persistent way of creeping into obesity research. A case in point appears in Mayo Clinic Proceedings in a study that we reported last week. Though we mocked the proposition that only 3% of Americans have a healthy lifestyle, we did not call out the flaw in the study that led to this […]

Fitness Trackers: High Tech Placebos or Coaches?

March 25, 2016 — It’s hard to tell whether fitness trackers will turn out to be high tech placebos or coaches. Everything you read talks about promise and short-term outcomes — along with tech companies jostling for a competitive advantage. It’s pretty clear that physical activity monitoring technology offers plenty of promise and plenty of unfinished business. A research letter published […]
