Toward a useful physical education

We have widespread ill health. And in the US 42% of us have become obese. PE didn’t help most people.

Entertainment, porn, and sports show us buff physiques to consume. We prominently reward athletes. And advertising sells us convenient food.

We train people to external direction. Our received ideals of fitness come from military preparedness. And we measure and praise performance. Why?

Ill health increases. And the fitness industry grows. This is not working. This fitness does not help most people.

We are going to spend too much time sitting. We are going to look at screens a lot. How do we teach ways of moving as lifelong harm reduction?

Hope

We must teach hope because without it everything else we can teach won’t get used.

Fatness predicts decreased physical activity and increased sedentary time, but not vice versa: support from a longitudinal study in 8- to 11-year-old children | International Journal of Obesity

Our results suggest that adiposity is a better predictor of PA and sedentary behavior changes than the other way around.

The carbohydrate-insulin model: a physiological perspective on the obesity pandemic | The American Journal of Clinical Nutrition | Oxford Academic

Calorie restriction for obesity treatment results in weight loss—initially—giving patients the impression they have conscious control over their body weight. But predictable biological responses oppose weight loss, including decreased metabolic rate and elevated hunger. Therefore, ongoing weight loss requires progressively more severe calorie restriction, even as hunger increases. Few people achieve clinically significant weight loss over the long term with this approach. Those who cannot might feel implicitly stigmatized as lacking in self-control.
