The Constrained Total Energy Expenditure Model
There is an upper limit on total energy expenditure that is constrained so that humans don't basically push themselves into a threatening situation where starvation is imminent just because they're highly active. Most people find themselves somewhere between 10 and 50% compensation, but it varies a lot. When we see people who are already very active and burning a ton of calories, when those folks increase their energy or their their physical activity, we see much higher levels of compensation.
In today’s episode, Eric takes a comprehensive look at how physical activity and cardiovascular exercise can impact general health and weight management. Specific topics of discussion include non-exercise physical activity, exercise snacks, step counts, appetite, exercise energy compensation, interval versus steady-state cardio, the interference effect, and practical ways to incorporate non-exercise physical activity or structured cardio into your daily or weekly schedule.
