Using Mets to Quantify Energy Expenditure
The third method here is just aiming to meet the general physical activity guidelines that are provided by governing institutions and medical organizations. A paper by Pearson colleagues from 2018 explains a pretty simple physical activity guidelines. They recommend 150 to 300 weekly minutes of physical activity at moderate met levels between 3.0 and 5.9 Mets. Or they recommend getting 75 to 150 weekly minutes of exercise at what they call vigorous met levels above 6.0 or equal to or greater than 6.0.
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.
