What is considered a minimal benefit level of physical activity in MET hours per week?

A minimal benefit level of physical activity is generally recognized as being in the range of 10 to 20 MET hours per week. This level of activity has been associated with significant health benefits, including improved cardiovascular health, weight management, and enhanced overall wellness. The MET, or Metabolic Equivalent of Task, is a unit that estimates the energy expenditure of physical activities compared to resting metabolic rate.

Achieving this level of activity generally involves engaging in moderate-intensity exercise, such as brisk walking or cycling, for at least 150 minutes per week, or high-intensity activities for a lesser duration. Research supports that accumulating these MET hours contributes positively to reducing the risk of chronic diseases and improving mental health.

While lower levels of activity might still provide some benefits, the 10 to 20 MET hours per week threshold is recommended to enhance health outcomes significantly. This range balances accessibility for most individuals and the necessity for consistent physical activity to promote a healthy lifestyle effectively.
