Answer 1

Physical activity accounts for 10% of Energy Expenditure. According to the 2018 Physical Activity Guidelines for Americans, adults should engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities.

Step-by-step explanation:

Physical activity accounts for 10% of Energy Expenditure. According to the 2018 Physical Activity Guidelines for Americans, adults should engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities. Increased physical activity not only helps reduce the risk of chronic diseases but also improves overall health and assists in weight loss and weight maintenance. However, it is important to note that less than 10% of our food energy intake is used to do work, with the majority being converted into thermal energy or stored as chemical energy in fat.
