In addition to using MET per minutes per week, another option is to use METs to estimate the calories required for an
activity. This can provide a weekly overview;the calculation takes into account the frequency, intensity, type, and time devoted to the activity. The energy costs determined by using METs in this manner will be approximations rather than
precise values. MET values estimate energy costs and do not take into account individual differences in body mass, level of fat tissue, age, sex, movement efficiency, or environmental or geographic conditions.
