In order to figure out how many calories we should eat each day, we need to know how "active" we are. Every source I've seen defines active as follows:
a) Sedentary: Very little or no exercise at all
b) Slightly active: Light exercise between once and three times per week
c) Moderately active: Moderate exercise three to five days per week
d) Active: Intensive/heavy exercise six to seven times per week
e) Very active: Very heavy/intensive exercise twice a day
None of those describes me! I'm 55 years old, so everything I do would be defined as "light" by most peoples' standards, even though it feels intensive to me. Simply put, I'm no longer capable of heavy. But I exercise at least 2 hours each day, each and every day. That includes walking, swimming, lifting weights (not very heavy!), etc. Thus, in terms of how often I exercise, I fall in the very active category...but in terms of how intensely I exercise, I'm only in the slightly active category.
So, should I just split the differences and assume I'm "moderately active"? Or do I stick with only "slightly active" because all my exercise is light?
