doing the minimum effective daily dose

Options
I found this article about sustaining healthy lifestyles over time (essentially modifying your lifestyle) This is what we are doing. Bravo. Here is an exerpt "What is M.E.D.?
Doing the Minimum Effective Dose means doing just enough to move the needle and improve your health, fitness, and body shape as you get older.

And then not trying to do any more than this because it’s unsustainable.

For folks over 40, it is better to nail this MED week-in week-out than to only manage to do something much higher maintenance for 6 weeks, while hating life, being desperate to stop, and eventually giving up and doing nothing for months.

Think about it.

From a purely mathematical perspective, it’s better to do:

2 workouts per week for 52 weeks (104 Workouts) than
5 workouts per week for 6 weeks, 3 times a year (90 Workouts).

Similarly, it’s better to: lose on average 1lb/0.5kg per week for 52 weeks (52lbs/26kg total fat loss) than

3lbs per week for 4 weeks (-12lbs) with severe calorie restriction, then gain that weight back (+12lbs) because you give up (0 total fat loss)."
