I started eating a low carb paleo diet to maximize my health. Weight loss was never the only goal. Since I viewed this way of eating as a means to both regain and then maintain my health it never occurred to me that I should go back to my old bad habits. I have a kind of mantra:

If you want the results you have to create the causes.

So that's what I continue to do, day after day and year after year, create the causes for maximizing my health.
