You've managed 10-15 minutes of new exercise for the past 2 weeks. That's such an awesome start. This primal thing is not a diet, it's for life, right? So even if you just add 1 minute a week, you'll be walking more than an hour in a year's time.
Slow and steady, both in terms of the pace of the exercise itself, and the pace of adding more to it. You'll do great!
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
