Just pick one
Shawn Blanc, on making a decision on how to get fit:
Something I’ve learned over time is that when you’re facing a decision and you know you need to act, it’s often best to just do something — anything — and then figure it out as you go.
I can recommend, from vast experience in dieting, to just pick a diet and stick with it. All diets work if you stick to them. Once you get rolling you can try different things if you’d like, but to start the best thing to do is to just begin.
