Since the calendar flipped over to 2011, I'm noticing people more and more are using this as the artificial beginning of their "diet." They go out of their way to proclaim to the world all of the extreme tactics they are going to employ to reach some mythical goal or finish by some deadline.
I've ridden that rollercoaster. Been there, done that. And from experience, I can tell you two things:
1.) You're never going to do it.
2.) It's not worth doing. Why put yourself through the stress of depriving yourself?
I am convinced that unless you can develop some sort of plan for yourself that is moderate, not extreme and that you can live with....the weight will never be kept off long-term.
I hate the word "diet" anyway. What you need is an eating plan. Positive changes in your life, structure. Go to bed earlier. Eat breakfast regularly. Get off the caffeine. Try to stay away from fast food.
Because if you can't do it for the rest of your life, it's a huge waste of time.
