You say WW worked for you -but did it really???? Now granted, you didn't gain back the full 70 + some, but none the less you have gained back 50 lbs.
Obviously the best plan in the world, whatever that may be for each of us as individuals will no longer work - if we stop MAKING it work.
So, I think you may need to decide what plan, whether it be WW, South Beach or my beloved CC, you are WILLING TO MAKE WORK - on a permanent basis.
Moving on, I am a cc, like I mentioned. But counting calories alone would have not worked for me - I need the CC along with a focus on whole foods. Where those precious calories of mine come from matter - a lot. I need filling, satiating, nutrient rich, voluminous work for me not against me calories.
Not only do I think a *plan* is essential to follow - whether it be your customized one, like I've done with the CC, but I think it is just as essential to PLAN out your days - your meals and snacks - AHEAD of time. Always knowing where your next meal/snack is coming from. Eating healthy won't happen on it's own - it must be planned out in advance.
Another part of my plan means setting myself up for success by keeping a well stocked home, you gotta have the right foods on hand in order for this to work and keeping my home junk food free - you can't eat it if it's not there.
I look forward to hearing of your progress as you re-start your journey to optimal health.
