where else would I go?

So, recently I thought about quitting and giving up (we all think about it right?). But I realised that I literally can't quit. I mean what else would I do? I have become convinced of the simple truth that what you eat increases your mass and what you do spends it. Its a simple economy really, and the points system helps you measure the approximate value of each item in and out. And I now know its true. (why did it take me so long to get this? its not rocket science!)
It can be hard sometimes, controlling what I eat and realizing its value, motivating myself to be just a little more active and working at good nutrition. But are there really any other options? Its a simple fact of creation, that's the way the body works. Its just the truth. And now that I've figured that out I can just relax into living a lifestyle that reflects the truths I have learned.
Sure I could quit paying my WW membership. But that doesn't change the math of what I put into my body - minus activity = net gain or loss. Other diets might boil down to this same principle, some don't (!), that's why they don't work.
So there is no way for me to quit. :)
Kinda reminds me of what Simon Peter said to Jesus after many of his followers started abandoning him. Peter had become so convinced of the simple truth that Jesus' was the saviour sent by God that he answered : "where else would I go? you have the words of eternal life!"
Once you know something is the truth, either you start living it or you play games and try to ignore the truth, hoping it will change.
