I struggled with this. Then I decided that for me to keep it to myself I was placing shame where shame didnt belong. I was worried about being judged, about how others would feel about it. Then I realized that the only opinion that mattered was mine. I share my story with everyone. I talk about it here, I make freaking youtube videos about it. I have 3 other people I know right now who are morbidly obese and never considered surgery until they saw me do it. All 3 are considering it themselves now. If even one of them takes that step and gets healthy then every single negative comment I have heard will be worth it.
I am very open about my journey before and after weight loss surgery. But that is ME. I understand that some people are more private, and there is nothing wrong with that....as long as you are doing it for the right reasons. If you are doing it because you are private, great! If you are doing it because you are ashamed or guilty about your decision to have surgery...then that would worry me. It makes me sad to think that there are people who feel shame over their decision to take back their lives. There is no shame in asking for help, or in realizing that you need a new tool for the job.

I do have to say one more thing about it. If you are telling 300 pound people that all you did was eat right and walk...then I do think it is wrong. It is feeding into their failure mindset. How could they not feel even more like a failure when someone who was once like them is now thin and fit and all they did was follow a diet? I know it used to make me feel like a failure. The fact is that I needed this surgery, and there are others that do as well. If you dont want to tell them the full truth then it is kinder not to answer the question at all. I hope that doesnt offend anyone.

Is it wrong not to tell? No, because that implies there is some sort of justified moral judgement that other's have the right to infringe upon you relative to your choices.

You have to ask yourself a few questions:

1. What right does anyone have to know the finest details of your health and welfare decisions? Would you be asking this question if they wanted to know why you had a cancerous breast removed or your gallbladder out?

2. If you're happy with your decision, and you're dieting and exercising--just like everyone else in the world who wants to be thin and tone--what difference does your WLS make in the big picture other than giving you an extra weight loss tool? Face it, without the good food choices and consistent exercise, nobody's WLS keeps the weight off all by itself.

3. I'm in the best health and shape of my life right now and I have no intent of ever "going backwards". Anyone who doesn't like that I had WLS or holds an opinion of my choice as being the "easy way out" is invited to run with me on any of the 5-6 days I run each week for 4-10+ miles each run, and explain to me in detail why what I did was the "wrong" choice and "easy way out". Sarcasm intended.

My point is, you deserve to be the best you can be. Your choices are yours and anyone who has an issue with that concept can blow off because God knows, there is probably plenty of choices they've made you could take issue with.

Now go and worry no more!
