I would have to disagree with you on the food addiction aspect. I think that while one cannot literally be addicted to food since it is necessary to live, I guess a better way of wording it is that people are emotionally addicted to eating bad foods. It's not an actual addiction like you would think of a drug addiction or alcohol, but it's that need to eat bad food and comfort oneself with those comfort foods. The medical dictionary's definition for addiction is "a persistent, compulsive dependence on a behavior or substance." That pretty much sums up the eating habits of a lot of us here.
It's an emotional connection and to me, that's the tricky part about this "addiction". You HAVE to eat food to live. If someone is addicted to heroine, they don't need it to live. They may get withdrawals when they stop taking it, but it's not a necessity of life. They can stop taking it forever and survive. Those of us who are addicted to food can't just stop eating food the rest of our lives. We have to still eat but we have to make better choices. It's like telling an alcoholic "Okay, so you can drink, you're just going to have to make better choices." Well that's really hard! I feel the same way about a food addiction. In a perfect world, we would be able to say "Okay, I have a problem here, I am just going to stop eating forever." But we can't. I think that's why the sleeve is such a perfect option. It helps us to make those better options and to really keep control of our portions. Going back to the alcoholics thing, it's like we have our AA Sponsor with us 24/7
