If you want to make this lifestyle work for you then YOU need to make that committment. This is a very easy lifestyle to live if you take ownership and control of your diet. Drinking wine is fine if you do it in moderation but if you finish an entire bottle with your husband then how committed are you really? It may sound a little harsh but the truth always is. I'm an Army guy so my line of thinking is pretty straight forward on subjects like this. People, as I used to do, make excuses far too easily and never take ownership. I tell my clients the very same thing I am about to tell you. There are only a few things in life we can control so when you have something than take it by the reins and give it everything you have. Food is the biggest and most important thing outside water that we can control and this is exactly what this lifestyle offers, a way to control. You can still cheat but when you do enjoy it. Savor the taste. It makes those cheat days so much better.
I know its hard to just drop certain things we've grown accustomed to but if you give it just 2-3 weeks of commitment you will feel years younger, look better and have a more positive outlook (weird but true). I weigh now what I weighed in High School 15 yrs ago b/c I took ownership. Now I'll be the first to admit I'm not real sympathetic to most people as my view of the world is a little different but honesty is something regardless of how harsh it may seem will always win out over coddling in my eyes. Again my opinion but this is something I feel very strongly about.
Today is a new day. You will get out of it just what you put into it. If you have made mistakes, there is always another chance for you. And supposing you have tried and failed again and again, you may have a fresh start any moment you choose, for this thing we call 'Failure' is not the falling down, but the staying down.
