I think we have the same dad! lol I had all my ducks in a row ready to pitch my decision cause I KNEW mine would be weary...my mom had gastric bypass many years ago, and my dad (they divorced long ago) hated how thin and unhealthy she got. So I knew he would be super worried. In fact, I went thru the whole year going thru all the steps and had the surgery scheduled before I told him.

He like your dad was reserved...but he has come around and the more he learned the more he was reassured that it wasn't like my moms surgery. He also knew that fat was going to kill me if I didn't do something.

I am sure your dad when reflecting, and learning will come to the same conclusion. Mine hasn't come right out and said Oh it was great, but in his way he supports me the best he can, and is excited to hear of my losses. At least you got the initial talk out of the way.

BEST of luck.

You are not doing this for your dad. You are doing this for yourself. When he sees how healthy and happy you are he will see that this is the right choice for you. He will come around. Just stay true to yourself and your goal of a healthy and happy life.
