There were several straws for me.
The first was when my mom got diagnosed with heart failre and had surgery at 41. She was also diagnosed with diabetes all at the same time. None of which had to do with her weight out was because she was diabetic for about 3 years and it attacked her heart. Realizing that on top of my daddy dying when I was 11 from a heart attack made me realize that I was not given good odds and if I didn't get my health better NOW that I was next.
Next was stepping on the scale for the first time in a year and realizing I was 300 pounds. I had developed back fat beyond belief I was out of shape. it was like seeing myself for the first time and it made me sick.
So, I decided to stop talking and do something about it!!!
