I need to get healthy!

I am a 32 year old mom of 2. I have been married for 10 years. I own a dog grooming business. I am addicted to food! I am horrible with intros.

Currently I am at my highest weight ever. After having a hyst at 26 my weight just kept going up. Although I would love to lose the flab, my biggest concern is my health. i don't want to need a knee replacement by 40. Currently I'm at 219 and would love to see 160.
