Initially, she was in denial about the disease, but now she credits the disease to saving her life. Diabetes has inspired her to eight right and exercise well.
"If I didn't have diabetes, I would probably be at the International House of Pancakes eating a stack of pancakes with butter and syrup. I would probably be 250 pounds. I would not be going to the doctor. I probably wouldn't be married to my husband, Lamar Sally. I wouldn't be healthy for my son, Jeffrey," she said.
She now exercises regularly, eats healthier and is maintaining her blood sugar at the right range. She is not on any diabetes medications and has never felt healthier like she feels now.
In her new book, "Plan D: How to Lose Weight and Beat Diabetes (Even If You Don't Have It)", written with Billie Fitzpatrick, Shepherd recounts her battle with diabetes and how it changed her outlook on life for the positive.
"I feel really healthy," she says. "I have so much energy. I want to live and I'm going to beat this thing. I feel so blessed."
