David and I were married about 12 years ago. Since that time, we have probably put on about 100 pounds, with me putting on the bulk of it. The same thing has happened to my son and his wife. We've been together for about two years now, and I've gained about 25 pounds, and he's gained about 100 pounds. I'm worried about Danny's health because he's gained so much weight so fast.Amy

Dr. Phil: Let me tell you guys, the hardest thing I think people face is when you try to do this by will power, because it's the first of the year now, and everybody is excited. And, "Come on, we're going to do it."

I got some new jogging shoes, and I put them on the porch, and the damn things just won't jog. They just won't go. You can't do it by will power because the middle of February, it's going to be cold, and you are going to be sick of it. And you are not going to want to do it.

The only way you are going to succeed is if you change your lifestyle, and you set up your environment to program you for success. You got to make an appointment with yourself every single day, and you got to keep it, and you have got to have accountability to someone besides yourself.

Clean up your environment. You can't eat it if it's not there. The chances of you driving to 7-Eleven to get some Oreos is pretty low, but if they are on the counter, they are history. You know it and I know it. So, you've got to program your environment, and set up a lifestyle that pulls you up when you don't. The question is: Are you going to do it when you don't? Are you going to avoid those foods? Are you going to exercise? Are you going to do the things you need to do?

And lastly, let me tell you, to set a realistic goal. Right now, an overweight Body Mass Index is 25. A guy like you, if you get down to 25, you're going to be underweight. Don't do that. You're too big. Pick an ideal body weight that's realistic and go for that. So, don't try to get back to where you were when you were 17 because you are not, I'm sorry.
