Wife needing advice for her Hubs

Some of the responses remind me of dog training. Positive reinforcement? Praise him?

He is a human being. Talk to him like one. Tell him what you know and back it up with sources. He will decide for himself. All you can do is be as supportive of him as you would want him to be of you.

I disagree. I love hearing my wife b*tch and nag at me all the time. It's really effective in helping strengthen my abilities to tune out the constant verbal diarrhea that she's spewing at me.

Instead of nagging him, try challenging his competitive nature by making weight loss a competitive sport. My wife and I challenge eachother at losing weight, with rewards and punishments to the winner and loser respectively. Offer rewards for progress made and offer him positive encouragement and support when he does something right.

^ This.

Don't nag. My dad is doing C25k because I was relentless about posting my daily run on facebook and my dad likes to do what we do (or have what we have - it's kind of adorable) but when I was talking to him about other areas he wanted none of it, my dad hears things a certain way, if he hears them at all.

I encourage my dad, tell him how proud I am, BUT, I'm easily excited about what I'm doing, so I'll talk to him and say, "Dad, I know this isn't how you want to do it, but I'm so excited I just want to talk about it! Is that cool? No pressure..." and then I rant at him about watching my calorie in take, and my running, and the foods I'm eating and how much better I feel. I talk about how I feel closer to my mom who also uses MFP and how I'm just happier.
