Mr. McMuffintop joins the party?

Although Mr. McMuffintop has essentially been offered a new position with a new company, in order to officially be hired he has to pass a background check and physical.

For the most part, Mr. M is healthy and in decent shape.  Even at my heaviest weight of 208 lbs. he could easily pick me up (now he can pick me up and flip me upside down).  However he has a little belly and has known for a while that he should lose a few pounds.  He was pretty upset a couple of years ago when his pant size went from 34 to 36, but as time passed he became used to the new size and hasn't thought much more of it.

Well after having his physical yesterday, he now realizes that he needs to jump onto the weight-loss train with me.  At 5'9" his weight is just under 230 lbs.  That puts him at a BMI of almost 34.  He was pretty shocked to learn that it means he is obese. 

I've known that he was considered obese, and gently mentioned it when I first started my weight loss journey in January because I thought he should try to lose some weight too, but at the time I don't think he really wanted to do the necessary work (a mindset I've been in many times myself).  I didn't pester him about it because, as I know by experience, it's something that one has to decide to want to do for one's self.

But I am hoping that hearing the words from a doctor he is serious about wanting to lose weight with me now.  Mostly for his own health and well being, but also selfishly because it has been a real struggle every time he comes home from work to manage my own attempt at weight loss.  I know that the food I put in my mouth is my choice, but it's really difficult to choose not to eat bad things when they are constantly in front of me for two weeks at a time.

We have tried to lose weight together before and at the time it made me miserable.  You know, the whole "guys-tend-to-lose-weight-faster-than-women" thing.  But this time I have a good head start, so I feel positive about doing it together again.  In fact, I welcome it because it will help keep me on the right path.

Anyone else trying to lose weight with their significant other?  I'd love to hear tips on how you manage to do it together or issues that cause conflict.
