I got nothing on diets. Whatever works for you, works for you. I understand where you're coming from about the food, though, I struggle with the same issue, more or less.

Is there anyway you could find a PCP who you know is covered under multiple plans? A lot of the major health centers in a given geographic region are usually carried by all the major insurance carriers in that given area. Even if you don't feel like there's anything majorly wrong, it doesn't hurt to go in for check-ups in the sense of preventative maintenance. Getting things nipped in the bud is much easier than having major complications to deal with down the road. My last company did biannual health assessments that were available to family members, too. Any chance the DH's company offers anything like that?
