My body doesn't like protein?

My whole life, I've been a carb-y person. I ate soups, vegetables, mac & cheese, pasta, etc...and got most of my protein from dairy. I was not a meat eater - chicken was probably the only consistent meat I ate, and I would eat it maybe once a day and have 4oz (MAYBE). I'd rarely have a steak or hamburger or fish. I was always moving around (biking, softball, dance) and always thin. When I hit my 20s, I started working out here or there, but never had a problem staying thin.

Around 28 years old, I met my future husband, and I started cooking for both of us rather than just me. He "must have meat" with every meal. I started having to make chicken, meat dishes, fish, etc. Within 6 months, I started gaining weight consistently. Even if I was eating healthy, I'd still notice an appreciable difference in my weight. As soon as I'd drop the meat from my diet (or limit it to a few slices of chicken or bites of fish), I'd start losing again. Of course, it was a sick cycle because husband would still demand meat, and I'd go back up again.

Now that I'm trying to lose a solid 40 pounds of "lethargy and meat-eating weight, I'm trying to really focus on my meals. Pretty much everything I read everywhere talks about how important protein is to losing weight and building muscle, and 9/10 times the suggestion is meat. Since my primary exercise right now is jogging, I don't really feel like I need meat to SURVIVE (though when I was doing strength training regularly, I'd crave steak or another heavy protein at least once weekly).

My question is, are there people whose bodies just don't LIKE meat? I don't mean having an adverse reaction to the meat (indigestion or intolerance), but whose bodies just don't retain weight properly when they eat meat, and prefer carbs?
