Like some of the other posters, it's been up to me to be the model in my relationship with my husband and inspire him to lose weight. I started out quietly, last May--didn't tell him that I'd quit eating sugar, didn't tell him I was working on my diet. After a few weeks he noticed anyways. After a month or so, I suggested to him that maybe he'd want to quit sugar too? And then, miraculously, he did decide to quit.
Since then we've had a focus as a couple on eating healthfully, avoiding sugar and white refined foods and processed stuff, and just being healthy in general. After I started formally exercising in around November, lo and behold, he started doing it too, in December. Together we have now lost around 145 pounds. My husband relies on me a lot to be his nutritional database and let him know what's healthy and what's not, and I gladly take on that role for him, even though (in theory) he's got the same information available at his fingertips on the 'net as I do.
So I guess my advice to you is to inspire and model, not nag and *****. You can't control him, you can't change him, but you can be the best YOU that you can be.
