<human>: Can you give me a shortened version of the text?

Before I get backlash for wanting my husband to loose weight, here's some background info. Since we have had our son a year ago, we both have gained 20+ pounds.  While I like my husband the way he is he lost quite a lot of weight right before we met and he was very happy with his results.  He went from 200 something to about 185. He comments a lot on how he thinks he's getting fat, and doesn't like the way he looks in his clothes.   For a while we both have talked about being healthier, especially now that we have a kid that will look up to us.  He also has sciatic nerve issues and was directed by his doctor to loose weight to help that. We never really put much effort into it and continued our late night snacking and whatnot.  Well I have really been trying to change my diet and work on myself.  While I don't want to force him to do something he doesn't want to, I just want him to be happier with himself and encourage him to do better.  I've cut out my late night snacking and started to think more about what I eat.  I even started working out.  He on the other hand, is still eating really fatty things and eating late at night.  I don't want to make him insecure or feel bad about it, but he's the type of person who will stick with something if it makes him happy.  That happens to be pop tarts at 2 am.  So how do I approach this situation, if at all, to encourage him to want to make better decisions?
<bot>: husband and I both have gained weight.  Now we want to get healthy.  I'm trying but he isn't.  I don't know how to approach the situation without making him feel insecure.
