Welcome Jennifer! Glad to have you here with us! I TOTALLY feel your pain in regards to the DH situation.
Long story short, my DH is also overweight. We lost weight together in 2003 (me on WW, him on Atkins). I lost 41, he lost 60+. We both kept most of it off for most of 2004 and into early 2005. Then we both fell "off the wagon" so to speak, and he gained all of his weight back (and maybe even more.) I gained 20 pounds back, which brings me to early 2008, when I decided to get back on track and recommit myself to the healthy eating of WW. I have lost another 51 and have 19 left to go. DH, unfortunately, didn't learn anything from Atkins... no portion control, no healthy habits, not fruits and veggie, etc. So he has no choice at this point but to either go low carb again, which I think is very difficult to maintain for a lifetime, or LEARN a new healthy eating style (such as WW), but of course he hasn't chosen to do this.
It is hard enough to eat healthy when the kids snacks are around... but add in DH's love of ice cream, real popcorn (which he makes EVERY weekend... loaded with butter), beer, and fast food, and it is nearly IMPOSSIBLE sometimes to stay on program. But I am committed to doing this, not just for myself, but to set an example for my kids (especially DD) and for DH. I am hoping that my success will encourage him to do something about his weight. But I cannot even SUGGEST that he do it... it has to be his idea... not just because it is a mental thing to get ready to change your habits, but because he HATES being told what to do!! Any suggestion from me would be met with resistance.
OKay.... so my story wasn't short!

Good for you for restructuring your eating habits. It would be so GREAT if you could get off of some of those medications. It would seem likely that if you got your weight under control that the GERD and diabetes would improve, and probably also your blood pressure. You have SO MUCH to motivate you regarding your health issues (not to mention what is must be costing you at the pharmacy every month!). You CANNOT let DH's food problems affect your weight loss journey. But it will be tough. I'm sure your doctors have told you to lose weight.... but you can't do it until you are ready in to do it for yourself... and perhaps your DH is not at that stage yet. All you can do is set a good example, offer assistance when needed, and maybe he will get on board eventually.
Again, welcome to our little group. Let us know if there is anything we can do to help. Several of us are also on WW, so if you need food ideas, points, or whatever, let us know............................P
