My wife and I have been married for 11 years and I had been struggling with my weight for many of those years. Some points of conflict:
1) my wife is an ultramarathoner and nearly everything she eats is carb, often processed carb. 2) Despite being half my size, she can out-eat me by a factor of 3, no problem. 3) My exercise habits are slower (walking/hiking with some weight training) 4) My wife is a great cook, and makes her own bread and ice cream.
Two months ago, we "divorced". We basically talked about our nutritional needs and decided to go our separate ways. I do my own food shopping and cooking. After some experimentation I've adopted a low carb Paleo diet with intermittent fasting. My wife eats how she likes/needs, and she makes her bread and ice cream now only when there will be many other mouths around to consume it. We go out with friends perhaps 1-2 nights per month which I pronounce to be cheat days (beer and the odd potato might be consumed).
Having done this, I am down over 16 lbs without even thinking hard, my energy is great, and keeping at the routine just feels good.
I'm writing this just to pass on the knowledge that just because you are in a relationship that means that you have to try to eat and function the same way. It is important that you do what is right for your body.
Any other stories/experiences along this line?
