I would like to say i'm no MD or Psychologist but i have some suggestions to help you through this if you dont mind reading this post Beside asking her to go on this diet with you why dont you try making dinner with some healthier choices like spaghetti with meat sauce slowly integrate things that are healthier beside using ground meat use ground turkey meat or regular pasta use wheat. There are wheat pasta out there that dont TASTE like CARDBOARD! lol You can also use food in the most intimate ways like feed her strawberries for a snack or cutting up apples with little bit of peanut butter giving kisses in between bites. Sometimes in relationship we have compromise. Relationship are alot of work and even harder to sustain them. But if she supports you like you said then you also should support her in her choices in life. While she choose a cheeseburger and you choose a salad just keep yourself motivated and say to yourself in your own little mind that your closer to your goal.. PEOPLE always say i'm on a diet rather then say your on a diet just make FIRM AFFIRMATION. Affirmation are things you say yourself to help bring confidence like looking into the mirror and say I AM BEAUTIFUL you tell yourself enough you start believing it like people lie to themselves they start to believe the lie is true. The same principle works here RATHER then saying i'm on a diet or life changing goals just say I AM healthy and THIS IS the way i eat. I eat salads because I like them and i enjoy when you start to deny yourself food you like and keep saying your on a diet there is a chance for failure but when you just accept this is how you eat and enjoy eating this way and if you work hard for two weeks you can have a burger with your spouse as a reward. GIVE yourself treat days you need fat to burn fat dont deprive yourself to much. You just make a turkey burger for yourself with some cheese and make her a reg burger and eat together! MAKE IT FUN! DONT MAKE IT a chore!

I know this is a old thread but im currently single and going through this on the opposite end...i cant find anyone to support my goals or interested in living a healthy lifestyle. Im not perfect in a sence where i dont fall off course but to have someone to be there and support and go through it with me would be great.. When i try to compromise it throws me off track and i end up being unhappy. So i just stay single...i hope everyone continues to be successful coupled or not.
