i reaallllyy need some advice !! :(

I'm not quite why everyone is jumping in on the hate wagon towards her boyfriend... I think she was asking for solutions not aggression.

Because I find it quite troubling that he is REQUIRING that she eat a certain amount of a certain food. I don't see any other way to read that than as a 'control' issue.

Now if her boyfriend had simply said that he wanted to go to Pizza Hut and asked her to go with him, that's one thing. That's inviting her to spend time with him in a place that he enjoys and allowing her to figure out a way to have that work into her eating plan. I have no issue with that at all, and frankly, I don't think the OP would either. That is more clearly about enjoying time together while not forcing the BF to totally change his lifestyle or forcing the OP to change hers. Couples do this sort of thing all the time--try to include their partners in activities that are more important to one partner than the other. That's part of the normal give and take of any relationship, even friendships.

But when the BF gives an ultimatum or a decree that OP WILL EAT X servings of Y food, I don't see how that can be read as anything other than a control issue.

Maybe I was too blunt earlier, but this is still how I see the problem and I'm not going to apologize for that.

if you WANT to eat a slice of pizza or even two, by all means, DO! Just figure a way to work it into your calorie allotment for the day. If you think you won't be filled up, try a broth-based soup (low sodium one!) and/or a side salad with a lite vinaigrette dressing or salsa instead of dressing in addition to one slice of pizza. I agree with the idea of letting your slice sit on a paper towel for a bit and to blot off excess oil. Pizza Hut uses far too much oil, IMO.

If you think your boyfriend HAS a legitimate reason to be concerned about your dietary habits (are you under 1200 NET frequently?), he may be going about things in a non-productive way, but try to see the underlying message of concern.

HOWEVER, if you feel that you are NOT having unhealthy dietary habits, his problem may be emotional on his end. He might miss your connection shared over food. He may just like Pizza Hut pizzas and misses out on companionship. He may just feel burned out on dieting-by-proxy. IF this is the case, try reassuring him that you are making healthy choices (give him a run-down on the MFP food diary and how you use it) and that you both stand to benefit from you taking care of your health. HE may not be ready to take this step with his own health and that may be making him feel bad... So many possibilities.

You could say ok to pizza nights every now & then if he promises to go do some fun outdoorsy activity with you over the weekend (bike ride, run, walk, hike, yard work, etc). Explain to him that occasional splurges are fine, but you need to balance them out with something that uses those extra calories and that you like spending fun time being active with him.

Now, IF you feel this is a CONTROL issue, or if you feel put down, under a microscope, walking on egg shells situation you need to reassess your relationship and if its healthy for you or keeping you in an unhealthy place. I hope its not that But always something to throw out there.

Getting to healthy is hard work and it takes a lot of support and love (and self-love!) to get there.

Whatever you decide, best of luck to you on your journey!
