Help! - need ideas for traveling!

You could eat her food just watch the portion size and snack between so your body will not be hungry. Eat healthy snacks, nuts are high in protein. There are bags of snack mix at my walmart by check out (I found them once in produce) for around 1.00 and they have protein and are 130-160 calories per serving. Buy snack bags and make portions so you won't eat too much. Also you could always "help" the cook in the kitchen and bring healthy side dishes that you know will work with your eating plan. Bring salad stuff and ask her if you can help her cook, I did that with my mother in law when we started dating and she loved it, I still help her now and I am always able to give healthy tips too.

I would bring something healthy for breakfast and snacks and eat smaller portions for lunch/dinner. If you fill up on fruits and veggies, which are easy to pack in a cooler to bring with you, it will be easier to eat less at the bigger meals.

When I travel for work, I'll pack along little baggies (pre-measured) with quick-cooking oatmeal, protein powder, craisins and nuts. Then, I just add hot water and eat. That plus a serving of fruit usually fills me up.

Other ideas:
Volunteer to cook dinner one night.
Bring ingredients for a great salad and prep that to eat with dinner. Fill half your plate with salad and take a small serving of her dish.

Just wondering, how exactly does she cook? What does she cook? IMHO, good home cooking is going to be far better for you than a lean cuisine that is going to be high on carbs and through the roof on sodium. Really it's about portion control. I cook a lot and I remember when I first started out on my journey all my friends telling me, "guess you're going to have to change what you're doing in the kitchen huh?"...uhhhh, no...not really...I cook pretty much the same way I've always cooked, I just watch my portions and actually have just a serving of something whereas before my portion might be 2 or 3 servings of something.

My opinion, just eat what is prepared for you and watch your servings. If anything, do your own breakfast and lunch and eat whatever is prepared for you for dinner. Actually, had to have this same conversation with my Mother-In-Law on our last visit...she likes to cook big meals for all three and I had to tell her that I simply couldn't eat that big 3 times per day...had to have my oatmeal in the AM, etc...turns out she didn't usually do that...she only did it when we were there and she was relieved that she didn't have to cook three big meals per day. Perhaps having a conversation like that would help as well.

I liked Bumblebuns idea of bringing fruit as a present - even a gift basket of fruit, or even order something from Incredible Edible's, I think it is, that will make a fruit arrangement. My parents just sent me a box of oranges from Florida.
