Agree with all of the posts above. I have the same problem. My DH is a runner and he has a higher calorie need. I have 3 children including a child who thinks chicken nuggets and pizza should be eaten for every meal. I do a couple of things:

1) Choose smaller portions. I may eat the same thing just not as much.
2) I replace/delete one or two items. For example, I may switch the macaroni and cheese for salad or fruits or just forego the mac n' cheese all together. On taco night, I skip the chips and use greek yogurt instead of the sour cream. I'll make a taco salad bowl with the same ingredients (with very limited or fat free cheese).
3) I flex my calories. If I know DH has a long run plan or on Sundays, I may eat a lighter breakfast or fewer snacks to save more calories for dinner.

All the best!

Tonight I made a lovely chicken stir fry with rice but before I put in the high fat sauce for my hubby, I took out chicken and veggies for me and made a sauce just for my portion with fat-free, low sodium chicken broth, and soy sauce, ground ginger, garlic powder and a bit of cornstarch to thicken it. I also left the rice off my plate. It was doable!
