Okay featherweights, I have a dilemma for which I need your advice. . . .
My weight is just a tad low for my comfort--not terribly or anything, but after I ran this morning it was 119.?, and I'm just not sure someone between five-six and five-seven should be under 120 pounds.
Here's where the problem comes in. I know exactly how to gain healthily, how to maintain a good weight, how to build muscle (studying nutrition right now in school), but my youngest sister was born 11 days ago, so our church is loading our family up with meals people are making for us. While other folks cooking for us is very sweet, often they don't cook as heathily as my mom does, and they bring tons of junk food.
I had NO taste for sweets at school because I was so busy and I knew sweets would slow me down. But now that I'm home, a tiny bit underweight, and relaxed, I'm quite tempted to just eat whatever the heck I want. I did well at lunch today, taking an appropriate serving of the main chicken dish and the creamed corn and then filling up on leftover lettuce, baby carrots, and an apple. But when people like my dad (who's such a sweetheart and not trying to mess me up or anything) says "Oh, but you ran this morning, so why won't you have some pie with us?," I feel so sad, as I watch everyone do an activity as a family that I won't participate in. I'm not every hungry, but I really want to rewind the clock an hour and go have pie for lunch dessert just so I'm not the weird kid who's too much of a snob to enjoy a nice piece of pie.
Does this make sense to anyone? I'm positive the dietary choices I'm making are the right ones, but I hate feeling alienated for my family because of those decisions.
On the positive side, I was really bummed that I quit at 20 minutes before finishing my 5K this morning, but when I mapped out how far I went, I realized that I was less than 1/2 a mile from the end and that I had been running at a 7-minutes and 9-seconds per mile pace!!!!!!!! MAJOR NSV FOR ME!!!!!!! My goal of running a 5K under 20 minutes by my 25th birthday just might be possible after all!

I really wouldn't worry about your weight too much, as long as it doesn't continuously go down. You really aren't anywhere near a dangerous zone, at 5'6 and 119, your BMI is 19.2, which is healthy. A couple of my friends are about 5'7" and 110-115 pounds, and they look great (their my inspiration). Unless you really think you look bad, why gain weight?

Also, you definitely weren't being a snob by not eating a piece of pie, you just weren't hungry. Nothing wrong about that.

You're totally doing the right things, doing great with exercise and trying to eat HEALTHILY, even if you think you want to gain a little (though I agree if you don't want to gain, you sound like you're fine as you are). But the right way to gain isn't to necessarily eat sweets, it's to just adjust your calories in/out ratio to promote healthy weight. Also, I'm sure your dad wasn't offended that you didn't want pie.

Can you participate in "having pie" without actually "having pie?" Like if you offered to make tea to go with the pie, then you could sip a cup of tea while everyone else ate pie -- you'd be together, chatting, enjoying a little something sweet at the end of the meal. Just your "something sweet" would be tea (or fruit, or yogurt or something like that) instead of pie.

Are you just home for the weekend? FWIW, I am going away for a weekend later this month, and while I'm not going to go crazy, I'm not going to worry too much about being on plan. It's two days, and I know as long as I eat sensibly, and get back on plan as soon as I get home, it's ok to eat a little more liberally. (I also plan on being very strictly on-plan for the week leading in). I'm not saying you should do this -- it's just what works for me.

Sub-20 5K -- that's fast! That would be amazing!

To tip the scale a bit here... yes, maybe 119 is too skinny for you. Some people who are 5'6 or 5'7 can look great at 119, but I think it really depends on your body type. I'm 5'5 and I'd hesitate to go under 120. Your BMI is in the healthy range but it's less than a point away from being underweight.
Healthy Range: 18.5–24.9
Your BMI: 19.2
Do you like how you look and how you feel? That's probably the best way to decide what your healthy weight should be.

I know what you mean about the pie. But it can be a slippery slope! A piece of pie can lead to a cookie, and then you might blow your whole day. And you might feel bad about breaking your resolve just to please the others. Then you might resent them for taking you off track and not supporting you!!!! hypothetically

What if you joined in on special occasions only? Then, like thesame7lbs said, you could be strict the week before and eat the pie as a treat. (good idea about the tea, too, thanks).

You're not a snob - you're doing what you have to do to look a certain way and be happy. It's quite possible your family hasn't looked at it that way. I've had to explain my eating habits to my parents (who are food pushers) and it's been difficult. But I won't eat extra just to please someone else. There's a time and place to join in via food.

You saw 119 on the scale once so far? Maybe it's just a fluctuation. You could really weigh 120 but fluctuate from 119 to 121 on a day to day basis.

Good luck with it all. Congrats on the run!

Thank you all for your advice!
I'm feeling better now because something significant happened today.
I failed at my diet.
I really wanted these potatoes au gratin someone made for us, so I had just that and an apple for lunch. According to fitday, that plate of cheesy potatoes scored me 1,200 some calories and over 60 grams of fat.
The important thing is that THAT ISN'T MY LIFE. That was a weird fluke, and there will be other weird fluke meals (ie--Thanksgiving dinner, school banquet, etc.) that will happen. The important thing is I didn't feel good after eating that much (I got 1/2 way through and wanted to quit, but for some stupid reason didn't) and that I'm going to eat light tonight (going to a potluck, so I'll just have veggies and maybe some fruit) and pick things right back where I left them 1st thing tomorrow morning. Plus, I did pilates this morning for 30 minutes and just jogged 1 mile with my dad, so I'm only going to be 200 or so calories over tonight, and I can make that up by going lighter a tiny bit tomorrow and the day after easily.
And Chicksahoy, I'm pretty sure that 119 thing was a fluke--I'm pretty consistently getting 120-122 now, which is better. My goal is to stay under 125, so I'm not too worried about it.

Oh, and same7, I'm home for a whole week (Fall Break), but I did eat pretty much on-plan this whole semester so far, so I'm thinking a week's worth of slightly-off-plan won't kill me .

Hey, I've been meaning to ask -- are you oneofthirteen now? Or were you counting your newest sister when you created your name?

Good realization -- that if you go off, you can get right back! And that one bad meal doesn't even "ruin" your day.

I am one of thirteen! I should change my name!
When I first created the name, I wasn't even counting Naomi Joy. I have one little sister, Abigail Marie, in Heaven (she died at 14 days old from a heart condition). I always include Abigail when I tell people how many siblings I have, so I am now officially one of thirteen!
