Having trouble eating enough for my goal today, Help!

OP- I always turn to peanut butter too teehee..

I have my goal set for around 1900 and eat my exercise cals back so I regularly eat 2,300- 2,500 a day.. woot woot! MFP builds in your deficit so even eating back the exercise cals you are still at the same deficit as you started the day with..too big of a deficit leaves your body cranky...well, it leaves MY body cranky hehe It's good to refuel the machine after such a big burn.

10k is what like 1000 cal?

like 600-1200 depending on how large you are

How tiny would a person need to be to burn only 600 calories on a 10k run?

I am wondering the same thing......Do I really need to eat up the calories that I burn off at the gym in the evenings. I am trying hard to get this last 40 lbs off and not gaining a lot of ground on it. I had originally started at 285 and lost 80 lbs and came to that plateau and could not get past it. All I did to loose the weight was to walk everyday for an hour or more, plus portion control, cut out the breads and such and ate healthier... But I gave up last summer and put 40lbs back on in not time at all. Now I am back on this again and I am back down to 225 and bouncing between that at 227.... Asisde from starving myself I am not sure what to do anymore....
I am at the gym everyday and track every bite that goes in my mouth.... I am afraid to go back up to 285 if I am suppose to eat up the calories I burn at the gym...

This is just me, but on days I work and or do weights I am starving and actually need my calories or even a little more. Days I do cardio (even when I work, worse when weekends) I can't eat them all back. I think if you eat more then the minimum net, for us girls it's 1200, you should be okay. But if you are hungry the next day, don't stress if you go a little over your net. On that note, if you really feel like a beer or some sort of treat have it and enjoy it . Way to go on the 10 km run

The 1200 minimum isn't just for women. It's just the minimum MFP will let you put your goals at...especially if you choose sedentary and pick a 2lb/week loss because you are trying to lose weight as fast as you can. If you are wondering what you should be eating at...here's a link to find your TDEE. And MFP's #s end up very different because they expect you to eat your exercise calories back.

Full fat/2% milk, starchy vegetables like peas and sweet potatoes. Integrate whole grains like pasta, wheat berries, and barley into your diet just to name some things that have not already been mentioned.

It is important to eat back your exercise calories instead of going by hunger alone. When you do high intensity activities like running 10k digestion gets a bit out of whack. Personally, when I'm on hiking trips or on long run days, I have to force food into my mouth. You may not be hungry, but your body NEEDS the calories, protein and nutrients to repair itself.

For those curious about the op's calorie count, my so is a long distance runner and roughly 200 pounds and eats roughly the same amount while losing weight. It really depends on how large you are and how active.

Typically I do not agree with drinking your calories--but whats one beer, right!?

Blasphemy!! I run and ride mostly to be able to drink.

A bottle of wine goes a long way towards filling those calories. Cheesecake works too. Ice cream with nutella?
