People w/ TONS of calories "remaining"??!?!?

I usually bank my extra calories for the rest of the week b/c I work on a weekly deficit, not a daily deficit. Also I have big calorie burns on the weekends, sometimes 800-900 cals each day. It doesn't make sense to me to stuff myself trying to meet my daily calorie goal when I can use them to help average out my weekly caloric goal.

This is what I do too! Weekly i have one meal planned that is exactly what i want ~ pizza, real burgers with cheese etc... Probably closer to maintenance calories than weight loss calories. So i bank a bit during the week.

For me, a small change can mean difference between staying under & using every last. For example, skinny cow ice cream sandwich = 150 cals or jolly rancher = 30cals. If I'm not hungry but want sweets i have jolly rancher . Also the week after food shopping is a lot of salad & fresh veggies which tend to be lower cal then rice heavy dishes i make later on as the fresh stuff is used up.

Over on fat: clogged arteries, heart disease; over on protein: can adversely affect the liver especially if you are not young.

Not really. Going over your fat and protein macro isn't going to hurt you, if you are otherwise healthy.

I eat 1800 - no exercise cals.

Sometimes I'm under by a couple hundred, sometimes I'm over.. That's life. I do not deliberately try to be either. Sometimes if I get busy or distracted I will just not eat and end up with a pretty big hole but invariably sometime during the week I will have a day when I am just famished and can't feel full no matter what I do, so on those days any deficit that I 'did' have gets annihilated in short order.

This is how it is supposed to work. Life is not the same every day, sometimes you aren't hungry, sometimes you get surprised with a dinner out and end up having a really 'good' night full of really BAD choices. I don't regret my choices because in the end it all works out and as long as my choices are more good then bad I will continue to lose weight.

Now, this being said having a big deficit every night is not good.

That would happen to me if I logged my exercise. Right now, I have my calorie goal set higher, at my TDEE - 20%. If I actually logged my exercise, I would have calories remaining because I don't intend to eat back exercise calories right now.

My macronutrient ratios generally leave me satiated enough.

I sometimes have 3 or 4 hundred left over, though I will have a treat sometimes if that's the case.
I eat huge amounts of food, mostly vegetables, although I do have some carbs, usually for breakfast, and treats, often in the evening.
I try to leave some spare calories, - as someone earlier said I don't always trust my exercise calories and would prefer to act on the side of caution.
And the weight is only coming off slowly.
Too slowly!

If this is the case with me, i usually either get a protein/cereal/chocolate bar or some icecream! Getting a treat at the end of the day is always lovely

Some days I can eat like 1500 and have 300 remaining (my goal is 1800) and feel like i have eaten loads. Over days like friday and today i feel like i haven't eaten much at all and im at 3000 calories.... really just depends on the day!

I often have truckloads of calories left, especially on days when I swim 3 hours. My "fat" Dr. told me not to eat them back, so I usually don't (I could not possibly eat them all unless I mainlined chocolate).

Sometimes I have extra calories at night because I work out late...but then I always eat them the next day.

I find that exercise is the biggest reason for me having a gap in my calories.
I never take a taxi or bus to anywhere, I just walk and I'm also fortunate in the sense that I as part of my degree, we end up doing a lot of exercise so I build up the calorie deficit quite quickly

I sometimes have a few hundred remaining, mostly I think it's because MFP over calculates the calories that I burn while exercising. I still log it because I want to keep a record of them, but I don't always eat them all back. Also, it may be because I slept for 12 hours, and therefore am not really hungry enough to eat all my food in a compressed period of time.

I've had 3000+ calories to eat with only a couple hours before I had to go to sleep.

You don't have to eat them all the same day, you can save some for the next day if you want. There are no rules that say you have to eat them only from 12am-11:59pm only.

Keep it simple.

I have the same problem! If I'm not hungry, then I let it be. My body will let me know if I'm hungry. If I'm hungry then I'll make something.

Most times I have 100-500 calories left over. I try to eat 1000 calories per day and exercise off 1000 calories per day. If I try to eat more than the 1000 I find myself battling too much fiber (stomach dislikes too much fiber), too much sugar or too many carbs. I'm trying to work in my blood sugars so I have to limit what I can consume. Am I hungry? Not overly, but am definitely ready for breakfast the next day! My FD is open to the public. I would welcome advice from others about how to improve my plan.
