How am I supposed to eat 1500 calories tonight???

Can't say I ever have that problem!

It won't be a big deal if you can't eat more tonight. But in the future you: A. shouldn't burn that many calories exercising, it's too much for your body, and B. try to estimate the amount of calories you'll burn and work them into your meals earlier in the day.

I have been in your position a few nights ago, since my daily calorie limit is 1,000.. and I usually only eat 400-900 per day... then I workout an hour, where I burn 1,007 soo that leaves me with a huge deficit.. but I never thought of eating then again.. lol

Like today I only ate 900, and im about to workout for an hour an burn 1,000 !!

you don't need to eat that much! working out gives you the extra calories to eat if you want to stay the same weight. I'm guessing you are trying to lose weight. Do not eat that many calories!

False. MFP is set up so you can lose weight WITHOUT exercising. Your initial goal is already set at a deficit so you can lose weight. Exercising is a bonus. Your net calories should never fall below 1200 for a woman (1500 for men). Your body can't function on less than that.

It won't hurt you if this happens just once, but as NoAdditives said, try to plan your exercise calories into your meals and snacks so this doesn't keep happening. You don't have to eat ALL your exercise calories back since your initial goal is 1600, but you do need to make sure your net stays above 1200 if you want to lose weight and stay healthy.

You really should read this article (warning: the entire thread may take you a week). I am afraid that you are setting yourself up for failure by not eating anywhere near the calories that your body needs.

Just an FYI and I hope that you are successful

A is not a ridiculous statement. Of course, you can't spell ridiculous so I doubt there has been a formal education in this regard.

There a huge number of physiological responses to exercise stress. And, guess what, you can only take so much of it (especially when resources are scarce). In fact, there have been plenty of studies that suggest any time spend over 60 minutes actually DEGRADES muscle and serves no benefit.

Sorry for attacking you, but the misinformation on this site is just hugely abundant and I'm entirely sick of it.

- 2pts for heckling the typo
+3 pts for that golden nugget of information.

Truly good information, thank you!

I disagree. they suggested I ate 1370 and that is way too much for me to lose weight. I had to adjust to 1200 which is more practical.

Not necessarily true either. If you are small to begin with, and have lost a good deal of weight already, 900 - 1000 Calories daily may really be what you need for maintenance. In that situation, and it's not uncommon, 1200 Cals would make a person gain weight. The "1200" Calories is a general rule of thumb: individually the situation may be different.

I agree that the hard fast 1200 cal rule doesn't apply to everyone, however if she only ate 900 calories and burns 1,000 that means she she negative 100 calories for the day so she isn't even eating enough to fuel her workout much less BMR activities like breathing. It is totally unsustainable and if continued over even a short period of time can be very dangerous. Not to mention the side effects that will occur with her weight loss.

I understand that people are very opposed to blanket rules, but to tell someone that it is okay to be that far under on calories, much less negative is doing them a grave disservice.

Perhaps you could have read my post a little better. It wasn't directed at her situation but a general comment. Also, generally, most people underestimate their caloric intake and overestimate caloric deficit because of exercise, and then wonder why they plateau. Also as a general comment. MFP offers a one size fits all approach, based on outdated ideas about nutrition. So the guidelines that the site delivers, I'm not sure about their value in specific circumstances. Then you're far better off with a nutritionist's advice than with a rule of thumb from the creators of this site and tool. Just my personal opinion, so take it as that, please.
