Should I eat back calories on 1,000 calorie diet?

You should not be on a 1000 calorie diet in the first place.

Put your stats into MFP. Consistently eat the number of calories it gives you. Eat your exercise calories.

How many calories did mfp allot to you when you put in your stats?

How much did you choose for weight loss per week?

What you are doing is very dangerous.

First of all, you shouldn't be eating less than 1200 calories in the first place. And then, yes, you are supposed to eat back exercise calories.

If you use MFP to set your calorie goal, exercise, but don't eat back any exercise calories, you are not using MFP the way it was designed.

Unlike other sites which use TDEE calculators, MFP uses the NEAT method (Non-Exercise Activity Thermogenesis), and as such this system is designed for exercise calories to be eaten back. However, many consider the burns given by MFP to be inflated for them and only eat a percentage, such as 50%, back. Others, however, are able to lose weight while eating 100% of their exercise calories.

This woman felt fine on low calories like yours...until her heart gave out and she almost died: https://community.myfitnesspal.com/en/discussion/10761904/under-1200-for-weight-loss/p1

At about your weight, 1200 calories plus exercise was a bad plan for me: I got weak and fatigued, even though I corrected as soon as I realized I was losing too fast. It took several weeks to recover normal strength and energy level. I was lucky: Much worse consequences are possible.

Eat what MFP says you'd need to eat to lose a pound a week, and eat back a reasonable estimate of your exercise calories. Monitor for 4-6 weeks. If you're losing too fast, eat a little more. If you're losing more slowly than targeted, on average, after that time period, and feel good, adjust to lose a little faster.

Try to think of the weight loss process as practice for maintaining your healthy goal weight permanently. Take your time, and make it a learning process. Please stay healthy!

Hi lovely, I’ve been where you are in terms of trying to restrict myself to a very low calories diet. It can make you feel empowered at first and of course your body will begin to lose weight because you’re at a calorie deficit. Everyone is telling you it can be dangerous, which is true, but I know when you’re desperate to lose the weight you will take risks and as long as you get results you will continue. HOWEVER having been where you are multiple times when I was younger I can tell you it is NOT sustainable, you’ll lose steam, become demotivated and the weight WILL come back on.

The only thing that worked for me properly and meant I kept the weight off for three years was doing it the MFP way, slowly and steadily. What you burn then is also more likely to be fat rather than water or muscle mass.

1200 calories is still extreme for some bodies but it is fine and you will lose weight healthily as long as you follow MFP and DO eat all of those 1200 calories and eat back any exercise calories.

Also if you are exercising/ doing cardio for an hour at your weight... you are burning way more than 200 calories. Double that and you’re probably at a closer estimate. So yay! More food AND sustainable, noticeable weight loss! What’s not to love?

Feel free to add me

You should really be eating more. Here's an interesting thread https://community.myfitnesspal.com/en/discussion/10761904/under-1200-for-weight-loss/
