    You will probably have a hard time losing weight at those calorie amounts if you are active.

    ^^^^ Im with ya about not catabolizing lean muscle.. But medical studies have shown that if you are overweight/obese your body will use fat cells as the primary source of energy conversion to keep your body moving, and it will not use lean muscle until other options have been depleted.. Now for someone who is lean, low body fat percentage like yourself.. and hopefully soon me :).. Lean muscle will become a an option for the body much faster as a source of energy.. And def, that will suck...

    The OP is not obese, and she is severely under eating at 600-800 net calories.

    Yes, that is too low.

    Eat higher calorie, non "bulky" items if you aren't hungry...

    almonds, peanut butter, protein bars, Greek yogurt... just to name a few are a great way to use up those calories when you just don't feel like eating.

    Good luck!

    I wonder this as well, I eat 1,000 cals a day cuz I want to lose about 2lbs a week. but after exercise sometimes my net is as low as 400. Should I eat back until i am at net 1,000. Or just let it go. BTW most of the time at the end of the day and throughout the day I am not hungry and feel perfectly fine (health and energy wise)
    I have a sedentary job but I do a lot of random calisthenic workouts and videos throughout the day and I also do real workouts like elliptical and weight training

    You can feel fine and not hungry but be creating a very unhealthy environment for your body. Eat at least 1200 net calories.

    BMI is not the best calculation to use, but even with that, her BMI figures out to "slightly overweight", not obese.

    true... true.. actually BMI can be pretty annoying to follow sometimes...

    my 2 cents is still, "slightly overweight' means your body can use the stored fat as energy while on a calorie deficit.

    When y'all say eat back the calories from working out you mean eat back to what your goal originally was? example my calorie goal is 1000 so should I eat back until i net 1000 or should I eat back ALL the calories I burned?

    OK I have to defend the OP. For some people (like me) it's very difficult to lose weight unless you eat about 1,200 calories per day. This is the minimum amount of calories for a healthy weight loss, and the National Institute of Health backs this up. If you're netting a little below 1,200 because of exercise that's OK in my book. Now, 600 does seem really low, and I only do moderate circuit training for about 20 minutes a day, so I usually NET at least 1,000.

    For those of you with significant weight to lose, it makes sense to eat more than 1,200, but if you're on your last 10 or so pounds, good luck losing on more than 1,200!! :wink:

    Same for me...on last 5 pounds....often below 1200 net in week...but eat more at weekend.....

    Not an UNHEALTHY deficit, like she has been eating, that is stupid.

    Your calorie goal should be 1200 at least. This website doesn't advocate that you eat any less than that. If you chose 2 pounds per week, it will set you at 1200, not 1000. So where are you getting the 1000 from?

    So, MFP sets you at 1200. Then you exercise 300 calories, now your calorie goal is 1500 for today total. 1200 just to live on plus 300 for fuel for your workout.

    Just going off some advice a friend gave me. So you say eat the 1200 plus the burned cals from the workout.... so where is the deficit needed to lose weight?

    I'd love to read the science behind your statement.

    what's the point of doing 2 hours of cardio, just to eat the calories back? might as well sit at home watch tv and i guess eat less..

    The deficit you need is already built in with what MFP gave you. It sets you low so that you would lose weight doing no additional exercise. Then when you do exercise, you need to eat fuel for it.

    Here are some numbers to understand:

    BMR - basal metabolic rate. This is the number of calories they would feed you if you were in a coma to fuel your basic bodily functions, heartbeat, breathing, brain function, organs.

    TDEE - this is total daily energy expenditure, all the calories you need that is part of BMR for you to live, and what you need for all of the moving around you do all day. Also called "maintenance calories" because it is the number you would not gain or lose weight, it is the right balance of calories where you would stay the same weight.

    A healthy deficit is anywhere from 10-30% off of TDEE, but above BMR. (if you have a lot of weight to lose, like 100 pounds, you can do a 30% cut. But if you have like 10 pounds to lose a 10% cut is healthy)

    MFP calculates your TDEE when you do the BMR tool thing here and then it asks you how active you are. BUT then when you tell it 2 pounds a week you want to lose, it gives you 1,000 calories a day deficit, regardless of your BMR, to a minimum of 1,200 calories (because it is unhealthy to go lower).

    Unless you have a lot of weight to lose, you shouldn't choose 2 pounds a week because that is not healthy or sustainable for everyone.
