    it's when you're eating less than you're supposed to. less than your goal or less than what it would take you to maintain your weight. something like that. aren't you glad the first person to answer your question is a super tired insomniacal SAHM mom?

    It means you burn more than you consume. Such as you are suppose to eat 1200 calories and you eat 1199.

    Or it means you are to eat 1200 calories and you burn 700 doing Zumba class so you are now below 1200 calories because you subtract the 700 calories from the 1200 calories.

    Or it means you are to eat 1200 calories and you burn 700 in Zumba and you eat an additional 600 bc Zumba made you hungry and you need to end the day at around 1200 calories, then you can safely do that and still be at a deficit.

    Loll, So its eating less than I should? Or burning less than I eat? whatttttt? is there a way to calculate like exactly everything? Like I know I can add up the calories I eat no prob, and the calories I burn at the gym, but what about the things I do the rest of the day? Like the calories the body burns natually?

    It's when you're eating less calories than you need to maintain your current weight.

    When you set up your account it asks your activity level. That is so MFP can determine how many calories you need each day. MFP also figures in a calorie deficit based on how much you tell it you want to lose. Then it gives you your exercise calories back so that you can eat those and still remain at a deficit.

    Calculate your TDEE (total daily energy expenditure) and then just subtract 500 calories from it for a pound a week loss.

    ???

    Your body requires a certain number of calories to survive every day. On top of that, you burn calories every day with everything you do from brushing your teeth to walking to your car, even sitting at a desk. Plus some people exercise on top of that. All of these calories are your TDEE, your total daily energy expenditure. If you eat this number, you will neither gain or lose weight. If you eat over that number you will gain weight. If you eat under that number, you are at a deficit, you are burning more calories than you take in. This is when you lose weight.
    There are a number of reasons why many choose to maintain a modest deficit , 10-20% less than their TDEE is recommended. So if your TDEE is 2000, you would eat 1600 calories to maintain a 20% deficit.

    You do not need to burn off every calorie you eat with exercise.

    Its like you need a certain amount of calories a day to maintain your current body weight.

    so if you want to DECREASE that amount you weigh, then you need to create a calorie deficit (as in below the amount needed to maintain), you'll see this referenced as 'maintenance calories'

    so a calorie deficit is when your calories consumed are less than your calories needed to maintain current body weight

    So there are ways of determining your basic calorie needs, and then a healthy deficit is roughly 20% less than your maintenance, or *a deficit of 20%*

    I'm new to these terms and I'm still learning, but this is where I'm at.

    There are a bunch of calculators to determine these very important numbers in regards to your very own body and how you want to change it @ http://www.fat2fitradio.com/tools/bmr/

    did that make sense? did i say the same things twice?

    Yes, but I would have your 'deficit' as 500 calories not 1,000 with the amount you have to lose. One lb a week approximates 3,500 calories = 500 calories a week. So, this would mean you eat to about 1,900 calories. If you do not see the expected results after about 4 weeks (to take account of water weight due to our cycles) then tweak up or down. The calculators are just estimates and so you need to tweak to your personal situation.

    Okay So I've figured it out. My tdee is around 2400, so I need to have less than that. For the last week ive been trying to stay eating around 1200-1400, and going to to the gym ontop of that. I havn't even lost a pound in the last 7 days that ive been eating that, and working out. What am I do wrong?

    Yes.

    Too little then. The deficit would be well over 1000 and realistically, unless you're over 230lbs, that's a lot more than you need. 2lbs a week is tough on the body if you're under 170 lbs.

    Don't forget to eat back at least 1/2 of your exercise calories.

    did you weight all of your food?

    And weight loss isn't linear so don't expect the scale to go down every day. And take measurements/pics for a more complete picture.

    If she is using the TDEE method she should not be eating them back.

    When did you start at the gym? It is not unusual to see little or no change in the scale at first. When we first start working out, or increase intensity, our muscles basically retain water (has to do with glycogen stores). This can mask losses in fat. Scale weight is not always an accurate indicator of fat loss.

    Make sure you are logging and measuring accurately and give it a few weeks.

    Weight loss is not linear and can be masked by water weight. If you start exercising you can store gylcogen/water in your muscles. It is often up to 4lb or more.

    Also, make sure your are really accurate about weighing and logging your food as Chris mentioned above.

    Calculate your TDEE (total daily energy expenditure) and then just subtract 500 calories from it for a pound a week loss.

    Never mind. I found the answer by scrolling up.
