Hello all, I just wanted to let you all know about something called the calorie deficit that i've learned so much about in this past week....Now as everyone on here know, it takes a person to burn 3500 calories in order to lose 1 pound of fat.....Also many have wondered if they should be eating their exercise calories........What I have found out is this......sure you can eat your exercise calories, but you should have at least a total of a 500 calorie deficit everyday, this way you would lose one pound a week. How do you get that deficit you might add........you figure all the calories you burn, with the calories you consume.....the difference between the two should be 500 or more.......and there you have it.......I have recently got a new device that they use on the biggest loser called The body bugg, and I must say, i've been wearing it for a week, and i've lost 4 pounds in that time......its a great tool and puts everything in perspective..........just thought I would share this little bit with you as I know many are wondering about if they should be eating their exercise calories or not.............Hope this helps........have a great day!!!

    That doesn't make any sense to me. Are you talking about calories left from exercising should be 500 or more? WHAT number is supposed to be 500 or more?

    Nobody explains what a "deficit" is. What is it??

    Ok Arielle, here is the easiest way I can explain it............say you exercise and the total amount of calories you burn is 2400 in a day, and just say that the calories you eat equal 1900.......if you take the 2400 and subtract 1900 that leaves you with 500 calories, that is your calorie deficit, thats what you need everyday for a week in order to lose one pound..........the deficit is the difference between the amount of calories you burn and the amount of calories you take in......

    Are you talking about exercising away 2400 calories? Let's not forget the calories you burn by simply existing.

    Keep in mind when you sign up with MFP and put in your goal and activity level, and how much per week you want to lose, it already has that calorie deficit accounted for. Be careful...you may be giving yourself 1,000 calorie deficit.

    (If I tell MFP I want to lose 1 lb. per week, it subtracts 500 from what it would take to maintain my current weight, and that's the daily allowance.)

    All this means is that say you are suppose to consume 1400 calories a day then lets say you exercise and burn 300 calories so that equals 1700 calories that you can eat but if you only eat 1200 calories you will lose a a pound a week if you continue to do so.

    So what's the point of everyone saying eat your exercise calories then?? So...I'm going to burn 600 or so calories today but I'm only eating 1,300. Am I supposed to subtract from the calories burned? Because the number is bigger...this still doesn't make sense.

    Luckily, MFP actually does all that work for you. ie they have already subtracted your deficit depending on how much weight per week you nominated to lose. So, for example - my goal before exercise is 1200cal/day. Now my body should burn somewhere between 1500 and 2000cal/day (without exercise) so even if I don't exercise, if I stick to the goal MFP gives me then I should lose weight. If I exercise, it adds these calories which you can then eat and still have the original deficit that MFP had accounted for. Hope this helps you Arielle.

    The way I was explained this is:

    I use 2200 calories a day in my every day life and I am only allowed 1200 because I want to lose weight (2200-1000=1200). So 1200 is my goal number each day. However say I burn 300 calories at the gym, then my goal for that day is actually 1500, because I need the extra calories that I used at the gym. Otherwise I am not eating enough and my body can go into starvation mode.

    Some people don't eat their burned calories - they stick with their numbers, say 1200 and it doesn't matter if they burned 800 calories at the gym that day, they don't eat extra food....

    My suggestion would be to talk to your doctor and see what they think is best for your body with your medical history.

    Arielle,
    Forget about the way it's being worded.

    If you consume 1800 calories in one day, and in the same day you exercise for 45 minutes burning 400 calories, you have essentially only consumed 1400 calories for the day. 400 calories is the deficit and your body must make up for that by burning fat, thus the weight loss.

    The Original poster is simply saying that if you make sure to either eat 500 calories less than you need in one day (7 days = 3500 - she didn't go into the detail) OR to eat the number of calories you need but exercise to burn 500 calories, then you can expect to lose at least one pound every week.

    Of course this may not work for everyone, but it's a general guideline according to the original poster.

    :)

    Arielle - I think that is why some people say not to eat ALL your exercise calories. So you can little by little figure out what works for you. But with the number you provided below I think this might work for you.
    You are suppossed to eat 1300 calories per day
    You exercise an additional 600 calories per day
    That's a total of 1900 calories per day
    1900 - 500 = 1400 calories you should be able to eat per day to lose a lbs per week.

    I don't think anyone is disagreeing with this...the point is MFP agrees with this as well, and already puts the deficit in for you. So you may be making your deficit larger than you intended (and possibly larger than it should be). Bottom line: no math needed! MFP makes it easy. Put in your initial settings, log your exercise, then eat the amount of calories MFP says to (or at least close to it).

    Example.

    Your body burning calories by just being - 1500 calories
    You burn calories by exercising - 500 calories
    Total calories burned today 2000 calories

    Deficit of 500 cals to lose 1 lbs/week - 500 calories

    You can eat this... - 1500 calories

    You can adjust the numbers where needed. If you burn more exercising, you can eat more. You can create a larger deficit by eating the same and exercising more, or exercising the same and eating more.

    Just be aware that there is a "starvation mode" point. I would think this would be different for each person, but it seems the average rule of thumb seems to be to eat no less than 1200 calories a day.

    ETA - MFP calculates all this in the required calories. When you input your exercise you also change the calculations. So, if you just go by the numbers that MFP gives you - you will have the same outcome.

    Yes it is a general guideline, and I didn't put the 500 X 7 = 3500 because I assumed most people would be able to figure that out, since I did say that you would need 500 a day for a week...........hence 7 days in a week..........but I do hope this helps....and if you want to have more of a deficit then you would lose more in a week then just a pound......i'm happy I was able to clear things up for some of you

    1900 - 500 = 1400 calories you should be able to eat per day to lose a lbs.

    BUT...in this example, if you are supposed to eat 1300 calories a day according to MFP, the 500 has already been deducted. This means MFP calculated you need 1800 per day to stay where you are, assuming no exercise. So it gives you 1300 per day, with no exercise, to lose 1 lb. per week. So, in the example above:

    1800 to stay put - 500 to lose + 600 burned in exercise = 1900 you should eat to fuel your body for that exercise AND lose about 1 lb. per week. Obviously this is a guideline, but it makes perfect sense to me and frankly has worked beautifully for me.

    This is what I am saying as well. If MFP tells you to eat 1300cal/day then you are really burning about 1800cal/day but they want you to lose weight so they have subtracted the 500. So if you exercise 600cal then you should be able to actually eat 1900 because your total energy burnt for the day would really be 2400.

    My calories are set at 1200. For a minute I thought I could only eat 700 a day if I don't exercise. I'm glad I read the entire thread!:noway: :laugh:

    I understand it. When you set up your account you tell them what kind of life style you have, and how much you want to lose. To maintain, I need 2270 calories a day, and that is with a life style of exercising weekly and burning 1170 calories a week, through exercise. To lose 1.5lbs a week, still burning 1170 calories a week with exercise I need to only consume 1520 calories a day, which is a deficit of 750calories a day than maintaining. Which takes away 5250 calories a week which then equals 1.5lbs. Because a pound is 3500 calories. Which is why I choose not to eat my exercise calories, unless I have like 1000 calories burned, I will then try to eat some back, like 200-300.
