NET CALORIES - I DONT UNDERSTAND!

    The problem is that MFP doesn't take into account exercise when setting calorie goals, and deficts.

    So, you and I could be the same weight, height, job etc, and MFP would give us both the same calorie goal for 1lb a week loss, by deducting 500 from our estimated daily calorie burn excluding exercise.

    Now, If I just went home every night and sat in front of the TV, and you did your 1000 calories of swimming, our daily energy output would be very different, and you wouldl be expending 1000 calories than me.


    But it does. If you set it to your normal daily activity (without exercise) when you start, and ADD any exercise that you do in addition every day, it will be far more accurate.

    My mom did the same thing in the 80s. She was netting 200 calories a day and after a couple months, she lost her hair. She has yo-yo diet every since. I set her up on this, she lost about 30 pounds and did great. But I had to talk her into eating.

    MFP works because you do not starve yourself. I would suggest researching your BMR and TDEE and it will help you understand. Good luck. Eat more.

    Well done to your mum for doing so great and losing 30 pounds (hopefully with a full head of hair too as the hair loss sounds scary!).

    My BMR is about 1485 and my TDEE was 1778 when i wasnt doing any exercise but is 2297 if i regularly do exercise at a moderate level. I dont really know much about eithewr of these things and what they mean, so I will definately do some research. Thank you :)

    Haven't read through the thread but I'm sure at least someone has explained the net calorie piece. What I will say is to be extra careful of your estimates for calorie burn. They sound quite high. It's doable, but there's a chance you could be overestimating (this is actually why some folks only eat back half or a quarter of their calories).

    Most of this advice is so wrong...

    Look at the big loosers diary, people who lost 50, 75, 125lbs. They don't eat the exerciser calories period. I eat some, but try to leave 800 to 1200 on the table.

    I'm following this guy .... joncowling1988.... regularly he exceeds his calories with exercise and he lost something like 125lbs.

    If your not hungry don't eat!

    I feel like I need something after exercise, so I eat it. But don't let anyone tell you you have to.

    Listen to your body.

    I know there are some different opinions flying around this post, but I just wanted to say thank you to everyone that has taken the time to reply and share their advise. I understand the net calories a little more now so that is great...and I also can see that using MFP has different benefits for each individual. I have taken on board the need to try and eat a little more when I am burning from exercise and will try to do this over the coming days. Ultimately though I do eat and have 3 good meals and do not allow myself to be hungry :)

    Thank you for the support

    With all do respect, I disagree. I have been here forever and never met anyone who did not lose while eating back your calories. When your metabolism is screwed up, it will not give you proper signals.

    It is dangerous to advise anyone that netting 286 is fine if you are not hungry.

    This.

    When you have been eating too little you stop feeling hungry. That doesn't mean you don't need food. Instead of just looking at people who have lost a ton of weight, maybe look at people who have lost weight and kept it off.

    OP IMO you should net your BMR. I'm not saying it isn't possible to lose the way you're doing it, but it isn't the healthy way to go about it, and you're a lot more likely to be successful long term if you don't crash diet (which is what netting under 300 calories is).

    I know others have said it but are you absolutely sure of your cal burns. Is your HRM set correctly? 1000+ cals in a day is a LOT. I'm 5ft2 and I'd have to walk or swim for 3 or 4 hours to get that burn.

    Listen to your body.

    Try EdDavenport, who has lost 300+ eating back his exercise calories.

    We can all find people/methods to support/justify our own methods. There are people who are sucessfull using every method, and people that have failed using them too.

    I find the majority of people I trust aren''t even following the MFP way, they are eating at TDEE less % defict, and no lower that their BMR.

    If the OP did that based on her estmated TDEE of 2300, she would eat 1500-1800 calories a day, every day.

    [/quote first thing, how on earth are you burning 1000 cals per day doing light activity, are you super obese at your height.? I dont mean this in a bad way, but i would have to spend about 4 hours working out to get to that level

    1000 is not what i burn every day.....but i swim for 1 hour and walk also with a HRM for a good hour

    im 5ft 1/2 inch and 166lb so for my height im pretty heavy

    Same here!
  • First of all, your calorie burn seems a bit too high. Especially if your resting rate is around 1400...

    Second, if you eat 1200 calories a day and have the energy to work out for an hour every day without any dizziness, headaches, muscle soreness then you are doing just fine.

    Myfitnesspal doesn't know your body as well as you do, and statistics apply to most people, not to all people. If you feel good, if these numbers are working for you, then don't over think it. It's not easy to find the perfect balance, but it seems like you've done it. If you're happy with the results and you feel healthy, why make changes that you don't feel you need?

    Im making an effort to get in exercise most days with a good walk and some swimming.....nothing too vigorous!.....and am burning between 500 - 1000 calories a day.

    I would think that is a SUPER high estimate for "nothing too vigorous", but I may be wrong. I can run 4 miles in 40 minutes and it is around 550 calories. That might be something to check.

    thank you, this makes sense. The calorie burn was yesterday and only given as an example as a comment when i logged my diary prompted me to add this post. The average is 1/2 - 1 hour walk and 1 hour swim and by burn is sometimes only 500 :)

    As you have just said, the deficiency is alreday baked into the allowance, so when she exercises she is actually making that defict much larger

    When it comes to deficts, bigger is not always better.

    I would think that is a SUPER high estimate for "nothing too vigorous", but I may be wrong. I can run 4 miles in 40 minutes and it is around 550 calories. That might be something to check.

    maybe im not giving myself enough credit for the effort then as 60 mins swim was 527, but this was using the figure from MFP. I walked to and from swimming which was 20 mins and a burn of 136 on my HRM. I also took a walk to the super market which 29 mins there and burn of 235 and 31 mins back and burn of 265. I turned my HRM off when in the supermarket as felt this would be park of my normal day as such.

    I think my figures for my burn are as accurate as I can get them :)

  • The problem is that MFP doesn't take into account exercise when setting calorie goals, and deficts.

    So, you and I could be the same weight, height, job etc, and MFP would give us both the same calorie goal for 1lb a week loss, by deducting 500 from our estimated daily calorie burn excluding exercise.

    Now, If I just went home every night and sat in front of the TV, and you did your 1000 calories of swimming, our daily energy output would be very different, and you wouldl be expending 1000 calories than me.

    to still get the same 500 calorie defict for 1lb per week you would need to eat 1000 calories more than me.

    This will also help - http://www.myfitnesspal.com/topics/show/818082-exercise-calories-again-wtf

    This was part of where i get so confused as i think id probably rather not exercise than eat more than i want :(

    Basically, if you exercise more, eat more. If you exercise less, eat less. Either way, your daily intake should be around 1200 every day so that your body doesnt go into starvation mode. I recommend exercising more and eating more to make up the difference (or some of the difference) because diet itself will only go so far, and when you exercise, you are boosting your metabolism which will help you burn the fat and actually lose fat as opposed to muscle. At the end of the day, make sure your caloric intake is around 1200.

    So say you eat 1400 on day 1. You burn 1000 through exercise. That leaves your net at 400 calories. To get back to around 1200, you need to eat 800 (400+800=1200).

    Say the next day, you eat 1300. You burn 500 through exercise. That leaves your net at 800 calories. To get back to around 1200, you need to eat 400 (800+400=1200).

    The first day represents a high exercise day. You need to eat back more calories to make up with difference.
    The second day represents a low exercise day. You don't need to eat back as much because not as much exercise was done.

    However, keep exercising because your metabolism will speed up and that increases the process by which you burn fat.

    Hope that helps!!

    I think you would be better off with a consistant daily calorie consumption goal. Its about what suits us psychologically as well.
    So forget logging in exercise at all.
    Carry on with your healthy activity. Truefully change your settings to moderately active and eat the calorie allowance given!

    That's a good article and intresting, but I quote this:

    "I’d also note that the combination of big caloric deficits and large amounts of activity clearly isn’t detrimental to everyone. Some folks can get away with it but, for many, it tends to backfire more than anything else."

    My advise is still........ Listen to your body.

    But, your body is NOT going to give you good signals if you are starving it. If you are fueling it properly, than this would be good advise.

    I do not get why anyone would want to eat less, when you can lose weight and properly fuel your body without starving it and killing your muscle mass in the process.

Please do not feel you can not give me your help and opinion, as giving it me led me to writing this post and get all this advise. Please keep supporting me and giving me tips etc as it is just want I need xxx

    The way I look at it, is its like driving a car. You have 1200 cal a day to use and if you do exercise you are gaining more calories but burning calories and you need to fuel them otherwise you are running on empty.
    I have found that when you put the exercise into MFP, the exercise calories can be too high. So I always say, eat your 1200 when exercising along with water and part of your calories you gain from exercise. Its all about eating the right things. And also eat after exercise as your metabolism is still working.
    Hope that makes sense.
    Good luck

    Thank you!!

    Ok, you really should only cut 250 cal's from diet, and another 250 from exercise. At the end of the week, that would equal 3,500 cal's, and 3,500 cal,'s = 1lb of fat. MFP tells you to cut 500 cal's from diet only. It is up to you to burn the 250 from exercise. SO...you should try to eat back atleast some of the calories you burn. Make sure that your calorie burning estimate is as accurate as possible. As was mentioned earlier, MFP doesn't have very good calorie burn estimates. You can look at other sources online, to help, if you need to.
