Net calories

in Health and Weight Loss
When I have a busy day at work I burn easily 4000+ calories in a whole day, MFP adjusts and tells me to eat like 3,200. I'm quite satisfied to eat 1,800 - 2,000 on these busy days but sometimes end up with negative net calories. What does this even mean? 5 ft 9 246 lbs.

    It means you are eating fewer calories than is recommended to maintain the nutritional profile that most women need.

    A few days of that here and there is not really an issue, especially given your stats, but it really is recommended that women eat no less than 1200 calories daily to maintain a minimally optimal nutritional balance.

    Are you adding your work as exercise or is this coming from a fitness tracker? Your work should be part of your activity level and if you're that active be sure your activity level reflects that.

    Do'nt believe the burn it gives for exercise on MFP, I always found they were overstated. Use an independant site such as https://www.bhf.org.uk/heart-health/preventing-heart.../exercise-calorie-calculator . You can 'un-link' your phone so it doesn't automatically deduct for steps.

    ^^This. If you are active at work, make sure your profile states that you are active so it doesn't add back those exercise calories. I'd only worry about it if you're losing way too fast (like 2-3 lbs a week). If you're not losing weight, than you may be eating too much because you may be eating back those extra exercise calories.

    I just looked at your profile. Are you new to MFP? Is your activity tracker new? I noticed with my fitbit that it took a few days to accurately total my calorie burn. PS, what do you do that causes you to burn 4000 calories a day? Just out of curiousity. :)

    If you have negative net calories, then you are using more energy than you are taking in. Even though you may be eating at least 1200 calories, you are burning more than that, so its like you are not eating calories at all.

    As others have said, the fitness trackers on the market today are at best questionable in their accuracy regarding energy (calories) burned, so perhaps it would be worth while to consider reducing the number you eat back.

    My phone is not linked, I USB my Garmin into my laptop and the end of everyday. MFP profile activity is set to active, I don't let MFP calculate calories for any workouts my Garmin HR does all that. While I eat back some fitness calories I have never got close to 3,000.

    Setting to "active" and then tracking all activity is double-counting some activity.

    So what do people using fitness trackers set their activity to? It was on sedentary but it was suggested I change it to active.

    Are you losing weight? Are you losing at a high rate of loss or less than 2lb a week?

    Monitor how much and how fast you are losing for a month or so, it's likely your tracker is overestimating as 4000 calories sounds a lot. If you are eating plenty (you say you are eating 1800-2000) getting in the nutrition and not overly fatigued or showing signs of body issues then you are probably ok and it's an over-estimation issue.

    I don't think she's tracking any activity separate - she said she just lets Garmin and MFP work it out.

    This is exactly the way I did it when I had a tracker connected. You actually get less calories added because MFP already assumes you're burning a larger number than if you set it to sedentary. When I had it as sedentary I got way too many calories added. OP is already getting a large number added if she changed it to sedentary she'd get even more added. I think OP is doing it correctly.

    No, not with synced activity. If you set yourself to active and then sync activity from a tracker you only begin to accrue more calories when you exceed the calories estimated for an active lifestyle.

    Setting it to active just means you begin at a higher baseline than someone who sets it lower. You get activity adjustments after a lot more activity.

    I am losing weight, not super fast I would say on average 1.5 a week as it does fluctuate with hormones and kittens. I have a physical job and then on workout days or long days with Tball coaching ect 4,000 burn is really not a lot for me.

    If you are tracking ALL your activity, you should set it to sedentary.

    4000 calories a day is a very large burn for most people. What is your job??

    Then I'd say as long as you're getting adequate nutrition you're fine. If you were dropping several pounds a week I'd be concerned.

    If you are don't maintain on 4000 calories a day, then you are not burning that much.

    I work as a grower in a greenhouse and then 60 min of HIIT or cardio. Lets just say activity hasn't been my problem. Tomorrow is weigh day so we shall see as I have had a busy week. If I have lost more than 2 or not as much as expected I will have reevaluate what I have been doing.
