Burning Calories

I am a 20 year old woman. I weigh 182 pounds as of today and my goal is 120. I have a question about weight loss. I eat 1200 calories a day filled with protein, vegetables, fruit, whole grains, and lean meats. Then I burn about 2000 calories a day through exercise. How many pounds can I lose each week if I stick to this diet and exercise?

    You're netting a -800 calories a day? It would be a good idea for you to see your doctor and perhaps get with a dietician.

    I have spoken to my doctor and a personal trainer and they both agreed that with my current body weight I am able to handle this many calories a day. I just don't know how to calculate the pounds I will lose each week.

    Why are you asking us then?

    If you are eating 1200 cals and burning 2000 -- you are NETTING -800. Meaning you are exercising off MORE THAN you ate. Is what the other poster was saying. Are you netting 1200 after exercise...? Meaning -- eating back your exercise calories.

    Do you mean your netting at 1200 calories a day or only eatting 1200 calorie and burning over 2000 ?? if thats the case your not eatting enough you might lose weight in the first little bit doing this but your body can't keep this up

    Im on a 1200 a day life style change and heres what i do :) MFP has set my calories at 1200 a day I eat ALL of these then when i excise i eat All those calories back as well BUT! when i say excise i dont mean walking the 10 min walk from the car park to work as i did this before getting healthy didn't help me then so dont see how it will now :) i also dont count "cleaning" as excise or shopping as walking or things like that as i done all them before my life style change and well they didn't keep my skinny then so i dont see how they are going to keep me skinny now :)

    Things i do log is walking with the dog , Sprints up the sand dunes when at the beach with my family , etc things i do over and above a "normal" day and of cause every little bit of food/drink that hit my tummy! ...

    Ive had great loss in nearly 4 weeks ive now lost 5kgs (10Lbs) Im 25 year old women with 30Lbs to lose ! I really hope this helps :) but just remeber every body is dff and what works for one person might not work for the next :)

    You're not sapposed to net a nagative number and I dont know what you are doing for exercise but I doubt you are actually burning 2000 calories a day. MFP way has a deficit built into it, when you exercise MFP gives you calories to eat back because exercising will create a larger deficit. I would recomened getting an HRM to have a more accurate calories burn through exercise. Eat back your exercise calories if you are doing it the MFP way because if you dont it will create a very large deficit and too much of anything is not good, including too much of a deficit.

    Well I eat small meals every 2 hours and exercise three times a day (1 hour each time). I do cardio, weight training, and a little bit of yoga. The reason I burn so many calories is probably because I'm so overweight. I'm sure it will slow down the closer I get to my goal.

    Beat me to this question, 2000 calories is an amazing amount to burn off in a day.

    Why not just do it and see the results. We didn't put the Wgt on overnight. Be patient with yourself and let nature take its course. You want to make life style changes you can live with after you reach your goal.

    Thank you everyone for all the advice. I will definitely take everything you guys have said into account.

    Honey get yourself a HRM. I weight more then you and workout 2 hours a day. I am lucky if my HRM tells me I burned 800. Don't trust MFP exercise calculations they are very inflated. If anything cut MFP exercise calories in half that will get you close.

    You can lose lots and quickly. But doesn't your appetite go through the roof?

    Everytime I try this, my appetite is out of control, I can eat my family members ...

    2000 calories - you'd have to run a marathon in 4 hours. You do not burn that many calories no matter how heavy you are.

    Agreed! I weigh 170 and an hour of HIIT exercise only gets me about 600 calories at the most. And strength training doesn't burn anything close to that. Even when I weighed 260 pounds, I'm not sure I would have burned 2000 calories in three hours. Buy a HRM and get an accurate reading. Netting -800 calories per day is not sustainable over even a short period of time. Your body won't have the fuel to do those workouts.

    This website was made so that you eat back your exercise calories.

    As to answer your question, there's a rule in thermodynamics where a system can only burn as much as it gets. If you are giving it less then what it needs, it's going to start picking and choosing what is essential to run and if it should run optimally. What this means? Basically that you'll stall fast, since running things optimally burns more calories then not running them at all. For example, you're probably getting cold quicker then you use to (food has a thermic effect called TEF). There's a tipping point where a huge deficit just isn't beneficial. This is why anorexics tend to gain weight on little food. And you're putting yourself there with significant weight to lose, which means if you do this for an extended period of time and try to go back to eating normal, you're body is going to panic and want to put on as much weight as it can to save for later.

    I'm 5'1" 180lbs and netting -800 is NOT okay and no, your body isn't going to handle it well.

    Even at my heaviest - 245lbs - this would not have been acceptable.


    ETA: Trying to lose this way means that the weight you are losing isn't just fat, but muscle. Aside from that, you are going to be looking at some nasty side effects. I would do research and talk to a physician and a registered dietitian.

    Ask your trainer what the plan is when you get to goal weight. Do you plan to do 3 hours for the rest of your life? How much do they figure you'll eat then.

    I've done the massive amounts of exercise and low calorie intake (not as low as you). I really struggled after reaching goal

    With extra weight, you can afford a larger calorie deficit, however, yours is far too big.

    Once in a while burning way more calories than you eat is probably ok, BUT you probably won't be able to keep it up for long. Maybe try going at it just a little slower. Exercise every day, but not so much ( 3 hours is a lot for EVERY day) and try switching up the types of exercise day by day...Some days eat a more than the 1200 calories if you are feeling tired, etc. It can be really tempting to start out weight loss full throttle, but it's hard to keep that intensity up. Slow and steady wins the race... I lost my weight by sticking to about 1200-1400 cal (I'm 5'3" and 46) and didn't eat all my exercise calories back, BUT I did occasionally. You have to fuel your body to be able to work that hard. Good luck!

    Can you make your diary public so we can see what you eat and what you log for exercise? Do you mean you think you're burning 2000 calories in actual intentional exercise each day or that is your TDEE (total daily energy expenditure)? Also how do you measure your food, with a food scale? I cannot believe your trainer and dietician haven't been more hands on with expectations regarding this "plan". Good luck

    I weigh more than you, and don't burn 2000 calories a day in exercise, even doing 2 a days. Also, yoga doesn't burn much. I think your calorie burn numbers are off. Unless you mean your TDEE is 2000 calories, as that's a whole different thing.

    If you really are burning 2000 calories in exercise a ice and beyond TDEE, and only eating 1200, honestly that's dangerously close to eating disorder/anorexic behavior, and can have far reaching and catostrophic effects on you physically and psychologically.

    Welcome, ahopen.

    I would like to encourage you to stop exercising so much and eating so little. This is very dangerous for your body.

    Burning 2,000 calories in exercise is an awful lot. For example, based on my body weight, the other day when I ran 4 miles at 5.2 miles per hour, it was calculated I burned around 500 calories or thereabouts. In order for me to burn 2,000 in one day, I would have to run 16 miles, or do some other combination of workout.

    If I ate only 1210 calories, I would get sick. I might lose weight at first, but my body would soon plateau and I'd probably not lose a pound.

    When I had a trainer, he taught me how to eat right, eat enough, and exercise well. In fact, I was about 180 lbs at the time and i worked out three times a week and he had me on 1360 calories a day. I lost weight slowly.

    It's just that over the last few years I'd forgotten those good habits and gained some back. Luckily I have been remembering how to eat right and exercise and have lost 18 pounds.

    I wish you the best of luck. :smile:

    Assuming you are 5'4" (about average) and lead a sedentary life, you burn about 1985 base calories a day. That assumes that other than the 3 hours of exercise, you spend the rest of your time laying on the couch watching TV or sitting at a desk job. This number from the calculator at www.fat2fitradio.com/tools/BMR

    1985 base calories + 2000 exercise calories = 3985 TDEE (total daily expenditure) - 1200 calories eaten = 2785 daily deficit
    That equals 19,495 calories per week or 5.6 pounds per week (3500 per pound).
    That represents a whopping 3% of your body weight.

    I'm very surprised your doctor thinks that's healthy. When your doctor okayed the 1200 calorie plan, did you disclose to him/her that you also planned to burn 2000 calories a day in exercise? Or did you just say you planned to do "some" cardio, weights and yoga?

    Because, without the 2000 burned, your numbers look like this:

    1985 base calories burned - 1200 cals eaten = 785 daily deficit
    That equals 5495 per week or 1.5 pounds per week

    If your doctor was under the impression that you were going to do a typical level of exercise (for example 2 days of cardio burning 500-600 calories, 2 days of strength burning 200 cals, 2 days of yoga burning 100 calories, 1 rest day), you would burn another 1500-2000 calories a week. That would put your weekly weight loss in a healthier 2-2.5 pound range.

    Think 3% of body weight is a healthy weekly weight loss? Read this article:

    Please be careful eating that little and burning that much! :)
    If your body does handle it then yes, you most likely will lose a lot of weight. But your metabolism will be extremely slowed and you will find it difficult to maintain that weight loss without continuing to eat 1200 and burn 2000. I am currently doing reverse dieting to undo the damage I did to my metabolism doing a similar thing to what you are doing.
    Just be careful and do some research outside of mfp. :heart:

    Two things: (1) I think it is very unlikely that you are burning 2000 calories a day. If you are using the calorie burn that MFP gives you, you should probably cut it in half because it is WAY overinflated. Invest in a good heart rate monitor so you can accurately track how many calories you are actually burning. (2) When you do figure out how many calories you are burning through exercise, eat at least half of those calories back or even all of those calories back if you are hungry. Like other people have said, you didn't get overweight overnight so don't expect to lose weight overnight. If you still don't trust the advice on MFP, go see your doctor. I don't know any single doctor who would approve of eating 1200 calories and burning 2000 calories (although I think that's an inaccurate number) on a daily basis! Good luck with your weight loss journey!

    What are you doing to burn 2000 calories and how many hours does it take to burn 2000?

    ^^ This

    That sounds way too high. Where did you come up with this number?
