Calories burned by THINKING

I realize this may, at first, look completely stupid. We ALL think, don't we?!

But I'm talking about the brain work that is required for long, extended, exhausting periods of really intense focus.

I have a sedentary job by nature, I sit in my office 90% of the day. So, my caloric needs are, naturally, computed accordingly. However, I have always found that my recommended daily caloric intake for just a one pound loss per week leaves me completely incapacitated. I literally cannot do my job after just a few days on that many calories (about 1350). Shoot, after just one day, I can't even make coherent thoughts or sentences by the end of my day. I literally feel like its dangerous for me to drive.

Is there ANYTHING out there that takes this into consideration? Honestly, I don't think my caloric needs are the same if I am sitting at home mindelessly watching TV for 9 hours or if I am at work sitting on my butt, but working incredibly hard mentally.

I can't follow MFP's recommendation for a 1 pound loss per week because of this. I need to "feed my brain", and though I know I can still lose weight by going over MFP's recommendation, I would like some concrete information on this.

    MFP is just a recommendation. If you feel this way eat more. The site is just using a mathmatical formula. If you need to eatr more to focus- DO IT!!

    :indifferent:

    I totally get you. I bet you burn even more calories if you are sarcastic - it takes a lot of brain power to think of something smart, funny and cutting to say.

    :wink:

    I realize that, I am just wondering if anyone knows of any way to apply this as a variable so that I can have a better idea of what I really burn a day.

    Eat more veggies.

    EDIT: let me elaborate. Your breaks down carbohydrates to use as energy. Thus, eat more veggies. It's healthy has lots of nutrients for your body and your brain. =)

    Don't know about calories, but the brain does use more oxygen than the whole rest of your body combined.

    At any rate, if you're feeling poorly on fewer calories you prob need to increase your intake just a smidge.

    perhaps u need to increase the quality of the calories you are feeding your brain... what kinds of things are you eating (or drinking) throughout the day??

    Set it to a half pound a week and make sure you are eating carbs.

    I think that perhaps you are really over thinking this (should I log that?).

    Of course the MFP calculator is not accurate for everyone. Try it out and see what happens on the scale. Then adjust your daily goal accordingly with the manual process this site allows. I would not use the defaults and then log your daily brainstorms in an attempt to adjust.

    I think I've found your answer...

    "According to Popular Science, your brain requires a tenth of a calorie per minute, just to stay alive." (http://chemistry.about.com/od/chemistryfaqs/f/caloriethinkfaq.htm)

    I just burned 0.05 calories looking that up. Hardly enough to work off my dinner, but respectable.

    There is a difference... brain doctors call that "intense" thinking "Being in the Zone." Your whole body is in tune with what your brain is focusing on. Your thought process is more clear, you can function better and you work faster and more efficiently. Dr. Amen (sp?) has a book out about training your brain... would be interesting to see if he has a total of calories burning while you are in the zone.

    1200 is such an arbitrary number :ohwell: Do you know what your BMR is? Your BMR or Basal Metabolic Rate is the amount of calories you need just to be alive (ex: if you were in a coma or bedridden, you would be fed this amount to stay alive). Since I'm pretty sure you aren't in a coma :wink: figure out your BMR and add your activity level, even if it's sedentary. Here is a good calculator to try http://scoobysworkshop.com/calorie-calculator/. There is no reason to starve and it's highly unsustainable anyway :flowerforyou:

    I run into the same problem, and fix the problem without increasing my calories.

    If I'm doing accounting or database work, I eat more carbs than I normally would.

    If I'm doing brainless stuff, and/or physical endeavors, I eat more protein than any other macro.

    If you're losing too much with your activity level set as it is, up your activity level.

    This is a MODEL - it assumes an average person at that activity level. We're all different. If you burn more, set your activity level higher.

    You can eat 10k worth of veggies and fruit and not gain, so that's a start. :laugh:

    I don't think you're going to get concrete information on how many calories your brain burns, because not enough is known about how the brain works yet. But a practical thing I would do in your position is to change your goal to 0.5 lb loss per week. Then MFP will up your calorie intake goals, and you'll be better able to focus at work. And if your brain really is burning all those calories, you may even find yourself losing more than 0.5 lb per week.

    While I don't think that office work burns a lot of calories, I hear what you are saying. I'm in grad school and spend my work days writing and thinking, so I get it. I find myself feeling sluggish and not very productive when I am following this program to a T. I also find that if I workout in the morning, I don't think as well for the rest of the day because I'm too drained.

    I think it's just that some bodies need a bit more to get by on and you need to eat more. Possible solutions would be to change your goals to aim to lose less than 1lb per week, enabling more calories per day. Or exercise more so that you can eat more and still lose. Or just eat more low calorie foods. It is possible to cram a ton of food into 1200-1300 calories, if you are willing to eat large quantities of vegetables everyday.

    I know exactly what you mean, sobriquet84. If I'm on a restricted calorie diet, I find myself wiped out if I have to do a task that requires intense concentration and thought. And it's definitely true that pound-for-pound, the brain requires greater power than anything else in the body.

    But the sources I've found say that the brain uses about the same whether or not you're thinking deep thoughts because most of your brain power goes to automatic functions anyway.

    I vaguely remember reading that on MFP *very* recently. A quick search revealed nothing though. =P
