Correct Me If I Am Wrong...

Monday, July 09, 2012

Basal Metabolic Rate (BMR) is the amount of daily calories it takes for someone to just exist, essential bodily functions only. It is based on gender, age, weight, and height. Generally, being taller and heavier increases this number, while age decreases it, and men normally have a higher number than women.

Does it make sense then that if my current BMR is 3679 and the BMR of my goal weight is 1966, if I consume at my goal weight BMR level, I should return to my goal weight, eventually?

So...

3679 - 1966 = 1713 daily calorie deficit
1713 * 7 = 11,991 weekly calorie deficit
11,991 / 3500 = 3.426 pounds lost per week

This assumes total sloth mode.

Sorry for all the math this late at night...lol.

Has anyone else tried figuring the numbers out like this for themselves?

How did it work out?

Was it accurate?

Thanks for the feedback!

    BMR is the number that you should NOT go below. That is the basic caloric range that your body needs to have your heart beat, to support blood flow.

It's what happens ABOVE that number that needs to be controlled and adjusted. I always go back to the "your body as a car" example to explain this concept.

If you turn on your car and just leave it parked, it burns gas (food). If you don't have enough gas (food) in the car (your body), the car will stall and stop working, causing damage to the engine and other parts. Your body will suffer damage if you don't have enough food to meet it's Basic Caloric needs.

If you are driving your car over mountain passes, it takes more gas than driving in the flat lands. If you are exercising, running, lifting weights etc, you need more food to maintain the baseline of your bodies functions.

Just as you need gas for your car, you need enough food for your body. Your BMR is exactly that, a Baseline, starting point. Except under a licensed physicians watch, you should not go under it.

    I know SP uses BMR to help calculate what our caloric input should be. When I was much heavier, I was shocked to see ranges approaching 3000 calories, which I believe was BMR plus the amount of exercise you chose (light, moderate, heavy). I thought the #'s were way too high, so I always ratcheted mine down. Unfortunately, this is when I measured none of my foods, so as an example, when I did takeout from one of our favorite Italian restaurants, what I thought was a 3 oz piece of chicken actually turns out to be 12 oz on average, and 1 cup of pasta was really 2!! So basically I was sabotaging my own efforts!!

For me, measuring my foods has been the key. It keeps me honest and of course is a heck of a lot more accurate than the old "eyeball" method. Plus I get the added benefit of multiple dinners out of one "order" (money saver!). It takes some practice and a food scale, but believe me it is worth the effort in the long run!

    Far be it from me to try to correct anyone. I'm old, fat, and out of shape too. But I'm getting better. Mostly because I'm changing things not so much based on what I can figure out, but because I'm doing stuff different from the stuff that got me in the shape I'm in.

If you figure out a way to change the "getting older" part of that, please let me know. The calender keeps changing on me. emoticon

    Your math is completely correct...unfortunately, bodies don't know math...or if they do, they don't care about it. I'm at a similar point, and eating in between my calorie ranges pretty much every day (and making sure they are good, whole food choices, not filling my calories with sodium and crap food)....and I'm lucky to lose 2 pounds in a week...with almost 15000 deficit per week (including excercise and diet). There are weeks where I will actually lose not even one ounce...which is beyond frustrating knowing the basic math behind it! I hope your body does math better than mine!

    BMR is a good number to know, but your mileage may vary. Calculations based on weight, gender,etc. are approximations. Your actual BMR is as individual as you are.

Your metabolism will change with what and how much you eat, as well as what you do when you're not being a total sloth, so while the numbers seem reasonable based on a simple calories in/ calories out model, it probably won't work like that.
