The threadmill is using just some averages, they should measure your weight to tell your average BMI, but it is not. They just use some averages.

To get the best out of it, calculate your BMI at Baseter BMI calculator and then take your averages, then make some calculations using an exercise table http://www.nutristrategy.com/activitylist3.htm , do the maths and get your real value.

@ Steve M and Lance: I forgot to talk about net calories! Apologies. Not sure how many calories are in a piece of fecal matter (that’s an IgNobel Prize waiting to happen), but Steve is right about how to calculate net calories, which you can also use to calculate net carbs.

@ Dixie N: The 300 calories in the sandwich ARE kilocalories. As I said in the graf before the sandwich came in, food is always dealt with in kilocalories, even if they’re simply referred as calories. The smaller calorie, that which it takes to heat 1 gram of water, is generally used in chemistry and physics and not food.

@ Dixie N

Food calories are actually kilocalories, as the article states.

They basically call them calories to save money and space when printing I think

Thats pretty much the only fact I retained from 10th grade chemistry.

Im confused… how many calories are in your peanut butter and jelly sandwiches? If 1 calorie is needed to raise 1 gram of water 1 degree Celsius then wouldn’t you need 300,000 calories (300 kilocal) to heat 300 kilograms of water?

@Lance Yes fecal matter contains calories. Fiber contains calories and is counted in nutrition facts eventhough your body doesn’t use it. You can get your net calories by subtracting four times the grams of fiber from the calories listed on the label.

Alright, this is is something that has bugged me for a long time (I apologize in advance for the visuals): How can they accurately tell how many calories something has, really? Calories are (simplistically) energy; But not all the energy is used up. The last time I checked, fecal matter burned (the statute of limitations on my “burning dog poo, ding-dong ditch” prank ended about 20 years ago but, trust me, it burns). If so, doesn’t fecal matter itself have calories? Has anybody figured out how to deduct those calories so we have “net calories”. Wouldn’t it be different for every person (or even every day depending on the person)? If there is an answer, please let me know – I am oddly fixated on this issue (much to my wife’s chagrin).

One question I’ve always had when it comes to weight plateaus is – how is it possible to stay the exact same weight (down to the tenth of a pound) for several days at a time?
