A Q for Swanso...

I was reading your post "The definite guide to fatloss and abs" and I found this:
"Calorie Deficit for Fat Loss

This is from Lyle McDonald who is leading fat loss guru in the US. To find out how many calories you need to drop for fat loss and to maintain your current muscle mass, simply multiply your total fat mass in pounds by 31 and subtract that from you maintenance calorie total.

Weight - 158pds
Body Fat in Pounds - 17 Pounds
Maintenance Calorie Total - 2300 calories
Calorie Deficit - 31 x 17 = 539 "

Well, I checked this morning on weightwatchers scale that I weigh 127.6 lbs , 25.6% body fat, 54.5% H2O.

so that would mean that I have 32.7 lbs of fat. 32.7 x 31 = 1012.6 -->
and I think maintenance Calorie total is 2200...
soooo... I should eat arnd 1187 cals a day???

this past week, I just increased caloric intake to 1800.
I'm a bit confused.
Could you clarify this for me?
Thanks

btw.. I dono if it helps, but

Last week i was 128 and 27.6% body fat

today i was 127.2 and 25.6% body fat

I don't kno if it is all inacccurate, but the measurements are from the same scale.

I don't know...

It does measure body fat (I dont remember exactly, but something I read in the manual book long ago) by sending something, like a signal, through body... b/c it travels faster through fat faster than muscle, it gets the amount and calculates it.

something like that.

I also have weight watchers scales and they measure bmi as you create a profile and put in your height, age and activity level.

I have to say though that regarding they are pretty inaccurate. For the past year has been around 24% with those but when i joined new gym and have it measured properly with the calipers, it is actually around 21%.

this was written a while ago and i wouldnlt really use that anymore, ecspecially for someone just starting out

your improvements will come simply from eating the right foods overall, eating them in the correct protions then timing your foods correctly

no counting, no meausreing and no silly calculators

Nazzisoroush: What the scale does is send an electrical current through your body and measure the impedance it faces as it goes along. Different body tissues will conduct the current better, allowing for more or less impedance. In theory this will help measure the amount of body fat you have. However, these scales are generally inaccurate and can have different measurements based on a variety of factors, such as hydration.

Amatlack: All BMI is is a ratio of your height and weight, which is why it's such a poor standard (on the personal level) for fitness. This website has the formulas for it: http://www.whathealth.com/bmi/formula.html

I have seen those types of scales before, and IMO they are crap if your feet are wet / dry it changes the amounts drastically. I got on the scale it told me I was 216 @ 21% body fat. I just had a caliper test done the week before and it was 17%
