5/05 - 141lb. 33.7 BMI
5/12 - 138lb. 33.4 BMI Stuck with Phase 1, but have added a glass of wine or piece of dark chocolate.
5/19 - 137.8lb. 34.0 BMI (':(')
Sad Very, Very sad! Started phase 2. added one piece of whole wheat bread or bowl of oatmeal, and one serving of fruit a day. No wine this week, but still had one piece of dark chocolate each day. I don't think I am losing anything again this week. |

Another weigh in day.
5/27 - 137lb (better than nothing again!) 32.7 BMI Considering I had a hand full of popcorn at the movie theater over the weekend - not so bad. Just wish I could loose more like 2-3lbs a week, instead of 1 or nothing. I am really happy with the BMI going down. Especailly from it going up last time. I hope someday to understand the BMI better. Anyone have any explainations? The BMI always shows lower on the fitday site than the one that I get when I weigh in on the comuterized scale (this is the one I go by) |

BMI is different than body fat percentage. BMI is simply a function of weight and height. you don't need a scale to calculate it, you can do it online too at sites like this one. http://www.cdc.gov/nccdphp/dnpa/bmi/adult_BMI/english_bmi_calculator/bmi_calculator.htm
It's not an overly useful indicator. It doesn't account for gender, bone structure differences or athletic builds for instance. It's just a very rough approximation of height/weight proportionality. For an overall health indicator, waist size and waist-to-hip ratios are better indicators. BMI is just easy to calculate, kind of like scale weight. Neither really tells you much.
Since your height doesn't usually change, your BMI will go up and down as your weight goes up and down since those are the only two things used to calculate the BMI value. If you changed the height on your scale to 60 inches from 61 inches and your weight didn't change, your BMI would go up. You will need to weigh less at 60 inches than at 61 inches to have the same BMI value.
And it's common to stall going into P2 for a couple weeks. You might be transitioning a bit quickly. Check the advice on transitioning sticky thread near the top of the P2 forum for more info on this process. good luck! |

| Thank you RedRox. I had been thinking the computerized scale was telling me BMI, but it is actually the body fat. This is the one I have been going by, even though I called it BMI. At least now, thanks to you, I understand the difference. Thanks again, I really appreciate it. |

| hehehe... OK, on to lesson #2! ;) Most scales use a bio-impedence method that measures the time it takes to pass an electrical current into one foot and see how long it takes to get to the second foot and also calculates the amount of water in your body and then uses this to get to your body fat percentage. The more hydrated you are, the lower your body fat. That's why the instructions usually say to weigh for weight in the morning and "weigh" for body fat percentage in the late afternoon before dinner. In the morning your water hydration percentage is typically much lower and your body fat percentage will be much higher, although your actual weight is typically at it's lowest point. In the late afternoon, your weight might be higher, but your body fat percentage will be often be lower. Basically, it's just a very highly variable number and looking at it like it means much in terms of your actual body fat percentage is not usually recommended. Following it in terms of long term trends is really about the best you can do with it. It's a "cute" indicator to help sale scales, but it's just not very accurate and subject to too many variables to infer too much meaning to the reading. If you really want to "reduce" your body fat, try weighing yourself in a low crouch. It really reduces the time it takes to get the signal from one foot to the other and you can reduce your body fat by 5% or more usually! ;) |

| Thanks for the great lessons :D I weigh in only once a week and try to make it Mondays (unless I am not working) and between 8-8:30am. I figure if the numbers keep going down and the clothes keep getting looser, I am doing ok. While it is great motivation to see the numbers going down, I don't put a lot of stock in them. I am really enjoying just being healthier! And loosing the weight to boot :) |
