Or at least are profoundly misleading.
Nope I'm going to go with useless. You remember me mentioning I could get the percentage to jump by as much as 7% by flexing certain muscles? Or perhaps 5% by drinking 16 oz of water and then waiting 15 minutes?
Anyway here is my Weight loss chart:
Note the steady (cheat days excepted) downward progression?
Here is my fat loss chart, as measured by my scale:
So... I have lost 20 lbs, increased my muscle mass through exercise and you are saying my BF% has gone up?
I don't think so.
Eagle eyed readers may note that my current weight and BF% are shown here, something I have avoided mentioning, You may feel free to ignore it. I didn't initially mention my starting weight, because frankly it's embarrassing. People never believe me when I told them how much I weigh(ed) and apparently I carried it well.
However, as the weight comes off I feel more self confident, and less sensitive to the subject. I still don't intend to trumpet my weight until I meet my three month goal. Then I might post before and after pictures.
Or your reward for for me reaching it is not to do so. :P
