So i just bought one of those taylor weight scales from Wal-Mart that measures body weight, body water % and body fat. My question is I have been weighing myself every day. This is what i got Body Fat % 09/05- 13.0 09/06-14.0 09/07 12.0 09/08- 12.0 09/09- 10.0 09/11- 13.0 My question, is this scale accurate? How can my body fat % differ 4% in only 6 days? How can my weight jump up and down between 5 lbs? I weight myslef in the same clothes ( boxers) every night so it isny my clothes. Any ideas?
