Yeah, last year I weighed 143 lbs and I am 5'10". I got really bad with a throat infection and lost nearly 20 lbs. I couldn't take in food solids for over a week. I thought I was going to die. According to that test, I was a normal weight at 20.5. LOL Normal weight my ass. No body fat, and I lost a lot of muscle. At 160ish, I am still very lean and have low body fat, yet I scored at 23.0. According to that thing I am closer to being overweight. Yeah, okay.. if only I can grab fat on me. For me, the muscle is weighing me down. Muscle weighs more than fat. Regardless, I could be 175 at 5'10" and still have low body fat, and according to this thing I would be overweight. Yup, 25.1. I have friends who weigh that and more, and are my height and have no guts or love handles.
So this doesn't go for everyone. This is definitely not an accurate tool IMO. Some people also have more denser bone structures than others, and because of it, weigh more, even though they appear lighter.
btw Pixletwin, going based on your last few pics you're chubby, but hardly obese.
