Charlie Martin, who is making good progress on his goal toward healthier lifestyle, notes that the focus on weight is misguided:

In the first 13 weeks I lost two inches on my neck and two inches around my waist. In the following four weeks, I’ve lost another 3 inches (a total of FIVE inches) around my waist.

Obviously, I like the Army’s numbers better, so let’s use them — according to the Army, I’ve lost 5 percentage points of my body fat over the last four weeks, with my weight remaining stable. (Other methods give me somwhere around 29 percent, which is the most common value from the Withing body impedance too.) My weight is around 273, and 5 percent of 273 is 14 pounds close enough.

To have lost that much body fat, and still gained roughly 2 pounds over that four weeks means I’ve exchanged some amount of body fat for muscle, while also being around 32,000 kcals in arrears for that whole four weeks.

I’d remind Charlie that a lot of linebackers weigh more than him. I don’t think they’re necessarily fat.
