> I didn't measure BMI beyond pinching my belly. It sounds like you kept track of your starting weight and ending weight. If you know your starting and ending height or can safely assume your starting and ending height are very close to your current height, you can calculate change in BMI. There's no need for a skin caliper measurement, as you seem to be implying.

I will have to look up BMI calcuations at some point (currently working), and add this data to my spreadsheet. Thanks, I didn't know this was possible.

  BMI is body mass in kg divided by the square of height in meters. The typically cited normal range is 18.5 kg/m^2 to 25 kg/m^2. Technically, you can use whatever units you want, but almost every chart uses units of kg/m^2, and if the units aren't explicit, they're quite probably using kg/m^2.

    I used an online conversion tool [0], and got these numbers. Starting BMI: 28.6 Ending BMI: 25.9 It says I am still overweight, even at my lowest weight. lol I am curious what these numbers mean to you? (I know I need to lose more weight, cause I can see it in the mirror...) [0] https://bmicalculator.mes.fm/ https://bmicalculator.mes.fm/

      A very lean bodybuilder could still have a high BMI. I don't have a reference offhand, but the US Army has a lot of data on military-service-aged men and their cardiovascular health risks. They found BMI isn't a great predictor of cardiovascular health. Some formula involving height and the circumference of the belly was a much better predictor of cardiovascular risks. A thin but tall westerner colleague in Japan told me that doctors in Japan are required to counsel anyone with a waist circumference over a certain limit about weight loss. There's no correction for height (or race), only sex. His doctor realized that my colleague isn't overweight, but still had to lecture him. BMI at least accounts for height, but can be similarly misleading.
