Landing on a “Goal Weight”

Math, science, and a little psychology informed my path this week. With a little help from my math genius grandson, I was able to figure out where I’m headed on my trek.

My health app, Health Mate, sometimes prompts me for a little chat. This week it was about fat and a healthy body fat percentage.

My body fat percentage today is still high. It’s 48%. That’s definitely down from where I was when I started at 51.5% (Yeesh. I remember saying I was carrying a whole ‘nuther person around with me.)

What I wanted to know this week was what would my weight be at a healthy fat body percentage? I had calculated my target goal another way based on all my measurements, but I wanted to see if I calculated what my weight “should” be with a 25 – 35% body fat.

I knew it was a relational fraction “solve for x” type of formula, but couldn’t remember how to do it.

I tried googling it, but came up empty. So, I asked my grandson, the math wizard.

He was able to help me right away.

I had to multiply my weight by the desired fat percentage and then divide that number by my current fat percentage.

Bottom line, the range for my target weight is between 129 (too low at my age) and 181 (the highest healthy fat percentage at 35%).

So, realistically, anything below 181 is good for my height and age, but the target I settled on is around 175.

I also thought it was interesting that “storage fat” protects your organs from shocks and trauma. I interpreted that to be psychological trauma, as well.

It was a good week. I’m at my lowest weight ever in the past 4 years. But, alas, 73 lbs left to go.
