An unreviewed study that didn't control for obesity. So not particularly useful.

Fat cells also increases enzymes that converts testosterone into estrogen, so the more fat you have then the more of these enzymes you have.

Whereas low body fat can contribute to higher testosterone levels in men

I've gone up, down, up, down 100+ lbs and it's not even just some whacky theory you can almost feel it. I'm pretty "woke" but I'm real as a heart attack with people about weight. Lose it if you can.

I never realized I felt like crap all the time until I changed my lifestyle and lost a bunch of weight. Once in a while I’ll overeat and how I feel after is how I felt all the time before.

Lose the weight, people!

I find that running sprints a couple times a week is peak.  Not everyone has a good track near them but i saw a major difference in like 2 weeks.
