Body fat - how much difference does it make for T to E

If someone was 20% body fat and then went down to 10% would the amount of T converting E significantly be reduced?

I ask as I do appear to be converting a fair bit to estrogen but I do have about 20% - 25% body fat
 
It varies dramatically person to person. There is no "conversion factor" equation that allows you to plug in body fat % and get a conversion factor. Labs are the only way to know how your body responds.
 
Sad to say that I am fat. My body fat percentage is somewhere north of 28% My conversion from T to E2 thus far is one that is contrary to most things I read about the T to E2 conversion. So I don't think you can universally apply this rule to everyone.

Definitely true! I think unless extremely obese body fat will have a minor effect and genetics has the final say as many lean individuals struggle with high estrogen.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
