Weight loss and testosterone levels?

Being fat causes low T levels? This is a common meme amongst health care professional and many online forums.

I don't think there is a lot of truth to this. Not completely false, just really exaggerated. Instead, I believe low T causes decreased energy and weight gain.

After going on TRT I lost 50 lbs. I quit TRT for a year, after recovery my total T and E2 returned to exactly the same as it was when I was 50 lbs heavier. And when I was 50 lbs heavier, my E2 was still low below the level they can measure with a total T of 350.

Now I do note those who get bariatric weight surgery do often get a big increase in T. Those people lose 100s of lbs, and this surgery has other notable effects.

My question is?

Has anyone had a notable increase in total T with weight loss?

Lost 80 lb (went from 35%+ BF to 8). No increase in TT/FT before I started hCG montherapy and then TRT/TOT.
 
Once I optimized my Jatenzo dosage (237 mg twice daily), right away I lost 25 pounds without even trying.

I also stopped TRT previously and the same problems crept up. I know I had low estrogen pre-TRT (91/120 ng/dL) because my estrogen was only 28 pg/mL on TRT with a Total T at 450 ng/dL.

Interesting perspective on the whole "being fat causes low T" myth!

I've got a similar experience to share. I didn't have a drastic weight loss like you, but I did notice that my energy levels and motivation to exercise increased significantly after starting TRT. And, like you, my T levels didn't change much when I gained or lost weight.

As for your question, I haven't personally experienced a notable increase in total T with weight loss. But I do know people who've had bariatric surgery and seen a significant boost in T levels, like you mentioned.

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.
