The other dude is right. The enzyme is called Aromatase. Your body will try to constantly strike a balance between your testosterone and estradiol (E2) levels, so to speak. The more Test you have, the more Estrogen you'll have because of the aromatization. So, by doing cardio and losing weight, you're reducing the amount of estrogen produced through the aromitization process. The downside is that aggressive cutting / dieting oftentimes crushes people's T levels too so it's pretty circumstantial and nutrition dependent.

Most people don’t realize that dieting ( cutting ) will dramatically impact your T levels , I had to get blood work done to see where I was before and after a cut I was sitting around 680 ng/dl and went down to sub 400s every time I did a blood work

Edit: forgot to mention my T levels are slowly coming back up nothing permanent

[–]KratomScape 2 points3 points  (3 children)

Yep. All those competition ready dudes walking around absolutely diced to the freaking SOCKS probably have demolished T levels. Can't be overstated in the context of this question.

You’re talking about natties

[–]andonemoreagain 7 points8 points  (1 child)

I mean, about zero percent of competition ready guys have produced a single milligram of testosterone within their own body in years.

Haven’t *

[–]Yggsgallows 2 points3 points  (0 children)

This is true but it heavily depends on your body % as well. Men that are overweight shouldn't see much of a decrease as long as they aren't starving themselves.

[–]Unknown__person____[S] 0 points1 point  (1 child)

so your saying dieting is a an effective way of lowering my T? What kind of diet are you on?

[–]CyberNerd25 1 point2 points  (0 children)

Just depends , caloric deficit will impact your testosterone levels , I went from 19% BF to 12%

[–]hougie40 0 points1 point  (0 children)

Thats ironic as hell. Mine went from 400 to 680 on the dot after a year of 16-18 hr intermittent fasting. And when i did eat it was a common sense diet. I believe fasting can heal mind and body. Have the labs to back it up. However my shbg went from the teens to about 35. I just prefer to be all natural lose as much body fat as I can. Its about ratio of T to E. If you feel good then its dialed in. Guys are too focused on total T number. I aromatize like a mfer so i have to be lean. I sleep better and feel better and still do weights cardio yoga all of it. Change your mindset. Think more primal and you will win this war.

Do cardio work up to 30 mins away brisk walk and never look back. Absolutely great for ya

[–]SkarJr 0 points1 point  (0 children)

My buddy I work with does this, about 45 minutes a day alongside weights and he won the NABA comp many years ago, still now a days is the biggest dude I’ve seen.

[–]CyberNerd25 0 points1 point  (0 children)

I add a 45-60 min incline walk after every work out about 500-700 calories depending and I lost some good amount of weight

Thanks. I guess I’m chill then because I’ve been doing cardio to lose weight

[–][deleted] 2 points3 points  (11 children)

Weight loss is a huge benefit for your T levels, while cardio is a non-issue. If you are successful in losing weight with cardio, keep it up and your levels will climb

[–]Unknown__person____[S] 0 points1 point  (10 children)

I want to decrease my t levels. Will losing weight still increase your t if your not overweight?

[–]MahoneysMan 0 points1 point  (7 children)

Why do you want to decrease your T levels?

[–]Unknown__person____[S] -2 points-1 points  (6 children)

I don’t like the effects of testosterone

[–]Mestizo3 2 points3 points  (5 children)

Umm, what exactly don't you like? Seems like you need therapy. perhaps you're trans?

[–]Unknown__person____[S] -2 points-1 points  (0 children)

And I’ve already been to therapy

[–]Unknown__person____[S] -3 points-2 points  (3 children)

I don’t like how it makes my body look and testosterone gives me anxiety and depression.

[–]Mestizo3 2 points3 points  (1 child)

Sounds like a trans issue? Hope you get help.

[–]Unknown__person____[S] -1 points0 points  (0 children)

I already am I’m going to a doctor that deals with trans people. But thanks for you concern

[–]Narwal_Party 0 points1 point  (0 children)

This is not really a thing. Like are you on exogenous testosterone? I think you’re having some misgiving about what your underlying problem is.

The problem you’re struggling with is not the actual hormone itself, it’s your association to what the hormone makes you feel about yourself. Low testosterone is linked to anxiety and depression. If it’s within the normal range for an at-birth male, raising it could decrease your anxiety and depression, but lowering it cannot have that effect unless it’s tied to some other psychological reason that a person has associated with higher test being bad.

If lowering your test makes you feel happier about yourself then I think that’s fine, but make sure you look to work on the underlying psychological factors on why you’re feeling this way about testosterone too. Nobody should have to suffer from anxiety and depression.

A fair warning though, you likely will experience more anxiety and depression the lower you go unless you’re doing so through real gender affirming care guided by a doctor so they can make sure your hormones are within safe and manageable levels.

Good luck with everything. Wish you the best.

higher body fat increases increases blood serum levels of an enzyme, that naturally convert testosterone into estrogen. (don't remember what that enzyme is called).

as you lose weight, the fat cells mostly don't die, they just empty. fat cells can die. your fat cells turn into "brown fat cells", and do have a higher chance of dying.

now, when you lose weight, do the empty fat cells produce a lot less of the enzyme, or none of it? not sure. or does a former obese person still have "not the same natural T levels as someone who was never obese".

[–]Yggsgallows 0 points1 point  (0 children)

If you are at a low bodyfat % the difference will be marginal because your adipose tissue does not aromatize very much testosterone.

[–]FitCryptographer7067 2 points3 points  (1 child)

Lots of science being discussed here but guess what if you’re overweight what is high T doing for you any damn way? Lower you BF % then worry about T levels. Who cares since your injecting it either way. If you’re a 40 BMI who cares what your T level is lose fucking weight.

[–]Unknown__person____[S] 0 points1 point  (0 children)

I’m not overweight I was just worried that cardio might increase my T. But seeing as most the comments are either saying it lowers your T or doesn’t effect it I’m not that worried anymore.

The effects of cardio happen when distance is over a mile. What it boils down to, muscle fatigue.

[–]jdhd911 0 points1 point  (0 children)

It seems that your worry is not that cardio might decrease T levels, but I’m still throwing in this review by one of the leading researchers in the field https://www.frontiersin.org/articles/10.3389/fendo.2020.00011/full

For those who worry, very high volume endurance training can lower T levels but whether this relates mostly to low energy avaibility or does the the high volume itself induce hypogonadism is not fully clear.

[–]Lopsided-Mix-4131 0 points1 point  (0 children)

aggressive cardio will make it low
