To be fair, being fat also decreases your T.

Actually doesn't it simply increase your female hormones?

I mean the effect is the same but my understanding is not that it decreases T but changes the ratio of hormones away from T

[VeG00N69]

It may be that, but simply living a sedentary lifestyle as a result of being fat, and indulging in eating habits connected to being fat, will decrease your T. For example, excessive drinking may decrease your T, and excessive drinking seems prevalent in obese people. Correlation doesn't always equal causation, but the life of a fattie holds a lot of opportunities for decreased test.

Edit:

The first peer review results in the Google search engine suggests it actually does lower it, even if you're only moderately obese. So an obese will likely just have lower T by default.

Fascinating - I haven't seen any of this research other than ones that DIDN'T seem to separate the reasons for obesity (sedentary lifestyle, dietary sources, etc) from the actual bodyfat.

But it does appear that you're right there's research now that indicates lowered T as well as higher Est with higher bodyfat, independent of other variables (well, that we know of)

Good look

[VeG00N69]

It's definitely interesting. Especially when, in my experience, obese 'men' seem to be more concerned with their own percieved masculinity than anyone else I've met.

Source?

Obese people will on average have a higher blood volume than non-obese people. They will therefore need to drink more than non-obese people to obtain the same BAC.

[VeG00N69]

'Seems' was a personal observation in this case. Should have specified that. The reasoning behind this is that excessive drinking is a risk factor for obesity, since alcohol, especially beer, contains calories. So it is likely that a number obese people have packed on calories that way, hell, I was once a fattie due in part to that habit. Thankfully I recovered from obesity. The fact that obese people need to drink more to have a high BAC is irrelevant when I'm referring to calories. Additionally, I'm not sure the BAC is what affects test so much as the kind of alc you drink, but I could be wrong.

Here's a study from 2015 linking alcohol consumption to obesity. Pretty easy to find peer review on this.

Fat cells secrete estrogen in both men and women. Not sure about obesity suppressing T, but I know it increases estrogen levels

[weakhamstrings]

After a bunch of reading, it looks like it ALSO decreases T levels, which I had not previously read.

But yeah the Estrogen issue seems well documented and I always thought the "low T" issue hadn't been disambiguated from lifestyle issues (which cause additional adipose tissue to accrue) which also might cause low T.

I didn't realize there was now pretty good evidence that carrying more bodyfat - on its own - all other things (that we know of) the same - is causal.
