For anyone wondering, this is not an experiment, it's an epidemiological study. I've commented about it on HN before [1], but nutritional epidemiology is in its own league of shady science. If you didn't know, 80% of things you eat give you cancer [2]. That being said, sugar is bad. Main-lining sugar by drinking it in huge concentrations seems even worse! Edit: that being said, if you are doing nutritional epidemiolo…

Sugar is not bad. Just like meat or bacon is not bad. Why would sugar on its own be bad? Obviously it's the whole lifestyle and diet that is bad. There are cyclist that carb load by eatig raw sugar and have no metabolic issues like some of the overweight diabetics do when they drink their second gallon of sugary coca cola.

I ate more sugar than anyone I knew, and in 2011 I was diagnosed with type II diabetes.

I had no family history of diabetes, I was never overweight, and was always athletic.

Admittedly, this is a sample set of 1, but I remain convinced that my voracious appetite for sugar played into my diagnosis. I no longer eat sugar (with the exception of fruit).

What does "mito" have to do with anything lol. "nutritional epidemiology is shady science, but if you are doing it try my side project mito" can't argue with that.

It is really shady spamming from him, unrelated to anything.

As a 41 year old man getting remarried, I'm personally interested in the subject of serum testosterone. I have noticed a sharp decline the past couple years and I'm sure aging plus computer job plus covid is a noxious blend. General advice out there includes lower stress, lose weight, keep active, get sleep, weightlifting is good, cardio is good but maybe not too much, IF may be good. Scientific studies are good but…

A lot of people are starting to use TRT in older age. If it worries you this much maybe you should ask youe doctor.

Which can yield amazing results physiologically, including a markedly increased incidence of cancer :/

I am aware of TRT thanks. Do you have personal experience with it?

I don't since I'm pretty young, but a few people I follow do talk about it. Check out Greg Doucette on Youtube qho talks about it a lot. (Although I think there are better sources online and you should ask your doctor)

More dietary cholesterol. Raw egg yolks (easier to consume raw) in as large a quantity as you can handle.

Cholesterol/saturated fat will clog your penis arteries which is the leading cause of ED. (In fact ED is one of the first symptoms of heart disease, the No.1 killer.)

Nutrition Facts has a page about testosterone, I'd suggest you start there: https://nutritionfacts.org/2017/05/16/foods-that-affect-test...

The interesting point in this study and one they reference is that >... After adjusting for possible confounding variables, BMI was an independent risk factor for low testosterone level In other words, even adjusting for obesity, consuming sugar-sweetened beverages is a risk factor. There is other sugar -> low testosterone link, separate from sugar -> fat -> low testosterone with adjusted odds ratio 2.29.

It's also possible that sugar-sweetened beverages are a proxy for something else. You can't establish causation with studies like this.

As a type 1 diabetic for 20+ years, I feel like two large but underrated issues in the overall sugar conversation are (1) the functional aspect of fiber and (2) the rate of consumption and its effect on the body (e.g. drinking a SSB all at once).

The body just has trouble dealing with a large amount of both insulin and sugar at the same time. When we reduce fiber intake the issue compounds.

Simply spreading out your normal daily sugar consumption throughout the day (you know, chew your food slowly ;) would have huge benefits in terms of your body's ability to convert glucose efficiently (what's at the heart of the type 2 diabetes epidemic). Add fiber back into the equation would also help this immensely.

I say all this to say that we shouldn't ignore the machine like qualities of the body in the discussion. Think about your intake rate along with the overall consumption.

>> there are hunter-gatherer tribes living today that consume a significant amount of sugar (up to 60% of their calories) and don't have the same problems with obesity, diabetes, The reason they don't have those issues is they are constantly burning calories and in constant motion. H/G is not an easy life and those tribes (both men and women) put in a ton of manual labor. In college I remember one film where a tribe…

That supports my claim. If they burn off the calories then they wont get fat and therefore avoid metabolic issues. My whole point is that the bodyfat is causing the issues. If sugar was the root cause then we should be seeing diabetes, etc. in these hunter-gatherer tribes.

Yeah, I should've been more clear that I was supporting what you were saying and agree with your point.

Yeah, maybe I can help here as I faced the same stark realisation some years back. Generally speaking, higher testosterone levels are correlated with higher protein and fat intakes, mainly because cholesterol is used by the Leydig cells in your balls to produce testosterone. I am not saying you should start adding butter to your coffee or whatever other dumb things the keto people are saying, but going very low-fat a…

That is very insightful information! Thank you greatly.

I must ask, do you know if there is a relationship between engaging in cuckoldry and developing low testosterone levels?

It was a pastime that I knew nothing about until I started working at a Ruby shop about three years ago. Some of my coworkers were active cuckolds and they encouraged me and my wife to give it a try. We did and it was quite the thrill seeing her experience things that I could never get her to experience even though I did not ever consider myself to be an inadequate lover.

But as time went on and I was denied all intimate contact with my wife, I found my body starting to change. My testes shrank until I could feel them no longer. My doctor did not seem concerned, though, but my T levels showed a decline.

When I got a new job and we moved to a different city we stopped that pastime. My testes have gotten bigger again but I do not think that they are as big as they were in times past.

Do you have any insights?

Which sugar is bad? Is fructose as bad as glucose?

For testosterone, they’re looking a sugar sweetened beverages which would either be sucrose or glucose-fructose (HFCS), so it cannot be answered

Here’s a recent study that found that sucrose and fructose double liver fat production when compared to glucose. Both need more “processing” than glucose making them more expensive. My theory is that the body compensates for this by trying to increase fat stored. The study found that this happens even with moderate amounts of sugar.

>Ninety-four healthy young men took part in the study. Every day for a period of seven weeks, they consumed a drink sweetened with different types of sugar, while the control group did not. The drinks contained either fructose, glucose or sucrose (table sugar which is a combination of fructose and glucose). The researchers then used tracers (labeled substances that can be traced as they move through the body) to analyze the effect of sugary drinks on lipid metabolism.
