For a thing to grow, it must exist in the first place. Visceral fat exists before it grows, and it exists naturally, it serves a purpose a priori, therefore any risk associated with it is merely incidental, not causal.
Fat tissue growth is not a cause, it's an effect. That this effect is associated with disease does not suddenly turn this effect into a cause. Disease itself is an effect as well. Therefore there is an association between two effects.
So what's the cause? Some pathogen, some dietary factor, some injury, or a combination. For our purpose, the primary cause of fat tissue growth is dietary carbohydrates through their action on insulin. With fat tissue, it's a special case. Once it grows, it can remain larger permanently through a process called insulin-induced lipohypertrophy, just like any other tissue that grows through similar processes, i.e. bones, muscles, eyes, skin, etc. So fat tissue isn't really a special case after all.
You went low-carb, you fixed the primary cause. But low-carb can't fix this permanent growth, it's there to stay, there is no mechanism where fat tissue can be shrunk permanently by diet or by exercise. Unless we look at removing fat tissue physically like with liposuction or with a drug called Adipotide (prohibitin-targeting peptide 1, or PTP-1) which causes the blood vessels lining fat tissue to suicide, fat cells die off as a result, fat tissue shrinks permanently.
If carbs were the only cause, then you're good to go. If there was other causes, find them, fix them. The sequence is:
carbs -> insulin -> fat tissue accumulation. So the sequence is:
carbs -> fat tissue accumulation. But the sequence can also be:
drugs (or some pathogen, or injury, or inflammation from these) -> insulin -> fat tissue accumulation. Therefore the sequence is also:
drugs (or the other things) -> fat tissue accumulation. The sequence is always:
something -> insulin -> fat tissue accumulation.
Now that fat tissue has grown, has it become dangerous on its own? It's possible, but unlikely. Fat tissue on its own does not cause disease, unless we're talking about lots of fat, then the disease would be called something like "can't move cuz I got this huge weight pinning be down", which is actually possible, but that's not what we're talking about here. We're talking 1kg of fat tissue mass inside the abdomen cavity. There's probably 20kg of stuff in there, 1kg isn't gonna make much difference. But it's not 1kg, it's half that, cuz fat tissue grew, remember? It grew from whatever it was, to 1kg, so it probably was already 0.5kg, and it didn't make a difference then. So, in order for 1kg of visceral fat to become the culprit, we have to believe that only 0.5kg of it is the culprit, while the other 0.5kg just keeps doing its thing which has always been there for a genuine purpose.
The experts don't do this super simplified logic, they're not trained to look at things like that. For them, it's all about statistics. Well, There Ain't No Such Thing As A Free Statistics. It's all gotta be based on genuine facts, otherwise it's just an idea, belief, not real.
Let's look at facts. How do you feel since you went low-carb, since you lost all that weight? Make a list of things that changed. I did, my list is impressively long. The fact that we don't quantify these things with exact numbers is irrelevant, we can feel things and it's real, it's facts. I doubt we can feel the difference between 1kg of visceral fat and 0.5kg of visceral fat, so why all the fuss? Even if we could feel that difference, it wouldn't be that obvious, so why all the fuss? Granted, that fat was obviously much larger before, but we shrank it with low-carb, right down to the minimum possible it can be, after it had grown permanently a bit of course. Think about it, we don't visit the doc when nothing's wrong, unless we believe the doc can somehow divine the future, he can't, let's not fool ourselves. We are the ones who know when something's wrong, we can feel it, it's real, it's facts. Somehow, at some point in time, somebody convinced us that what we feel is an illusion, and the only thing that's real is lab numbers. Really?
Making a list is awesome. Somehow it makes these feelings more real, as if the feelings themselves weren't real enough. They are, there's just something magical about reading it on paper.
Am I an expert? Not in the least. I'm just some guy on the internet, and everything I say is BS.
