How do we get visceral fat? Why do some men (and women) have solid fat stomachs that are still large instead of 'jiggly'?

I am in a Personal training course and my teacher was having trouble with this question. What causes the two different types of fats in the body? And what problems does it cause?

Visceral fat is much more prone to leaking out triglycerides, and because it is in such close proximity to organs, this can result in fat buildup in the liver.  Triglycerides in the liver lead directly to insulin resistance, which will continue to compound the problem.  Metabolic syndrome is now thought to be largely driven by incomplete storage of triglycerides by adipocytes.

Somewhat tangentially, this is why liposuction is absolutely worthless-all they do there is remove subQ fat, which increases the burden on visceral fat to store TG.  Many patients who undergo liposuction actually have poorer metabolic parameters afterwards.
