Worse than that. Subcutaneous fat (which is the one you can trim off with liposuction) usually expands relying more in cell expansion and not in hyperplasia. Visceral fat on the other hand, is way more likely to involve hyperplasia and you cannot use liposuction against this type of fat. This is also the fat that is very hormonally active and increases the risks of diabetes, heart disease, cancers, strokes.
Visceral fat is literally enclosing the intestines, major blood vessels, organs, etc. of the abdomen.
Nevertheless, it is possible to surgically remove this sheet of fat that's covering your organs, it's called an omentectomy. But it's a big surgery, and done only in case of cancer, not for weight loss. That is, in humans: https://pubmed.ncbi.nlm.nih.gov/29367725/
Right. A surgeon can't just stick a liposuction tube into the abdominal cavity and poke around. This would be major invasive surgery with a high risk of complications, far worse than leaving the adipose tissue in place.
