some people go on eating junk food & still dont gain weight, so is internal fat more dangerous or external one

Internal fat is the cause almost all cardiac related health problems. The thing is, that people who are visibly obese can store them on the body. Skinny persons can't, that is why it is more dangerous to them. External fat does have drawbacks, which is mainly the cause of insulin resistance, thus promoting more fat to be deposited on blood vessels. (Insulin not only moves glucose, also lipids from the blood to the body)

internal fat is more dangerous because the fat in the inside clogs all your organs and could really cause a desease..external is no worry its just physical
