Almost everyone knows having excess body fat is harmful to our health since it leads to obesity and a myriad of other conditions. But does having too little body fat (both subcutaneous and visceral) negatively impact our health as well?

Yes, it definately does. Too little fat can seriously obstruct the production of essential hormones. One type of hormone in particular, the sex steroïd hormones. Lacking them can seriously mess up a womans cycle, but also cause a variety of problems in men.

Fat is also very important in the uptake of vitamins, especially vit A, D, E and K. Important for your bones, skin, immune system and the prevention of blood clots.

Eating too little fat also shifts the balance from HDL (High density lipids) to LDL (low density lipids) and too much LDL can cause blood clots too, so weirdly eating too little fat is also bad for your heart and arteries.

You also have more hunger, a higher chance of depression, and even maybe an increased risk of getting cancer. But in this world not a lot of people have to worry about eating too little fat. Sometimes professional sporters can have these problems, for example woman professional runners or other sporters sometimes have these problems which first manifest as having a elongated, or a totally weird menstrual cycle.

Edit: spelling, also visceral as you said it can cause a problem, since fat sometimes protects certain organs, such as the kidneys.
