Do you need iron to gain weight?

Like if you are low on ferritin (8.8) could it make it difficult for you to gain weight since iron is needed for growth? This is what my doctor told me. My regular iron levels, hematocrit, and all that is normal. It's just extremely low ferritin.

I'll go ahead and say yeah, you need your iron both inside and out. Eat it. Lift it.
