Insufficient nourishment during puberty can lead to hypogonadism, amenorrhea, reduced insulin secretion, and unusually high cholesterol levels.

“And it is a dramatic shift for a young girl or boy that doesn't nourish themselves sufficiently. During that period, there are a number of downstream negative effects. I'll list out some of them, these are just a subset of the effects, hypogonadism. That's the lack of sperm production or healthy egg production. There is amenorrhea, which is the lack of menstrual cycling, okay? So, a failure to have a menstrual cycle. Reduced insulin secretion, insulin is this hormone that's released in order to help shuttle glucose into various tissues for energy utilization. That's down because energy levels are down so much.”
