Summary: (31 y/o male) For the past three months, I have had a severe drop in the urge/ "want" to have sex or even masturbate. From 8-10/wk total to 2x/wk and I think that is just habit and to make my wife feel better. I have had no life changing events and don't feel any more stressed than normal.
The only thing drastic that has changed is my health, but in a completely good way. In the course of a month, I went from no exercise to 6x a week (3x at 20 minutes and 3x at 45minutes) and went from eating the worst foods/nutrition that some people could probably imagine, to eating fruits, vegetables, proteins, and even consistently taking a multivitamin daily for the first time in 20 years. The first two weeks of my healthy eating I ate a 2000calorie diet/daily and didnt weight myself until the end of those two weeks and ended up losing 10 pounds. I lost ~23 pounds in the first month and have been relatively stable since. I am now at the lower end of the "normal BMI" scale.
I subsided on more snacks (carbs/fat) than real food for the past 8 years and now with my body is getting minerals/vitamins in quantities (appropriate ones) it didn't know existed.
Is it possible that I shocked by body into some hormonal imbalance?
(* I am seeing a doctor in 5 days, but would appreciate other advice as well)
