As the above text suggests I want to learn all about the working of hormones in the body along with how they work during the menstrual cycle. I also want to learn about how hormones work with nutrition and exercising. Any recommendations?
You can find all of this is a good biochemistry textbook - I like Marks Medical Biochemistry, and you can find it online.
Unfortunately, biochemistry is painfully complex so if you want to learn how it works, it takes a lot of study, even if you have a science background.
The Khan Academy videos have a good reputation.
