One of the most enlightening books I have ever read is The Secret Life of Fat by Sylvia Tara. She is a biochemist who has studied how fat is essential to our health and well-being as women. Our fat manufactures and stores hormones which help regulate how we store energy for living, child-bearing, and keeping healthy post-menopause.
Fat is an essential organ. Yes, I said organ because even though it is not a discreet well-contained organ, it nevertheless serves a essential role in the physical and chemical protection of the body. It makes many, many hormones: leptins and greylins, which control hunger and cravings, and hormones which allow women to become pregnant and carry children to term. And if there is not enough food or space, it limits pregnancies until food supplies return.
The Secret Life of Fat is available on Amazon Books as a paperback or audiobook. It was the best $8 I ever spent.
