Intermittent fasting: why women should fast differently than men – Thomas DeLauer
Wherever you look on the Internet, someone will tell you that fasting is terrible for women. They will tell you that your thyroid will be destroyed. They will tell you that your hormones will be completely out of control and you will never recover.
Well, it's not quite true. In this video, I want to give you the breakdown from A to Z of what happens to the female body during a fast, particularly during intermittent fasting. How often should a woman fast? What can you expect? What is happening to your hormones and what is happening to your reproductive system? In this video, I'm going to take it from A to Z of what happens, starting with starvation and appetite hormones, which leads to reproductive hormones and then to the thyroid. We are going to submerge, and men, this video is for you too, because it will also help to describe exactly what is happening in your body.
Okay, this is the thing. When it comes to hormones of starvation … we are talking about leptin, ghrelin, insulin, things so we should pay attention when it comes to hunger and satiety … women are much more sensitive to them. It's not bad, nothing happens to them. It is simply a protection mechanism. It is not the fact that the thyroid closes. It is the fact that the female body is recognizing that no food comes in, so they do not want to produce eggs. They do not want to be ovulating. It's natural. Why would a female body want to produce eggs to stimulate potential reproduction if they are not eating, if they are starving?
That's where all this starts. Everything has to do with leptin, ghrelin and insulin. But it goes much more than that. We are going to talk about what is happening with the brain and with the gonads now.
Let's talk about GNRH. GNRH is a particular thing secreted by the hypothalamus in both men and women, and has to do with what is called the hypothalamic-pituitary gonadal axis. I know many guys who are proud of the HPTA, thinking that it only has to do with testosterone and their male bodies. Oh no. That is not the case. The axis of the HPTA, all that process, are men and women. And that's how it works.
Your brain has an area called the hypothalamus. This hypothalamus ends up secreting something known as GNRH. This GNRH tells the pituitary gland to produce luteinizing hormone and the follicle-stimulating hormone. What these hormones end up doing is triggering the production of sperm and testosterone in men and producing ovulation and triggering progesterone and estrogen in women. They both do the same, only with a different end result. We still have the same catalyst, the same hormones.
Now what ends up happening is how women go through this process compared to men. Now that we know about GNRH and understand that the HPTA has to do with men and women, we can talk about the GNRH precursor, which is where the problem really begins, and that is something called kisspeptin. Where the problem with kisspeptin occurs is just that people do not know what is really happening. Most of the beef in the fasting community and most of the beef with women who fast in general, all have to do with kisspeptin.
