In Chapter 4, the author discusses our fat-burning friends. At one time or another, we all will face this desire to lose even a little bit of weight.
The hormones that directly stimulate metabolism are your thyroid, adrenaline, glucagon, and progesterone. The thyroid regulates our metabolism and organ function, and directly affect heart rate, cholesterol, body weight, energy, muscle contraction and relaxation, skin and hair texture, bowel function, fertility, menstrual regularity, memory, mood, and more. How could there possibly be more? If any of the above are abnormal, a simple blood test can determine thyroid levels. When it comes to adrenaline, I believe we all have experienced that surge of energy at some point. While we are feeling that surge of energy, our body is freeing up stored fats and sugars and also sparing metabolically active muscle protein. Glucagon basically converts carbs into energy and works directly opposite insulin. It tells the body to use stored fat and sugars for fuel whenever we exercise consume protein, or have a dip in blood sugar. Progesterone is produced by the ovaries before menopause and in small amounts after menopause by the adrenal glands. It supports the thyroid and can work magic when it is balanced with estrogen.
In the second part of the chapter, it discuses the hormones that stimulate fat loss. The hormones that fall into this category are DHEA, Testosterone, Growth Hormones, Serotonin, Melatonin, Dopamine, Acetylcholine, Gaba, Leptin, Vitamin D3. What a packed chapter. A lot of the imbalances in these hormones are similar such as, hair loss, irritability, lack of sex drive, inability to sleep well, fatigue, increased body fat, anxiety, depression, memory loss, and pain threshold.
There are a lot of hormones that make up who we are on a daily basis. Hormones are major culprits on how we handle our day to day routines. So, if anything doesn't feel right, why not check it out. The rest of the book continues to talk about hormones, but the conversation goes along with where your own particular hormones fall. For instance, our body composition says a lot about which hormones may need support and as individuals we'd have to see where we fit in in this text.
What I love about this book, is that it is giving the reader the power to help it's systems through behavior changes like sleep, relaxation techniques, exercise, and food choices, over medication. Being a vegan, I would not choose to follow most of the menu plans, but I can still apply the methods and science to a vegan diet.
