Hormones have a direct effect on the composition of the human body, particularly muscle vs. adipose tissue. Energy levels, strength, sex drive and performance are also controlled by hormones, along with the aging process and general health. What you eat has a direct effect on your hormone levels. I am going to focus on the basics of human growth hormone and how you can get the most out of it from your diet. Hormones 101 Human Growth Hormone (HGH or GH) and testosterone are the two primary anabolic hormones. This means that when the levels of these hormones increase, muscular size and strength will also increase. Because they are also lipolytic, they mobilize body fat for use as fuel, leading to a reduction in overall body-fat. Another hormone, trilodothyronine T3 ( thyroid hormone) also has anabolic and lypolitic properties.
