The Wizardry of Science

The hormones— insulin , ghrelin , human growth hormone (HGH), cortisol , leptin , adrenaline , noradrenaline , and hormone-sensitive lipase (HSL)—play key roles in regulating energy balance, metabolism, and physiological responses to stress. Here's how they interact and balance each other: 1. Insulin Role: Insulin is secreted by the pancreas in response to elevated blood glucose levels, promoting the uptake of glucose into cells, particularly muscle and fat cells, for storage or energy use. Balance: Insulin lowers blood glucose levels and counteracts the effects of hormones that increase blood glucose, such as cortisol, adrenaline, and noradrenaline. It also inhibits hormone-sensitive lipase (HSL), reducing the breakdown of fat. 2. Ghrelin Role: Ghrelin, known as the "hunger hormone," is produced by the stomach and signals the brain to stimulate appetite, especially when the body is in a state of energy deficit. Balance: Ghrelin levels rise before meals and fall aft
