Metabolic Rate Increases During Fasting
Fasting causes the metabolic rate to increase, as shown in numerous studies. When you fast, your body's insulin levels decrease, allowing it to utilize stored calories. Other hormones, such as sympathetic tone, cortisol, and growth hormone, also increase, prompting the body to pull out calories. This activation is similar to the response of a hungry wolf, which becomes more dangerous and active compared to a lion that has just eaten. Contrary to common belief, fasting does not decrease metabolic rate; instead, it leads to an increase in metabolic activity. This perspective encourages viewing food as an instruction for the body, understanding its impact on hormones and the body's responses.
