Light exercise is encouraged on fasting days to support metabolism from "summary" of The Fast Diet by Michael Mosley,Mimi Spencer
It is important to keep in mind that fasting days do not equate to complete inactivity. While food intake may be restricted, engaging in light exercise can actually be beneficial. This is because exercise has been shown to support metabolism, which is the body's process of converting food into energy. By incorporating light physical activity on fasting days, you can help maintain a healthy metabolic rate. When we fast, our bodies switch from using glucose as a primary energy source to burning stored fat. This transition can be facilitated by engaging in light exercise, such as walking or gentle yoga. Not only does physical activity help burn additional calories, but it also promotes the mobilization of fat stores for energy production. Furthermore, exercise can have a positive impact on insulin sensitivity, a key factor in regulating blood sugar levels. By improving insulin sensitivity through regular physical activity, you can enhance your body's ability to effectively utilize glucose and maintain stable energy levels. In addition to supporting metabolism, light exercise on fasting days can also help prevent muscle loss. When we fast, the body may turn to muscle tissue for energy if not enough protein is consumed. By engaging in activities that stimulate muscle maintenance, such as resistance training or bodyweight exercises, you can preserve lean muscle mass while promoting fat loss.- Incorporating light exercise on fasting days can be a valuable strategy for supporting metabolism, optimizing fat burning, and maintaining muscle mass. By combining dietary modifications with physical activity, you can enhance the benefits of intermittent fasting and promote overall health and well-being.
