While some purists argue that any calories break a fast, a cup of bone broth contains only 30-50 calories, leading many to adopt it for its nutritional benefits during fasting. The ideal daily quantity depends heavily on your specific fasting goals and the type of fast you are undertaking.

Studies suggest that after 72 hours of fasting, the body begins a coordinated, multi-organ transformation that can affect thousands of proteins, essentially rewiring your biology. This deep physiological shift is a core part of what happens to your body when you fast for 6 days.

According to research on medically supervised fasting, the body undergoes a profound metabolic switch from using glucose for fuel to burning fat and producing ketones within just a few days of starting a fast. Here’s a detailed look at what happens to the body when you fast for 21 days.

After approximately 24-48 hours of fasting, the liver's stored glycogen is typically exhausted, triggering a profound metabolic switch to sustain the body’s energy needs during a period of prolonged starvation. This metabolic adaptation forces the liver to take on new and demanding functions, with significant consequences for both its own health and the body's overall energy balance.

Many people use bone broth fasting as a gentle way to reset their digestive system, with common guided fasts typically lasting one to three days. This approach provides essential nutrients and electrolytes, making it a more manageable and nourishing alternative to water-only fasts for many individuals.

Studies indicate that the body preferentially burns fat for fuel during prolonged periods without food, rather than indiscriminately breaking down muscle tissue. This metabolic switch to ketosis is the primary mechanism that prevents significant muscle loss on an extended fast, but the process is more nuanced than simple fat-burning.

According to the Cleveland Clinic, refeeding syndrome is a potential, and serious, complication when reintroducing food after a prolonged fast. This guide explains how to properly break an extended fast to minimize risks and ensure a smooth, gentle transition back to eating.

The human body is remarkably adaptable, undergoing significant metabolic shifts during prolonged fasting periods, such as a 72-hour fast. As the body switches from glucose to ketone bodies for fuel, the digestive system slows down, making the reintroduction of food a critical step that requires caution.

After a 3-day fast, the body's digestive system has been at rest, with enzyme production significantly reduced. The best thing to eat after a 3 day fast is not a large meal, but small portions of easily digestible, hydrating foods to ease your system back into action. This gentle reintroduction is key to avoiding an upset stomach and maximizing the health benefits of your fast.

While a cup of bone broth contains around 40-50 calories and technically breaks a fast, it offers a gentle reintroduction of nutrients. Discover exactly how much bone broth should I drink to break fast and the correct way to do it for optimal digestive health.
