The Science of Fasting:

Let's start with what Dr. Jason Fung has to say about fasting ?

Dr. Jason Fung is a nephrologist (a kidney specialist) and author who has written extensively about the role of fasting in the treatment of obesity and type 2 diabetes. Dr. Fung advocates for the use of fasting as a tool to help people lose weight and improve their overall health. He has written several books on the subject, including "The Obesity Code," "The Complete Guide to Fasting," and "The Diabetes Code."

According to Dr. Fung, fasting can help to reset the body's metabolism and improve insulin sensitivity, which can lead to weight loss and a reduction in the risk of type 2 diabetes. He also suggests that fasting may have other health benefits, such as reducing inflammation and improving brain function.

Dr. Fung recommends that people follow a type of fasting regimen called intermittent fasting, in which they eat during a specific window of time each day and fast for the rest of the time. He suggests that people start with a shorter fasting period (such as 12 hours) and gradually work up to longer periods (such as 16 or 18 hours) over time. It's important to note that fasting should be done in a safe and healthy way, and people should consult with their healthcare provider before starting a fasting regimen.

What are the common misconceptions and misbeliefs about fasting ?

Fasting is dangerous: While fasting can be safe when done in a healthy and controlled manner, it is important to consult with a healthcare provider before starting a fasting regimen, particularly if you have certain medical conditions.

Fasting will cause muscle loss: It is true that fasting can cause the body to break down some muscle tissue for energy, but this does not necessarily lead to significant muscle loss. In fact, some studies have found that intermittent fasting may help to preserve muscle mass, particularly when combined with resistance training.

Fasting is unhealthy: Fasting can be healthy when done in a controlled and balanced way. However, it is important to make sure you are getting all of the nutrients you need when you are not fasting, and to avoid overindulging when you do eat.

Fasting is not sustainable: While fasting may be challenging at first, many people find that it becomes easier over time. Fasting can also be customized to fit your lifestyle and goals, so it can be a sustainable way of eating for some people.

How does fasting work ?

During fasting, the body uses stored calories in the form of glycogen (a type of carbohydrate that is stored in the liver and muscles) and fat to provide energy. When the body does not have access to food, it begins to break down stored glycogen into glucose, which is then used for energy. Once the glycogen stores are depleted, the body begins to break down fat stores to produce energy. This process is known as ketosis, and it can lead to weight loss as the body uses stored fat for energy.

Here are a few tips that may help you get used to fasting:

Start slowly: If you are new to fasting, it may be helpful to start with shorter fasting periods (such as 12-14 hours) and gradually work your way up to longer periods over time.

Eat a healthy diet: Make sure to eat a well-balanced diet when you are not fasting. This will help to ensure that you are getting all of the nutrients you need.

Stay hydrated: Drink plenty of water during your fasting periods to help prevent dehydration.

Keep busy: Engage in activities that can distract you from feeling hungry, such as reading, exercising, or spending time with friends and family.

Expect some discomfort: It's normal to feel hungry or have cravings when you are first starting to fast. These feelings should subside over time as your body adjusts to the fasting schedule.

It's important to note that everyone is different and it may take some time to get used to fasting. If you are having difficulty adapting to fasting, it may be helpful to talk to a healthcare provider or a registered dietitian for guidance
