The diet Dr. Jason Fung recommends is made up of two main takeaways: when to eat and how to eat.
Eating at the right time can help end the hormone resistant cycle that causes unhealthy weight gain. Intermittent fasting is the method of fasting from food for a period of time.
It may sound hard, but there are several different versions of intermittent fasting. You can fast for an entire day or just portions of the day. You can also choose to simply restrict calories a few times a week. You can customize fasting to best fit your lifestyle with meal timing around your schedule. The goal is to simply go for extended periods of time without eating.
In addition to fasting, Dr. Fung recommends avoiding foods that cause insulin resistance. He recommends cutting way back on added sugars, processed foods, and simple carbs. You should also increase your consumption of fats, fiber, and vinegar. Think of it as a low-carb, mid-protein diet full of healthy fats and fiber.
