Intermittent fasting has been a topic of discussion in the health and wellness world for quite some time now. It involves cycles of eating and fasting, with several health benefits. Dr. Mark Matson is a renowned researcher in the field and has been researching intermittent fasting, caloric restriction, and brain science for decades. In a recent interview with Dr. Ken Berry, Dr. Matson sheds light on the dangers and benefits of intermittent fasting.
Dr. Matson emphasizes that intermittent fasting is not dangerous and can be a good thing to do. He mentions that short periods of fasting, such as compressing the daily eating window to six hours or fasting a couple of days a week and consuming only a single meal, do not pose any contraindications for people with metabolic syndrome or who are overweight.
Dr. Matson further emphasizes that the critical thing with intermittent fasting is to use up all the glucose in the liver. Glucose goes into the liver when you eat, and it is stored as glycogen. If you are not exercising, it takes 12 to 14 hours to deplete those carbohydrate stores, and then you switch to using fats and ketones derived from them. People who eat breakfast, lunch, and dinner and are not exercising may never experience this metabolic switching, leading to fat accumulation.
The benefits of intermittent fasting are numerous. It can reverse obesity, type 2 diabetes, fatty liver, hypertension, and metabolic syndrome and has shown the potential to benefit brain function, mental health and increase leptin sensitivity. People with obesity often have leptin resistance, so their brains do not respond to leptin. Intermittent fasting helps increase leptin and insulin sensitivity, making glucose removal from the blood more accessible.
When asked why the medical community and dietitians insist on people eating three meals a day with snacks in between, Dr. Matson explains that it had roots in history when the Agricultural Revolution started. The farmers needed enough energy to support their muscle system. It became a convenient way to eat breakfast, take a break, and have lunch. The medical community’s view is slanted towards a for-profit industry, with companies like Kellogg’s and Post investing heavily in making breakfast the most important meal of the day.
In conclusion, intermittent fasting is not dangerous and offers several benefits. People with metabolic syndrome, obesity, and type 2 diabetes stand to benefit from it. The ongoing trials on intermittent fasting and time-restricted feeding testify to its safety and efficacy. As Dr. Matson puts it, “Fasting is good for the brain, muscles, liver, blood vessels, and long-term health.”

Summary of Transcript:
Dr. Ken Berry interviews Dr. Mark Matson, a renowned researcher in brain science and intermittent fasting. They discuss the benefits and potential dangers of intermittent fasting, particularly for those with metabolic syndrome, obesity, and type 2 diabetes. They also discuss the history of the three-meals-a-day eating pattern and the influence of the for-profit industry on health recommendations. Intermittent fasting promotes insulin and leptin sensitivity and can improve metabolic health. There are over 150 ongoing clinical trials for intermittent fasting, indicating its safety and increasing popularity in research.
