In this video, Dr. Berg talks about intermittent fasting, autophagy and your muscles. Autophagy is the state you can get into when you do intermittent fasting – where the body is recycling old damaged proteins. It gives the body a catabolic effect or a breakdown of something.

Benefits of Autophagy
• Anti-aging
• Longevity
• Better Immune System
• Decrease Inflammation

When you don’t want to lose muscle mass while doing intermittent fasting, add strength training as a part of your workout. Loading up muscle to recruit as many muscle fibers as you can.

1. Go heavy weight with lower amount of reps
2. Go moderate amount of weight to failure

Or you can do a combination of both. These two actions can create a hypertrophy effect on the muscle which can keep them bigger and prevent them from shrinking when you are doing intermittent fasting.

Intermittent fasting has emerged as a popular trend in recent years as it has been proven to benefit one’s health in countless ways, such as regulating blood sugar levels, reducing cholesterol levels, and contributing to weight loss. However, one of the most significant concerns associated with intermittent fasting is preventing muscle loss. Dr. Berg, a renowned health and wellness expert, has developed a comprehensive guide to help you avoid losing muscle when doing intermittent fasting.

The Benefits of Intermittent Fasting

Intermittent fasting has been proven to benefit human health in numerous ways, such as:

  • Regulating blood sugar levels: Intermittent fasting has been shown to lower blood sugar levels, leading to increased insulin sensitivity and lower chances of developing diabetes.
  • Reducing cholesterol levels: Studies have shown that intermittent fasting can lower bad cholesterol levels and increase good cholesterol levels.
  • Helping with weight management: Intermittent fasting results in weight loss by reducing calorie intake, increasing metabolism, and improving insulin sensitivity.

Understanding Muscle Loss When Doing Intermittent Fasting

Muscle loss is a common concern associated with intermittent fasting, which could lead to long-term weakness, fatigue, and decreased mobility. When the body goes into a calorie deficit, it breaks down the stored glycogen in the muscles to produce energy. The glycogen is then replenished through stored fat. However, the body may also break down muscle protein for energy under certain circumstances, leading to muscle loss. There are several possible reasons why muscle loss may occur when doing intermittent fasting:

  • Inadequate protein intake: Your body needs protein to build and repair muscle tissues, and if you don’t get enough protein in your diet, you’re likely to lose muscle.
  • Over-exercising: Doing too much exercise without proper nourishment can trigger muscle breakdown, especially when combined with a calorie deficit.
  • Insulin resistance: Insulin resistance caused by overeating can lead to muscle breakdown.
  • Aging: Muscle loss is a natural process that comes with aging, and when combined with calorie restriction, it may occur more rapidly.

Preventing Muscle Loss When Doing Intermittent Fasting

To prevent muscle loss when doing intermittent fasting, Dr. Berg suggests the following tips:

1. Increase protein intake

Protein is crucial for muscle gain and retention, so it’s essential to ensure that you’re getting enough protein in your diet. A diet rich in high-quality protein sources like eggs, fish, chicken breast, and grass-fed beef is ideal.

2. Engage in resistance training

Resistance training, like weightlifting or bodyweight exercises, helps build and maintain muscle mass. When combined with proper nourishment, resistance training can prevent muscle loss during intermittent fasting.

3. Eat frequent meals

Eating frequent meals can help prevent muscle breakdown. Instead of consuming two or three large meals, try splitting your meals into five or six smaller ones.

4. Avoid over-exercising

Over-exercising without proper nourishment can trigger muscle breakdown, especially when combined with a calorie deficit. Ensure that you’re doing the right kind of exercise and getting the appropriate nutrition to prevent muscle loss.


Intermittent fasting is a proven method of improving overall health, but preventing muscle loss is essential. By following Dr. Berg’s tips, you can prevent muscle loss and gain all the benefits of intermittent fasting while retaining your physical strength and mobility.
