    Can intermittent fasting breakdown muscle? Is intermittent fasting safe?

  • #2
    Hi RachelThorpe,

    The question of whether intermittent fasting (IF) causes you to burn more muscle mass is a common worry for anyone who begins IF.
    The short answer is no, because your body aims to "conserve protein".

    When you begin fasting, your body initially draws its fuel from carbohydrate and stored glycogen sources. Later on, it switches to fat and ketones.
    There is research dating all the way back from the 1980s which showed that excretion of nitrogen (a proxy for muscle breakdown, this is measured in the urine) did not increase even with fasting for up to a few days even.
    There is also more recent clinical studies where researchers put subjects on alternate day fasting - the results actually showed no loss of lean mass/body composition stayed the same (Templeman et al, 2016. Intermittent fasting, energy balance and associated health outcomes in adults: study protocol for a randomised controlled trial.)

    As to whether IF is safe- this depends on the individual's background past medical history. For most healthy individuals with no past medical history, yes, IF is indeed safe. But if you have any concerns pertaining specifically to your own health and situation, then it is best to consult a doctor.

      Intermittent fasting is an effective method to lose weight because here you have to follow lifestyle rather than diet. It reduces the insulin levels of the body. There are different protocols are available to follow such 16/8 and 24-hour protocol. In 16/8 protocol it means you have to follow 16 hours of fast and 8 hours of having food. In 24 hour you have to skipped meals per day example- if you are eating food at 8 pm then again you can’t eat food until 8 pm of that day. And yes intermittent fasting is absolutely safe because it is considered as low carb diet.

        I agree with the previous comments. As a fitness trainer, I can say that it is safe and helps to throw off the whole. And yet, as said earlier, this is not a diet but a lifestyle. I always advise my clients to try different techniques for losing weight. But if you feel that you only get worse, try something else. In 4 cases out of 10 people have to change diets or exercise regimens - and this is quite normal. If you feel uncomfortable, try another low-carb diet and a few cross jump exercices with rope
        This will help you lose calories and strengthen your body.

          It is not necessarily impossible to gain muscle with intermittent fasting, but that may not be the easiest diet for gaining muscles. Intermittent fasting requires you to eat fewer calories and eat less frequently than a normal diet. Because of this, you may have trouble getting enough calories and protein to build muscle.

            Intermittent fasting probably does not cause more muscle loss than other weight loss diets. Nevertheless, adding exercise, especially weight training to your intermittent fasting program can help you maintain muscle. However, whether or not you exercise during fasting periods is up to you.

              It is true that intermittent fasting helps to lose fat but some worries that it may cause muscle loss also. When you lose weight, you are losing both fat and lean mass, especially when you are not exercising regularly. Some researchers believe that this fasting method can be more effective in maintaining lean mass and does not cause more muscle loss.
