Fasting makes your cells gain energy from other sources that you could miss on your normal days.

During fasting, the internal system goes to survival mode and replaces the bad cells with the healthier ones. After few days of fasting, the lesser free radicals will be formed inside the body and your cells will get enough energy to fight off free radicals that cause stress.

All this procedure helps in maintaining chemical balance inside the body and your body would be able to resist stress.

  1. I’m wondering, in your opinion, what would healthy fasting look like in a diet or attempt to cleanse the body? Unless for a specific religious reason, I can’t see a good reason to limit your intake of fluids like water.

    • Hi Lauren,
      That was one of my concerns when I started reading about fasting. I thought that if you did not consume food that would mess with your metabolism and if you did not drink water, then how would you flush toxins from your body.

      There were a few articles on The National Institutes of Health’s site that covered a lot about fasting for weight loss and diets. One article mentioned:
      In healthy, normal weight, overweight, or obese adults, there is little evidence that intermittent fasting regimens are harmful physically or mentally (i.e., in terms of mood).
      It appears that almost any intermittent fasting regimen can result in some weight loss.

      Intermittent fasting can be safe if done correctly.

      Thank you for you comment,
