You can try out the app (including our Intermittent Fasting missions) for free right here:What Are the Negative Effects of intermittent fasting? In my own experimentation with Intermittent Fasting since 2014, I have found very few negative side effects with Intermittent Fasting. The quick answer is: “yes, Intermittent Fasting can affect men and women differently.”Anecdotally, we have many women in our online coaching program that swear by Intermittent Fasting, while others have had adverse effects. Give intermittent fasting a shot, track your results, and see how your body/blood work changes as a result of Intermittent Fasting and decide if it’s right for you. The Intermittent Fasting Adventure within Nerd Fitness Journey was specifically designed for a beginner who is interested in experimenting with fasting.
