The purported benefits of fruit fasting include:
Creating a calorie deficit
Weight loss
Appetite regulation and increased satiety
Increased intake of antioxidants
System flush
While these alleged benefits may make you want to try such a diet, we advise against it.
Yes, eating only fruits for a couple of days may increase the amount of antioxidants you’re eating, but fruits have no proteins and a large number of them have little or no fat content. Doing this eliminates some major food groups from your diet, which is not healthy.
Consuming only fruits may create a calorie deficit, but you’ll most likely be undereating, which is really not a good health or weight loss option. Finally, you don’t need to go the extra step to detoxify or flush your body of so-called toxins. Your body already has a system set up to naturally do this through the kidneys, liver, lungs, intestines, and skin.
Yes, eating well may help improve the function of these organs, but you don’t need to go on a whole separate diet for this. As long as you’re healthy, eating a healthy balanced diet will keep these organs in tip-top condition where they can easily get rid of any toxins.
