KUTV - Intermittent Fasting

Intermittent fasting is become more trendy. Joy Musselman, Registered Dietitian Nutritionist at Intermountain McKay-Dee Hospital, stopped by to talk about the pros and cons of this eating style.

What is Intermittent Fasting?

Intermittent Fasting is a method of eating less for regular, short, defined periods of time. Its intermittent style differentiates it from general calorie restriction eating plans. Intermittent Fasting can present in different forms, most commonly as follows:

  • Alternate Day Fasting – days of fasting alternating with days of unrestricted food intake.
  • Modified Fasting – consuming only about 25% of normal calorie needs on “fasting” days.
  • Time Restricted Fasting – fasting for a consecutive number of hours followed by set hours of unrestricted eating during a single 24-hour timeframe.
  • Water is typically allowed during periods of fasting.
Pros vs. Cons?The health benefits of intermittent fasting are still being studied but may include modest weight loss, improved glucose control, improved cardiovascular health, and increased longevity amongst others.

Those who engage in an intermittent fasting style should be conscientious of the need to continue to consume high-quality, nutrient-dense foods during non-fasting periods. Additional intermittent fasting may not be recommended for some people including children, those that are pregnant or nursing, and those that experience hypoglycemia.
