Hi! Like the other RDs said, research shows it’s no better/worse than other weight loss diets. 

However, intermittent fasting teaches your patients to ignore their hunger/fullness cues, which sets them up for failure in the long run. 

The ONLY time I recommended it was for a patient who was doing it to manage GI symptoms and even then I’m still hesitant. 

Using IF as a tool as can slow metabolism because you are putting your body in starvation mode if they are not starting their eating window early enough. 

I’m open for more research to be sent my way but ultimately if we are teaching patients this, they will likely gain weight once they go off the diet and therefore is not sustainable.
