When a friend told her about intermittent fasting (IF), Jennifer perked up.

I enthusiastically recommended IF, yet during a subsequent consultation he complained he was actuallygainingweight.

But as Jennifer and Jon prove, no diet works for everyone.

And the details on how to do it correctly can be easily misunderstood.

Certain peopleincluding pregnant women and those with eating disordersshouldnottry IF.

And even when IFdoeswork for a patient, I always discuss these potential pitfalls and how to remedy them.

People with the following issues should reconsider:

1.

Studies show non-celiac gluten sensitivities, for instance, cancreate3gut and brain problems.

For patients like Jennifer, those issues had been there all along, but IF simply exacerbated them.

Life comes riddled with stress and anxiety, and fasting can amp up those emotions.

For some patients, those feelings arise from the idea that theyshouldbe eating rather than actual hunger.

Occasionally a patient doing IF will complain about feeling “wired” before bed.

Increasing protein usually helps with this.

Avoiding refined carbohydrates and focusing on complex carbohydrates (like sweet potatoes) at dinnertime can also help.
