MILWAUKEE -- When it comes to losing weight -- more dieters are turning to intermittent fasting. But does it work? Registered dietitian Lisa Grudzielanek with Your Tasty Life joins Real Milwaukee with the latest with what science says.

What is Intermittent Fasting?

Alternate day fasting: Also known as 'eat stop eat,' this plan involves fasting on 3-4 non-consecutive days per week. A 24-hour fasting phase is followed by a non-fasting day where you can eat as much as you`d like.

Modified Fasting: A 5:2 fasting plan means fasting on two non-consecutive days per week where you eat between 20-25% of your daily calorie needs. On non-fasting days you can eat normally.

Time-Restricted Fasting: you fast anywhere from 8-20 hours per day. You can eat freely during your non-fasting hours. The most common is limiting eating to an 8-hr window and fasting for 16 hours.
