The creator isn't a cardiologist. She's a registered dietitian, nutritionist and mother of three.

"I always tell my patients fiber and protein at every meal makes losing weight no big deal," Tanya Zuckerbrot said.

At a luncheon to benefit the Wellness Community, NBC6 health reporter and emcee for the night Diana Gonzalez introduced keynote speaker Zuckerbrot.

Zuckerbrot explained that most people fail when it comes to the "F" factor in foods: fiber.

"The American Dietetic Association recommends that Americans get between 25 and 30 grams (of fiber) a day," Zuckerbrot said. "The average American is only getting between nine and 11 grams a day. The F-Factor Diet recommends 35 grams of fiber a day, and while that might seem overwhelming, it's actually quite easy to do."

Zuckerbrot advised starting each day with high-fiber cereal.

"If you add some raspberries to that, or some strawberries, you can add another eight grams of fiber to your cereal," she said. "Your breakfast can easily have over 20 grams of fiber."

For a snack, Zuckerbrot said to try a handful of pistachios or crackers with high enough fiber to cancel the carbohydrates. But don't forget the fruits and vegetables, she said.

Zuckerbrot said it's not difficult to find high-fiber foods when shopping.

"Last year alone they introduced 670 high-fiber items to the marketplace," she said. "So, it's really never been easy to get fiber in really delicious forms."

She said the benefits are beyond weight loss.

"High-fiber diets also lower your cholesterol, they reduce your blood pressure, they reduce the risk factors for colon cancer and for breast cancer," she said.

Discovery Channel in Miami put the F-Factor diet to the test with its employees. After two months, the average weight loss was about 10.5 pounds.
