F-Factor Diet The F in F-Factor stands for fiber. "The focus of this diet is to consume large amounts of fiber while still enjoying lean proteins and moderate amounts of healthy fats," explains Morgan. "Alcohol, an occasional sweet treat and dining out are also allowed." Founder Tanya Zuckerbrot's motto is, "Fiber and protein at every meal make losing weight no big deal."

Pros: Morgan is a fan of this diet because of its emphasis on fiber, which favors gut-friendly bacteria and has a positive ripple effect on overall health. "There's a focus on balance and a healthy relationship with food, which is KEY to long-term success. I believe this is a type of eating style that is sustainable over time." Fiber, the non-digestible part of a carbohydrate, decreases appetite by making you feel fuller after eating (it swells in the stomach) making it key for weight loss. Fiber also helps regulate blood sugar, which is why the sugar in fiber-rich berries, for example, will not affect your body the same way that sugar in processed candy bars will.

Con: The only con Morgan sees is that this eating style can be too flexible for someone that has serious health problems or someone with true food addiction that has to draw hard lines with sugar and alcohol. "This is where self-awareness becomes incredibly important to know what type of eating style you will thrive with," Morgan says.
