Why F-Factor Works

F-Factor has 20 years of experience in helping people lose weight while living their best lives.

F-Factor educates you on how to eat a high fiber + lean protein diet to lose weight while feeling full.
Forget everything you think you know about diets. Seriously, F-that noise.

When you follow the F-Factor lifestyle of eating more fiber + protein, you can still dine out, eat carbs, and drink alcohol. (Because that wine isn't going to drink itself.)

Tanya Zuckerbrot, MS, RD, has been a global leader in the health and wellness industry for 20 years. As the creator of the F-Factor Diet, the most liberating and sustainable approach to weight loss and optimal health, Tanya has helped thousands lose weight while continuing to live their best lives.

The F-Factor Diet evolved from Tanya’s early work as a Registered Dietitian in helping people live healthier lives. She discovered that by prescribing a high-fiber diet, they not only felt better but lost weight while feeling full and fueled.

Tanya is the author of two bestselling weight loss books: The F-Factor Diet: Discover the Secret to Permanent Weight Loss (2006, G.P Putnam & Sons), and The Miracle Carb Diet: Make Calories and Fat Disappear the F-Factor Way – with Fiber! (2012, Hyperion).
