Chloe: You are the creator of the F-Factor diet which encourages people to eat a lot of fiber to help them feel full and lose weight. I also read on your site that fiber in one’s diet provides more energy, clearer skin, a flatter stomach, improved sleep and a healthier gut. Why don’t we hear more about the importance of fiber? How did you discover the value of fiber?

Tanya: I discovered the value fiber of fiber for weight management in my early work as a Registered Dietitian, when I acted as an extension of the medical team of clinical patients with conditions like cardiovascular disease and diabetes. My job was to create meal plans that would lower the cholesterol of cardiovascular patients or, in the case of the diabetics, help to manage their blood sugar levels. Both patient populations received versions of a high fiber diets because of fiber’s ability to lower cholesterol and manage blood sugar levels. The patients got healthier: cholesterol improved, sugars were better managed, and unexpectedly, across the board, all of these patients lost weight. The clients were living their lives normally, enjoying meals at their favorite restaurants, drinking alcohol, and getting healthier in the process. What I had not anticipated was that by prescribing so much fiber for the clinical benefits, these patients were simply feeling fuller throughout the day on fewer calories, which led to weight loss without hunger. Friends and colleagues of theirs noticed too and began to call in, requesting diets for themselves, but purely for the weight loss benefits, not to manage their sugars or cholesterol. This was the birth of the F-Factor Diet and the practice continued to grow from there.

The reason we don’t hear more about the importance of fiber is because it’s the nutrient most commonly associated with going to the bathroom–and historically that’s been more of a taboo topic. Fortunately, almost every day there is new research released speaking to the amazing health and wellness benefits of fiber. People are increasingly catching on, the nutrient formally associated with popping is now much more mainstream. 


Chloe: It seems like the rest of the world has finally started to realize the connection between what you eat and your health. Nutrition and functional medicine are finally coming to the forefront in healthcare. What would you recommend to young women who want to pursue the nutrition field? What courses, majors, skills and work experience would be beneficial to go into the nutrition field?

Tanya: There is nothing I love more than seeing young people interested in pursuing a career in nutrition. Many universities offer nutrition programs for those who ultimately want to go into the field. Before you even decide if you want to go down that route, I recommend taking classes like anatomy, chemistry and biology, as the programs are very science-heavy. Such classes will likely be required as well. If you’re unsure about whether you want to major in Nutrition, many hospitals and nutrition-focused private practices have internship programs where you can gain experience and learn more about what a career in nutrition is like. 



Chloe: Teenagers are notorious for their poor eating and lifestyle habits. The great thing about the F-Factor diet is that you have made it a lifestyle that allows you to go out to eat, travel, and not feel like you have to be punished like on a traditional diet. Can you give our readers some tips to think about such as a list of things to eat that are high in fiber, and conversely what foods to stay away from?

Tanya: One of the best features of F-Factor is that there are no absolutes, meaning if you are following F-Factor no one food is ever completely off limits, but rather could be included from time to time as a mindful indulgence. 

There are so many great foods out there that are packed with fiber. Fiber-rich foods are nutrient dense and typically are low in calories, so you can fill up without filling out. An added bonus, fiber boosts metabolism and your body burns more calories digesting fiber rich foods than foods that don’t contain fiber. Examples of high-fiber foods include: 

  • Fruits – Berries (raspberries, blueberries, blackberries, strawberries), apples, pears, kiwis
  • Vegetables – artichokes, hearts of palm, spinach, broccoli, cauliflower, carrots, collard greens, corn 
  • Beans – lentils, chickpeas, kidney beans, 
  • Nuts/ seeds – Chia seeds and flax seeds, almonds, pistachios 
  • Grains and cereals – bulgur, wheat, quinoa, barley, popcorn, wheat bran
  • F-Factor products – F-Factor Fiber/Protein Bars (20g fiber per bar), F-Factor 20/20 Fiber/Protein Powder (20g fiber per serving) 
  • Other products – High fiber cereals (All bran, Fiber One), Sukrin Fiber Syrup Gold, Enlightened Ice Cream Bars, GG Crackers



Chloe: You are known for making the GG cracker popular! How many should a person eat in a day? Is there any other product(s) that you would recommend for fiber? If not, what are the best toppings on GG crackers so that you don’t feel like you are eating cardboard ;)?

Tanya: For those following F-Factor, I recommend eating 4-8 GG crackers per day. One serving (4 GG crackers) have just 8g net carb, contain 80 calories, and 16g of fiber. GG crackers are a high-fiber replacement for bread. We recommend people pair their crackers with lean protein, to help keep them feeling fuller, longer—and to make eating them a more enjoyable meal. A few favorite ways my clients top their crackers include:  

  • F-Factor Pizzas – Low-fat cottage cheese or mozzarella cheese, tomato sauce and sprinkle with parmesan cheese and salt-free seasoning. Microwave for two minute or bake until melty. 
  • The NY bagel – Low fat cream cheese, smoked salmon, onion, and tomato
  • Huevos rancheros – scrambled egg whites, salsa, and low fat shredded Mexican cheese
  • PB&J – Almond or peanut butter and smashed fresh raspberries or strawberries
  • Deli sandwich – Turkey/Roast beef with Dijon mustard, lettuce and tomato (pickle on the side) 
  • Avocado toast – Mix avocado with 0% Greek yogurt for a yummy spread

While GG crackers are a great way for people living the F-Factor Way to meet their daily fiber needs of at least 35g fiber per day, they’re by no means the only high-fiber food I would recommend. I’m pleased to share I recently launched a line of high-fiber, high-protein products with F-Factor that have quickly become a valuable solution for people to meet their daily fiber needs. Included in this is the F-Factor 20/20 Fiber/Protein Powder and F-Factor Fiber/Protein Bars. 

For those unfamiliar with F-Factor’s 20/20 Fiber/Protein powder, it is a protein powder with 3 times more fiber than any other protein powder available to date. The “20/20” refers to the amount of fiber and protein in a serving—one serving (2 scoops) packs 20 grams of fat-fighting fiber to boost metabolism along with 20 grams of organic muscle-building protein, for just 150 calories. The powder is also gluten-free, soy-free, has no sugar added, is all natural, non-GMO, and Kosher. The powder comes in both chocolate and vanilla flavor, so it can be used to enhance the nutrient density of countless dishes; everything from waffles to pancakes, cakes and cookies, ice cream, and now the latest craze: muffins.  and so much more. It’s really a hero ingredient for anyone looking to manage their weight or improve their health. 

The F-Factor Fiber/Protein bars similarly contain 20g fiber and 20g protein per bar for 170-180 calories (depending on flavor). Delicious, healthy and convenient, these bars make the perfect afternoon snack. They’re also vegan, gluten-free, dairy-free, lactose-free, soy-free, all-natural, non-GMO, Kosher and free of artificial sweeteners. They are so good, I don’t go anywhere without one! 



Chloe: Can you suggest some great snack options whether for late afternoons or late night eating (of course not desirable, but sometimes necessary :))?

Tanya: Snacking isn’t optional on F-Factor—it’s mandatory. By eating a snack 2 hours before dinner, you won’t go into dinner ravenous and are able to make healthier decisions. Great #FFACTORAPPROVED snack ideas include: 

  • F-Factor Pizzas – 4 high-fiber GG crackers topped with low-fat cottage cheese or mozzarella cheese, tomato sauce and a sprinkle of parmesan cheese, microwave until melted. 4 “pizzas”: ~200 calories, 24g carbs and 16g fiber. 
  • 20/20 Muffins – Muffins made with 20/20 Fiber/Protein Powder are a great snack because they’re rather portable. I like to pair 3 muffins with a cup of tea for a snack. 
  • 20/20 Smoothie – 2 scoops F-Factor 20/20 Fiber/Protein Powder, with ice, unsweetened almond milk (or other liquid) and whatever other fruit, vegetables or ingredients you prefer. 
    • Nutrition varies based on ingredients included but at the very least 1 smoothie packs 20g fiber and 20g protein. 
  • F-Factor Fiber/Protein bars – Bars are among the easiest snacks that you can take with you on the go. They’re perfect to have on hand for when hunger strikes. F-Factor bars have 20g fiber, 20g protein per bar and are between 170-180 calories depending on flavor.
