What You'll Learn

Eat at least 35g of fibre per day
The F-Factor Diet is a weight loss plan that focuses on high-fibre foods and lean proteins. The "F" stands for fibre, a non-digestible part of carbohydrates. The diet does not require followers to cut out fat, carbs, or alcohol. It also does not require you to exercise.
The F-Factor Diet was created by Tanya Zuckerbrot, a registered dietitian. It comes with a food line, meal plan, and other branded products. The F-Factor Diet book was released in 2006.
The diet emphasizes unprocessed carb sources like fruits, vegetables, whole grains, nuts, and seeds over processed carb sources that include refined grains and added sugar.
In Phase 1, the F-Factor Diet incorporates fewer than 35 grams of net carbs per day. This is spread over approximately three servings of carbs. This is meant to jump-start your weight loss.
To achieve the recommended 35 grams of net carbs per day, you can incorporate the following into your diet:
- High-fibre bagel waffles or crackers
- Salmon, a nutrient-dense source of lean protein and healthy fats with a reasonable amount of calories
- G-Factor Cheesy-Egg-white bites
- F-Factor 20/20 Fiber/Protein Powders, which contain 20g of belly-filling fibre
- F-Factor Kugel, a sweet treat made with vanilla 20/20 FIBER/PROTEIN powder

Stay under your daily net carb allotment
The F-Factor diet is a weight loss plan that promotes eating high-fibre foods along with lean proteins. The diet was created by New York-based registered dietitian Tanya Zuckerbrot. The F-Factor diet involves staying under your daily net carb allotment. This means limiting your intake of simple carbohydrates to the amount allowed in each step of the diet. The daily net carb allotment increases incrementally as you progress through the three steps of the plan. In step one, you are allowed 35 grams of net carbs, in step two, this increases to 75 grams, and in step three, you are allowed up to 125 grams of net carbs per day.
The F-Factor diet does not recommend calorie-counting, but there are some numbers that are useful to keep in mind. For example, knowing the number of grams of net carbs in a slice of white bread can help you make smart choices about what to eat. Additionally, while it's not recommended to have dessert every night, if you must indulge, it's best to choose something that is under 100 calories and contains less than 15 grams of net carbs.
The F-Factor diet also emphasizes flexibility and doesn't require you to restrict yourself when it comes to dining out or enjoying alcohol in moderation. The diet is designed to be more sustainable than many other dietary approaches. The combination of fibre and protein helps keep you full throughout the day while boosting your metabolism.
The F-Factor diet comes with some potential health benefits due to its high fibre content. Research shows that high-fibre diets can help lower LDL (bad) cholesterol and prevent atherosclerosis, the buildup of plaque in your arteries that can lead to heart disease. Additionally, high-fibre diets can help lower blood sugar and prevent constipation.

Adhere to recommended portion sizes
The F-Factor diet is a weight loss plan that focuses on high-fibre foods and lean proteins. The "F" stands for fibre, a nutrient that most people don't get enough of. It is a non-digestible part of carbohydrates that adds bulk to foods. The diet's creator, Tanya Zuckerbrot, a registered dietitian, recommends eating at least 35 grams of fibre per day for adults, which is in line with the Dietary Guidelines for Americans. This amount may vary depending on your age and gender.
To adhere to the recommended portion sizes, it is important to consult the F-Factor app or book. The diet encourages eating fibre-rich foods, such as GG Bran Crispbread, a specific brand of high-fibre, appetite-control crackers that can be used in place of bread to keep you full for longer. It also recommends lean proteins such as salmon, which is a nutrient-dense source of lean protein and healthy fats with a reasonable amount of calories. A 3-ounce serving of salmon provides 177 calories, 17 grams of protein, and 11 grams of fat. These nutrients promote satiety and curb cravings between meals.
The F-Factor diet also includes a line of all-natural, fibre-rich products, such as the F-Factor 20/20 Fiber/Protein Powders, which contain 20 grams of belly-filling fibre and 20 grams of muscle-building protein per serving. This product can be used in recipes like the F-Factor Kugel, a sweet treat that is filling and kosher.
While the F-Factor diet does not require you to restrict your portion sizes when eating out or drinking alcohol in moderation, it is important to be mindful of your intake. The diet focuses on curbing hunger and deprivation, and by increasing your fibre and protein intake, you can stay full throughout the day while boosting your metabolism.

Eat high-fibre carbs
The F-Factor diet is a weight loss plan that promotes eating high-fibre foods alongside lean proteins. The "F" in F-Factor stands for fibre, a nutrient that most people don't get enough of. Fibre is a non-digestible carbohydrate that adds bulk to foods without adding extra calories.
The F-Factor diet was created by New York-based registered dietitian Tanya Zuckerbrot. The diet consists of high-fibre carbs and lean protein. Zuckerbrot developed the plan after gaining 24 pounds and deciding to start eating according to the dietary advice she shared with her clients.
Identify Good Sources of Fibre
Fibre is found in fruits, vegetables, whole grains, legumes, nuts, and seeds. Non-starchy vegetables, such as beans, peas, lentils, nuts, seeds, and grains, are considered "free foods" on the F-Factor diet because they are journaled as having zero grams of carbohydrates. These foods provide essential vitamins, minerals, and additional fibre while helping to keep calorie intake in check.
Incorporate High-Fibre Foods into Your Daily Meals
The F-Factor diet emphasizes incorporating high-fibre foods into your daily meals. This may include fruits such as apples, pears, berries, and oranges; vegetables such as artichokes, avocado, sweet potatoes, and squash; whole grains such as bulgur, quinoa, barley, and whole-grain bread; and legumes such as beans, peas, chickpeas, and lentils.
Understand Net Carbs
The F-Factor diet emphasizes the concept of net carbs, which are the digestible carbs your body breaks down and absorbs after accounting for any sugar alcohol. You can calculate net carbs by subtracting the grams of fibre from the total grams of carbohydrates. For example, high-fibre bagel waffles or crackers have lower net carbs than regular bagels because the fibre content lowers the overall carb count.
Use Fibre Supplements
F-Factor offers a range of fibre supplements, such as F-Factor 20/20 FIBER/PROTEIN Powder and FIBER/PROTEIN Bars, which can help you easily incorporate fibre into your diet. These supplements come in different flavours and are gluten-free.
Be Mindful of Portion Sizes
While the F-Factor diet does not require strict calorie counting, it is important to be mindful of portion sizes. The portion of fibre in a high-carb food can only negate the carb count to a certain extent. Therefore, pay attention to the recommended serving sizes for different foods to ensure you are getting the right balance of fibre and carbohydrates.

Consume lean protein
Lean protein is an important component of the F-Factor diet, which focuses on high-fibre foods and lean proteins to promote weight loss and improve overall health. The diet was created by New York dietitian Tanya Zuckerbrot and is based on eating fibre-rich foods and lean proteins to curb hunger and promote satiety.
The F-Factor diet recommends consuming lean protein sources such as skinless poultry, fish, eggs, tofu, and Greek yoghurt. These foods are rich in protein, which helps to support muscle growth and repair, and keeps you feeling full and satisfied throughout the day. Lean proteins are also typically low in calories and fat, making them a nutritious choice for those looking to lose weight or maintain a healthy weight.
Salmon, for example, is a nutrient-dense source of lean protein and healthy fat, with a reasonable amount of calories. A 3-oz serving of salmon provides 177 calories, 17g of protein, and 11g of fat. These nutrients work together to promote satiety and curb cravings between meals, and because salmon is a lean protein, it is also carb-free. For those who don't like fish, G-Factor Cheesy-Egg-White bites can be a good source of protein.
The F-Factor diet also offers branded powders and bars that combine protein and fibre for convenient snacks. These products provide 20 grams of muscle-building protein and 20 grams of fat-fighting fibre to boost metabolism and promote satiety. They can be easily incorporated into smoothies, baked goods, or savoury dishes, making it convenient to stick to the diet even when on the go.
In addition to lean proteins, the F-Factor diet emphasises the importance of combining protein with high-fibre, complex carbohydrates. This combination helps to keep you feeling full and satisfied, while also providing your body with the energy it needs to function properly. The diet also includes "unlimited" non-starchy vegetables, which provide essential vitamins, minerals, and additional fibre, contributing to overall health and wellness.
