How much fiber do I need?

In paleolithic times, scientists estimated that humans were consuming about 150g of fiber a day. Today we are eating more like 15 grams per day, many from concentrated sources of carbohydrates, not nutrient dense vegetables.[efn_note] Lugavere, M. & Grewal, P.

The FDA recommends around 25-30g of fiber per day. If you’ve eliminated grains and legumes to balance blood sugar, support your gene expression and lower inflammation, then you’ll need to look at these keto-friendly fiber sources:

Since your body doesn’t absorb fiber, it isn’t considered an essential nutrient; however, a diet lacking in fiber can be filled with health problems.

The benefits of fiber

Fiber contributes to regularity and wards off constipation. It can help in weight loss and maintenance by making you feel full and satisfied.[efn_note] “Making one change — getting more fiber — can help with weight loss ….” 9 Apr. 2015, https://www.health.harvard.edu/blog/making-one-change-getting-fiber-can-help-weight-loss-201502177721.

Blood sugar

Fiber plays a role in blood sugar regulation. If you’re new to the ketogenic lifestyle and want to avoid the mood dips that sometimes accompany blood sugar drops when adopting a low carb eating template, fiber is your friend.

Gut health

Fiber feeds the microbes in your intestines. As it hangs out in your digestive tract, it begins to ferment. Then, the beneficial bacteria in your gut eats it. Then, they produce short-chain fatty acids, which might be helpful in warding off IBS, Crohn’s and heart disease while also protecting the lining of your colon.[efn_note] “High dietary fiber intake linked to health promoting … – ScienceDaily.” 29 Sep. 2015, https://www.sciencedaily.com/releases/2015/09/150929070122.htm.

Helpful Tips to Get more Fiber on Keto

If you find yourself at the store unable to remember the fiber content of your favorite keto foods, here are some helpful hints.

Get fiber on keto! Tip #1: Choose Green Vegetables. Skip juice, opt for green smoothies instead of fruit-heavy ones, cook down greens in a skillet.

1. Choose green vegetables

If it’s a vegetable, and it’s green, it’s likely a pretty good candidate for a fiber source. Still, being a bit more educated on higher fiber fare in veggie form can come in handy.  Avocados and brussel sprouts top the list in terms of most fiber for a 1 cup serving. Take note of these other green veggie options: broccoli, zucchini, kale, spinach, romaine, artichoke. Fresh salads are an easy way to incorporate many of these leafy greens.

Skip the green juice

At first thought, green juicing might sound like a good avenue for upping your green veggie game; however, the juicing process eliminates the fiber since the fiber-filled skin and pulp are tossed aside.

Grab a green smoothie

If you love green veggies through a straw, consider going green in the smoothie department. Use an avocado for a creamy base and a bunch of fiber. Add frozen cauliflower, broccoli, spinach or other leafy green and a tablespoon or two of chia seeds. Zucchini is another green, fiber-filled vegetable that lends a creamy texture to smoothies without an overpowering veggie taste. However, be sure to measure and manage your portions here and not going over your unique carb tolerance.

Cook down your greens

A better option is to skip the straw, and just cook down your greens in a skillet. Spinach, kale and collard greens are excellent choices. You’ll be getting almost 8g of fiber from 1 cup of cooked collard greens , 4g from spinach  and 5g from kale. Cook greens down with a bit of olive oil or chicken broth, to get both flavor and fiber.

2. Swap high carb foods with fiber-rich vegetables

Get fiber on keto! Tip #2: Replace high carb foods with fiber-rich vegetables. Try to replace white rice with riced cauliflower or broccoli, give zucchini noodles a whirl and make avocado pudding by adding frozen berries and coconut milk or water to an avocado. Stevia optional.

Here are some easy food changes to get more fiber on keto:

Cauliflower rice: Consisting of only cauliflower cut into small rice-sized bites, this product has become widely available at grocery stores nationwide. Check your freezer and refrigerator sections. Use this as a rice replacement or just throw it in a skillet of browned meat, add chicken broth and make faux mashed potatoes, mix with flax and eggs to form a pizza crust or add a bit to thicken a green smoothie or soup. Go the DIY route by using a food processor and the top of a fresh head of cauliflower. Process until desired consistency.

Broccoli rice: This is the same concept as the cauliflower rice mentioned above, but it uses broccoli. Consider stirring in your egg mixture when baking egg muffins.

Zucchini noodles: Also known as “zoodles,” these long strands of zucchini can be used in place of spaghetti. Toss in olive oil on a skillet with fresh basil, mushrooms and cherry tomatoes. Many stores carry pre-cut zoodles, or you can make your own by using a spiralizer.

Avocado pudding: All it takes is some beautifully ripe avocados, some blueberries and a bit of collagen or Bone Broth Protein powder.

3. Pick fibrous snacks

How to get enough fiber on keto! Tip #3: Try Fiber-filled snacks. Eat coconut flakes, berries and nuts. Try seeds if you tolerate them and aren't trying to lose weight.

Berries

Not only are blueberries, raspberries, strawberries and blackberries delicious, they also contain vitamins A, C, K and B. A single cup of most berries offers around 8 g of fiber, too.

Coconut Flakes

Dried unsweetened coconut flakes are an unsweetened, fiber-filled treat. One cup of dried coconut flakes offers 7.2 g of fiber as well as selenium, folate and manganese.

3 Ways to Enjoy Coconut Flakes: Freezer, Bag, Skillet

Snack on them straight from the bag, or toss some in the freezer for an added crunch. Alternatively, add a tablespoon or two of coconut oil in a skillet with 2 cups of large unsweetened coconut flakes. Add 1 tsp of cinnamon (or more if you’d like) and a dash of sea salt. Toast on medium high. This is delicious served warm right off the skillet or cooled off a day later.

Coconut and Berries Make a Winning Fiber Treat

Take a ½  c frozen berries, heat on low and top with coconut flakes for a yummy treat full of fiber and a lovely crunch.

Nuts and Seeds

Nuts and seeds can be a nutritious, fiber-filled option for a ketogenic eating template. Those trying to lose inflammation and unwanted weight or who are sensitive to nuts might try opting for raw or dry roasted sunflower seeds, pumpkin seeds, chia seeds, flaxseed or hemp hearts. If nuts aren’t a problem for you, try almonds, walnuts, Brazil nuts, pecans or the keto-friendly macadamia nut. These buttery-rich nuts are delicious, filling, a good monounsaturated fat source and have a low carbohydrate count.

A keto diet can be a fiber-rich diet

Don’t sacrifice your fiber intake on a low carb, ketogenic diet. Instead, opt for these fiber-rich vegetables, fruits and seeds.
