Sweet Potatoes: The Basics

How to Get 25 Grams of Fiber Into Your Low-Carb Diet

You may think sweet potatoes are just a kind of regular white potatoes. But regular potatoes are tubers and belong to the nightshade family. Sweet potatoes are an edible root and belong to the morning glory family.

Sweet potatoes have more nutritional value than white potatoes. Even though sweet potato fries are a popular dish, people don’t typically overeat sweet potatoes as they might with white potatoes.

Sweet potatoes have a lot of carbohydrates. One 5-inch sweet potato has about 26 grams of carbohydrates. In a low-carb diet, one sweet potato has half of the calories from carbohydrates that you may be allowed.

But that’s still less than the carb content of a white potato: 35 grams, on average. That’s also less than those sweet potato fries. The way they’re prepared raises their carb content to about 34 grams.

Low-carb diets that allow vegetables in moderation can include simply prepared sweet potatoes in moderation.

Is Fiber A Carbohydrate

Although most fiber sources are carbohydrates, fiber doesnt raise blood glucose, so low-carb diets dont count fiber as a carb for the purpose of tracking carbohydrate intake. However, soluble fiber provides 2 calories for every gram but not as glucose, but as a by-product of fermentation in the colon . Insoluble fiber is the only substance that provides bulk without calories.

In fact, fiber helps to moderate the effect of usable carbs in your bloodstream, so it furthers the goals of low-carb diets. To the extent that it creates satiety, it may also help prevent weight gain and aid in weight loss.

Fiber is good for your digestive system and the prevention of hypertension as well. It can also maintain healthy levels of LDL cholesterol and blood glucose while keeping your waistline and weight down.

How Many Carbohydrates Can You Eat In A Ketogenic Diet

31 High Fiber Low Carb Foods (That Taste GOOD!)

A ketogenic diet is considered a high-fat, low-carbohydrate diet. Low intake of carbohydrates causes the body to burn fat instead of carbohydrates to provide energy. In a typical ketogenic diet, carbohydrate consumption is limited to less than 50 grams per day. Daily dietary macronutrients in a ketogenic diet generally consist of 5-10 percent carbohydrates, 70-80 percent fats, and 10-20 percent proteins.

Combining Low Carb And Low Residue Diets

Hello everyone, and thank you in advance for any tips/guidance you can provide. I was diagnosed type 2 about nine months ago, and since then I have managed my BG quite successfully through diet, exercise, and medication.

I recently had my first ever colonoscopy. The recommended diet prep for that procedure was low residue . Makes sense of course but it did raise my BG levels a bit.

Without going into the details, that colonoscopy revealed the necessity for continued, and perhaps relatively frequent surgeries and procedures that will require a sustained low residue diet. Im finding it very difficult to maintain a low carb approach while eating a low residue diet. My BG levels are slowly creeping up.

Can anyone point me towards some resources that address my particular challenge of combining low carb with low residue?

Thanks again in advance!

The basics are pretty simple:

  • Eat less than 25g of net carbs per day for strict keto
  • Supplement with multivitamin, D, Omega-3 Fish oil, and electrolytes
  • Seriously, on the electrolyte front: potassium and magnesium supplements add salt to everything

So, what that often means in terms of eating: green veggies , meat, eggs, oil, and cheese. Many people eat low-carb and very high fiber , but if you aim for very low carb you can skip most of the fiber by leaving out protein bars, low-carb breads , and fiber supplements. Maybe even watch the nuts .

Can A Low Carb Diet Cause Fibre Deficiency

Its well known that a low carb diet can be beneficial for many reasons including improved blood glucose control and weight loss. However, some people may still be put off by the idea that low carb leads to deficiencies in certain nutrients including fibre which can be beneficial for digestive health.

The Guardian published an article today on a recent study which concluded that it would be difficult to meet the recommended targets for fibre intake whilst following a low carb diet. While it is true that a low carb lifestyle limits starchy vegetables and wholegrains , a low carb diet and a high fibre diet are not mutually exclusive. There is still a wide range of low carb foods, such as nuts, seeds and green veg, which can provide all the fibre you need to meet your daily recommended intake.

This has been supported by a recent study by Caryn Zinn, Amy Rush and Rebecca Johnson who compared the micronutrient values of two low carb meal plans, both oh which provided sufficient micronutrients that met the recommended values, including fibre.

Differences In Fiber And Carb Counts

5 Ways Fiber Boosts Your Low-Carb Diet Results

Your best bets for carbs are non-starchy vegetables, which are good sources of fiber while providing relatively few carbs overall. For example, cooked turnip greens offer 6 grams of total carbs in a cup with 5 grams of fiber, for a net carb count of just 1 gram. A cup of cooked cauliflower has 6 grams of carbs and 3 grams of fiber, for 3 grams of net carbs.

While a starchy veggie like sweet potato offers a lot of fiber 8 grams in a cup of mashed it also provides 58 grams of carbs, so the total net carb count is a whopping 50 grams. That could be more than your carb allotment for the day.

Fruits tend to be both high in fiber and higher in overall carbs. A cup of raw raspberries provides a hefty 8 grams of fiber with 15 grams of overall carbs, for a net carb count of 7 grams. In contrast, a cup of raw blueberries may have 4 grams of fiber, but it also supplies 21 grams of total carbs, for a net carb count of 17 grams. A dried fruit like raisins has significant fiber 11 grams in 1 cup packed but a jaw-dropping 129 grams of carbs, bringing your net carbs to 118 grams in a cup.

Consume Whole Grains Instead Of Refined Grains

Whole grains, in most cases, are minimally processed, thus leaving them intact. But refined grains undergo intense processing which strips them of their fiber-rich hull and vitamin-containing germ.

While refined grains last long, their most nutritious part is stripped away. What is left behind is nothing but fat-absorbing carb.

Therefore, replace refined grains in your diet with their whole-grain counterparts. You can go for any of the following: Oatmeal, farro, brown rice, barley, amaranth, quinoa, buckwheat, and freekeh.
