Fiber And Carb Counting On Keto: What's The Link?

The Ketogenic Diet is a low-carbohydrate method of eating that can help with diabetes, epilepsy, autoimmune disorders, acid reflux, inflammation, hormonal imbalances, and other issues. A key component of the keto diet is calculating net carbs, which are the carbs that are absorbed by your body and can be used for energy. The formula for calculating net carbs is: grams of total carbs – fiber – sugar alcohols = net carbs. However, the term net carbs is not recognised by the FDA, and nutrition experts dispute its validity. The calculation of net carbs can be confusing due to conflicting and outdated information, and it is not clear whether counting net carbs will help or hinder weight loss efforts.

The FDA does not recognise the term net carbs

The term "net carbs" is disputed among nutrition experts. The Food and Drug Administration (FDA) does not recognize the term "net carbs". The FDA recommends using the total carbohydrates listed on the nutrition label. This is because there is no legal definition of the "net", "active", or "impact" carbs that are increasingly popping up on food labels and in advertisements. The only carbohydrate information regulated by the FDA is provided in the Nutrition Facts label, which lists total carbohydrates and breaks them down into dietary fibre and sugars.

Any information or claims about carbohydrate content that appear outside that box have not been evaluated by the FDA. Wahida Karmally, DrPH, RD, and director of nutrition at the Irving Center for Clinical Research at Columbia University, says that these terms have been made up by food companies. She says that it is a way for manufacturers to draw attention to their products and make them look appealing by saying, "Look, you can eat all these carbs, but you're really not impacting your health, so to speak".

The concept of net carbs is based on the principle that not all carbohydrates affect the body in the same manner. Some carbohydrates, like simple or refined starches and sugars, are absorbed rapidly and have a high glycemic index, meaning they cause blood sugar levels to quickly rise after eating. Excess simple carbohydrates are stored in the body as fat. Examples of these include potatoes, white bread, white rice, and sweets.

Other carbohydrates, such as the fiber found in whole grains, fruits, and vegetables, move slowly through the digestive system, and much of it isn't digested at all (insoluble fiber). In calculating net carbs, most manufacturers take the total number of carbohydrates a product contains and subtract fiber and sugar alcohols because these types of carbohydrates are thought to have a minimal impact on blood sugar levels.

However, researchers say the impact of sugar alcohols on blood sugar levels and the body is not fully understood, and they may also cause problems in some people. Karmally says that there are some sugar alcohols that can raise blood sugar. Certain sugar alcohols do have a higher glycemic index, and they are still not counted as carbohydrates by these companies. She adds that the use of terms like "net carbs" is confusing for people with diabetes, who may think it is fine for them to consume as much as they want.

Until the FDA takes action on the issue, experts say that people are probably better off eating foods that are naturally low in refined carbohydrates, such as fruits and vegetables, rather than highly processed foods like snack bars, pastas, and sweets that have had their natural carbohydrates stripped away.

The FDA recommends using the total carbohydrates listed on the nutrition label

The FDA's Obesity Working Group has advocated for a simple "calories count" approach to battling obesity and helping people make healthy food choices. In their report, the group concluded that there is "no substitute for the simple formula that 'calories in must equal calories out' in order to control weight".

The concept of net carbs is based on the principle that not all carbohydrates affect the body in the same way. Some carbohydrates, like simple or refined starches and sugars, are absorbed rapidly and have a high glycemic index, meaning they cause a quick rise in blood sugar levels after eating. Other carbohydrates, such as the fibre found in whole grains, fruits and vegetables, move slowly through the digestive system and are not digested at all.

When calculating net carbs, most manufacturers take the total number of carbohydrates a product contains and subtract fibre and sugar alcohols because these types of carbohydrates are thought to have a minimal impact on blood sugar levels. However, the impact of sugar alcohols on blood sugar levels and the body is not yet fully understood, and they may cause problems in some people.

Due to conflicting and outdated information, figuring out how to calculate net carbs can be confusing. The key is to eat the number of carbs that allows you to achieve your health goals, regardless of how you count them.

Nutritional labels differ between countries

In the EU, nutrition labels are technically voluntary, and mandatory labelling requirements are far more flexible than in the US. The EU's provision on the required content and presentation of nutrition labels is very similar to the FDA's rules, and is also based on international standards set up by the Codex Alimentarius Commission. However, the EU does not require the indication of the number of servings per container, and all calorie listings are based on 100g or 100ml, rather than per serving. The EU also lists salt content (in grams) rather than sodium content (in milligrams), and requires specific information on the vegetable origin of refined oils and fats. Food additives are also labelled differently in the EU, with common additives assigned an identifying three or four-digit code, or E number, rather than being referenced by their common names as in the US.

Other countries have their own unique nutritional labelling systems. In the UK, the government has adopted a colourful traffic light system to convey nutritional information, allowing consumers to tell at a glance whether a product is high, medium or low in fat, saturated fat, sugar and salt. In Australia and New Zealand, a simple star system is used, with half a star representing something with virtually no nutritional value, and five stars for the healthiest products. Mexico has replaced its daily guideline tables with a series of black octagon "STOP" signs, each with a warning such as "EXCESS SODIUM" or "EXCESS SUGAR".

Net carbs are the carbs in food that you digest and use for energy

Net carbs are the carbohydrates in food that you digest and use for energy. They are also referred to as digestible or impact carbs. Net carbs are absorbed by the body and include both simple and complex carbs. Simple carbs contain one or two sugar units linked together and are found in foods like fruits, vegetables, milk, sugar, honey, and syrup. Complex carbs, on the other hand, contain many sugar units linked together and are found in grains and starchy vegetables like potatoes.

When you eat a carb-containing food, most of the carbs are broken down into individual sugar units by enzymes produced in your small intestine. However, some carbs, like fiber and sugar alcohols, can't be broken down into individual sugars or are only partially broken down and absorbed. This is why you can subtract most fiber and sugar alcohol content from your daily carb total.

The concept of net carbs is important for those following a ketogenic diet. The ketogenic diet is a low-carbohydrate method of eating that can help with weight loss and various health issues such as diabetes, epilepsy, and autoimmune disorders. On a keto diet, eating too many carbs can prevent you from reaching and maintaining ketosis, a metabolic state where your body shifts from burning carbs for energy to burning fat for fuel.

It's important to note that the term "net carbs" is not recognized by the Food and Drug Administration (FDA), and there is no official definition. This means that food manufacturers' calculations of net carbs can vary. Additionally, nutritional label guidelines differ between countries, with the US and Canada including fiber as part of the total carbohydrates, while most other countries do not. Therefore, it's essential to read nutrition labels carefully and understand how net carbs are calculated to ensure accuracy in your diet.

Eating too many carbs can kick you out of ketosis

The keto diet is a very low-carb, high-fat diet that's popular for its weight loss effects. Ketosis is a metabolic state in which your body burns fat as its primary source of energy instead of carbs. Typically, your body uses blood sugar (glucose) as its key energy source. This glucose is derived from eating carbohydrates such as starches and sugars.

When your carb intake is very low, your body doesn't have enough carbs to burn for energy, so it burns fat instead. As your body breaks down fat, it produces a compound called ketones, which become your body and brain's main source of energy.

To stay in ketosis, you need to eat fewer than 50 grams of carbs per day. Eating more than 50 grams can kick you out of ketosis. As carbs are your body's preferred energy source, your body will use them over ketone bodies (derived from fats) as soon as a sufficient number of carbs are available.

Because 50 grams of carbs is a relatively small amount, a single cheat meal can easily exceed your daily carb allowance and take your body out of ketosis. A cheat day is almost certain to surpass 50 grams of carbs. It's important to note that it takes several days to one week to get back into ketosis after being kicked out.

Some research suggests that suddenly reintroducing a high-carb meal to a ketogenic diet may damage your blood vessels. It's also easy to overeat while cheating, which may sabotage your weight loss efforts and promote unhealthy eating habits. Therefore, cheat meals or days are discouraged on the keto diet because they can easily break ketosis.

If you've cheated on keto and want to get back into ketosis, there are a few techniques you can try:

• Intermittent fasting: Combine intermittent fasting with the keto diet to help your body shift its fuel source from carbs to fat.
• Track your carb intake: Keep a close eye on your daily carb intake to ensure you don't underestimate it.
• Try a short-term fat fast: Fat fasts like egg fasts are very high-fat, low-carb diets meant to be brief and can help expedite ketosis.
• Exercise more: Physical activity depletes your glycogen stores, which are your body's stored form of carbs, thus promoting ketosis.
• Try a medium-chain triglyceride (MCT) supplement: MCTs are rapidly absorbed fatty acids that are easily converted into ketones.
