Non-Absorbable Carbs: Friend Or Foe Of Keto Diets?

The keto diet is a low-carb, high-fat diet that aims to force the body into a metabolic state called ketosis, where the body burns fat for fuel instead of carbohydrates. While the keto diet has been linked to weight loss and improved blood pressure, it is highly restrictive and may lead to several health issues such as nutrient deficiency, liver and kidney problems, constipation, and fuzzy thinking. Non-absorbable carbs are typically high in fibre and low in net carbs, which are calculated by subtracting the amount of fibre from the total number of carbs. While non-absorbable carbs may technically be consumed on the keto diet, they may interfere with ketosis and the overall effectiveness of the diet.

Non-absorbable carbs are not the only foods to avoid on keto

The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, only 5% to 10% of energy intake comes from carbohydrates. This reduction in carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into molecules called ketone bodies to use for energy.

To stay in ketosis, it is recommended to limit carb intake to 20-50 grams per day. This can be challenging, as many foods contain carbohydrates. Here are some foods that should be limited or avoided on the keto diet:

• Starchy vegetables: Potatoes, sweet potatoes, corn, and beets are high in carbohydrates and should be limited.
• High-sugar fruits: Bananas, raisins, dates, mangoes, and pears are high in natural sugars and can spike your blood sugar levels.
• Bread, pasta, and rice: These refined carbs are high in carbohydrates and can prevent a ketogenic state if consumed in large amounts.
• Beer and mixed drinks: Alcoholic beverages, especially those with added sugars, are high in carbohydrates and low in nutrients.
• Honey, syrup, and sugar: These are concentrated sources of sugar and can easily increase your daily carb count.
• Glazed or honey-baked ham: The sugar content in these processed meats can interfere with ketosis.
• Low-fat or reduced-fat foods: These are often higher in sugar and lower in fat, which is the main source of fuel on the keto diet.
• Dried fruit or trail mix: The sugar in fruit is concentrated in dried fruit, making it high in carbohydrates.
• Beans and legumes: While these are nutritious, they are also high in carbohydrates and should be limited.
• Milk: Whole milk contains 11 grams of carbohydrates per cup and should be limited or avoided.

It is important to note that the keto diet is not suitable for everyone. It can be harmful to people with type 2 diabetes who are on insulin and those with type 1 diabetes who need to take insulin. Additionally, the keto diet may not be safe for those who are breastfeeding or have certain metabolic conditions. It is always recommended to consult with a doctor or registered dietitian before starting any new diet, especially a restrictive one like the keto diet.

The keto diet is high in fat, moderate in protein, and very low in carbs

The keto diet is a high-fat, moderate-protein, and very low-carb diet. It is an extremely low-carb, high-fat diet that aims to put your body in a metabolic state of ketosis, where it burns fat instead of carbs for energy.

On a keto diet, carbohydrates are typically restricted to 20-50 grams per day. This total does not include the portion of carbs made up of dietary fibre, as these are not digested by the body. On a 2,000-calorie diet, a keto diet will typically consist of 55-60% fat, 30-35% protein, and 5-10% carbs.

To achieve ketosis, it is important to avoid eating too many carbs. The fewer carbs you eat, the more effective the diet appears to be for reaching ketosis and losing weight. In addition to limiting carbs, it is also important to get enough protein. Most people need at least 70 grams of protein per day, or 20-35% of calories from protein.

The keto diet includes foods such as:

• Red meat (beef, pork, lamb)
• Poultry (chicken, turkey)
• Fish (salmon, tuna, sole, trout, halibut)
• Natural fats (butter, olive oil)
• Above-ground vegetables (leafy greens, broccoli, cauliflower, tomatoes, eggplant)
• Nuts and seeds (almonds, walnuts, pumpkin seeds, sunflower seeds, pistachios, cashews)
• High-fat fruits (avocado, coconut)
• Eggs

The keto diet excludes foods such as:

• Bread, tortillas, muffins, bagels, pancakes
• Cakes, cookies, and other baked goods
• Sugar and sugary foods/drinks
• Most fruits and fruit juices
• Starchy vegetables (peas, corn, potatoes)
• Beans and legumes
• Dairy (milk, yoghurt)
• Condiments with added sugar (ketchup, barbecue sauce, salad dressings)
• Alcohol

The keto diet is generally safe but may not be suitable for everyone

The keto diet is a low-carb, high-fat diet. It can be effective for weight loss and certain health conditions, such as improving type 2 diabetes or metabolic syndrome. On a keto diet, you cut back significantly on carbohydrates to burn fat for fuel. This can put your body into a metabolic state called ketosis, where your liver turns fat into small energy molecules called ketones, which your brain and other organs can use for energy.

While the keto diet is generally safe, it may not be suitable for everyone. It is highly restrictive and very high in fat, and the long-term health effects are not well understood. The diet may also be challenging to maintain due to the restriction of several food groups, including grains, fruits, starchy vegetables, legumes, and dairy.

• Nutrient deficiencies: A keto diet may be low in certain micronutrients, such as selenium, magnesium, phosphorus, and vitamins B and C, which are abundant in fruits, vegetables, and whole grains.
• Liver problems: The high-fat content of the keto diet may put additional strain on the liver and worsen existing liver conditions.
• Kidney problems: The kidneys help metabolize protein, and a keto diet may overload them, especially if you are not careful about your protein intake.
• Constipation: The keto diet is low in fibrous foods like grains and legumes, which can lead to constipation.
• Fuzzy thinking and mood swings: The brain typically functions best when using glucose from carbohydrates as its primary energy source. Low-carb diets may cause confusion and irritability.
• Increased "bad" LDL cholesterol: The keto diet is associated with an increase in LDL cholesterol, which is a risk factor for heart disease.
• Not suitable for everyone: The keto diet may be harmful to people with type 2 diabetes who are on insulin and those with type 1 diabetes. It is also not recommended for breastfeeding women and people with certain rare metabolic conditions.
• Challenging to maintain: The keto diet is highly restrictive, and it can be challenging to meet nutritional needs and maintain the diet long-term.
• Side effects: The keto diet may cause side effects like the "keto flu," bad breath, hair loss, and damaged gut health.

Before starting a keto diet, it is essential to consult with a healthcare professional, especially if you have any health conditions or are taking medications. While the keto diet can be effective for some people, it is not a one-size-fits-all solution, and it may not be suitable for everyone.

The keto diet can be beneficial for weight loss and certain health conditions

The keto diet is a low-carb, high-fat diet. It can be beneficial for weight loss and certain health conditions, as demonstrated in many studies.

On a keto diet, you cut back significantly on carbohydrates to burn fat for fuel. This can put your body into a metabolic state called ketosis, where your liver turns fat into small energy molecules called ketones, which your brain and other organs can use for energy.

The keto diet has been shown to be effective for losing weight. More than 35 scientific studies show that, when compared to other diets, low-carb and keto diets lead to greater weight loss. This is because being in ketosis lowers insulin levels, which can help you access your body fat stores more easily.

Keto diets may also have other positive health effects, such as reducing blood sugar levels, improving metabolic health and blood pressure, and controlling type 2 diabetes.

However, there are some potential risks and side effects associated with the keto diet. It is high in saturated fat, which is linked to heart disease. It may also lead to nutrient deficiencies, liver problems, kidney problems, constipation, and fuzzy thinking and mood swings.

Overall, the keto diet can be beneficial for weight loss and certain health conditions, but it is important to consult with a doctor or dietitian before starting this or any other restrictive diet.

The keto diet may have some downsides and side effects

The keto diet is a low-carb, high-fat diet. It can be effective for weight loss and certain health conditions. However, it may have some downsides and side effects.

Firstly, the keto diet is highly restrictive, and it can be challenging to meet nutritional needs while following it. It may also be difficult to sustain in the long term. The diet is very high in fat, and most of the allowed fat sources are saturated, which have been linked to an increased risk of heart disease.

Secondly, the keto diet may cause nutrient deficiencies, especially in vitamins and minerals usually obtained from plant foods. It may also worsen existing liver conditions due to the high amount of fat that needs to be metabolised. The kidneys may also be overloaded as they help metabolise protein, and the keto diet typically includes large amounts of protein.

Thirdly, the keto diet is low in fibrous foods, which can lead to constipation. It may also cause fuzzy thinking and mood swings as the brain functions best when it uses sugar from carbohydrates as its energy source.

Finally, the keto diet can cause side effects such as bad breath, hair loss, and damaged gut health. It may also lead to a condition called 'keto flu', which includes symptoms such as difficulty focusing, less energy, and increased thirst and urination.

Overall, while the keto diet may have some potential benefits, it is important to be aware of the possible downsides and side effects. It is recommended to consult a doctor and a registered dietitian before starting this or any other restrictive diet.
