Beta-Keto For All: Does It Work Universally?

The keto diet is a high-fat, low-carb, and moderate-protein eating plan that was initially developed in the 1920s to treat epilepsy. While it has gained popularity as a weight-loss strategy, it is not suitable for everyone due to its restrictive nature, potential nutritional deficiencies, and difficulty in maintaining long-term. The keto diet may be beneficial for specific populations, such as people with seizures or type 2 diabetes, but it is not recommended for individuals with certain health conditions, pregnant or breastfeeding women, children, or those with a history of disordered eating. Before considering the keto diet, it is essential to consult a healthcare professional to assess individual needs and potential risks.

Who should try the keto diet?

The keto diet is not suitable for everyone. However, it can be greatly beneficial to some.

The keto diet is the standard treatment for treatment-resistant epilepsy. It has been used for over a century to help alleviate epileptic seizures, especially in children. It is believed that the combination of high-fat and low-sugar content reduces the "excitability" of the brain, thus reducing seizures.

The keto diet can also be a powerful intervention for people with the following conditions:

• Type 2 diabetes: The keto diet can help reverse diabetes, reduce weight, and lower the need for insulin and oral hypoglycemic drugs.
• Class III obesity: For those with a body mass index (BMI) over 40, or with insulin resistance without Type 2 diabetes, the keto diet can be a useful short-term strategy to reset metabolism.
• Alzheimer's disease and autism: Research suggests the keto diet might also help those with Alzheimer's and autism, though more research is needed.

The keto diet can also be beneficial for those who:

• Are looking to improve or reset their insulin sensitivity.
• Want to improve some health biomarkers, like blood pressure.
• Want to lose weight or body fat with a sedentary lifestyle.

It is important to note that the keto diet is not suitable for everyone. It is not recommended for individuals with specific health conditions, pregnant or breastfeeding women, children, or those with a history of disordered eating. It is always best to consult a doctor or healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

Who shouldn't try the keto diet?

The keto diet is not suitable for everyone. Here are some groups of people who should not try the keto diet:

• Those looking to lose weight quickly without a long-term plan to maintain weight loss.
• People with a history of disordered eating or a poor relationship with food.
• People with fat metabolism disorders, such as pancreatitis, liver failure, or kidney disorders.
• Pregnant or breastfeeding women, unless otherwise instructed by a physician.
• Children, unless otherwise instructed by a physician.
• People with type 1 diabetes, especially if they have ever been diagnosed with diabetic ketoacidosis.
• People with a rare genetic condition, such as porphyria, fatty acid beta-oxidation defects, or primary carnitine deficiency.
• Athletes who engage in high-intensity workouts that engage fast-twitch muscles.
• People with kidney damage, liver conditions, or heart disease.
• Anyone considering the diet as an experiment or short-term fix without proper medical supervision.

What foods can you eat?

The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. Here is a list of foods that you can eat on a keto diet:

Meat and Poultry

Meat and poultry are considered staple foods on the keto diet. They are rich in B vitamins and several important minerals. They’re also a great source of high-quality protein, which may help preserve muscle mass during a very low-carb diet. The best meats to eat while on the keto diet include chicken, pork, steak, ground beef, lamb, bacon, turkey, ham, and sausage (in limited amounts).

Fish and Shellfish

Fish and shellfish are very keto-friendly. Salmon and other fish are not only nearly carb-free but also rich in B vitamins, potassium, and selenium. Salmon, sardines, mackerel, and other fatty fish are very high in omega-3 fats, which are linked to reducing the risk of chronic disease. Shellfish such as shrimp, crab, clams, oysters, lobster, and mussels are also keto-friendly, but it’s important to carefully track these carbs to stay within your range.

Eggs

Eggs are an extremely healthy protein source. Each large egg contains less than 1 gram of carb and about 6 grams of protein, making them ideal for keto. In addition, eggs have been shown to trigger hormones that increase feelings of fullness. It’s important to eat whole eggs rather than egg whites since most of an egg’s nutrients are found in the yolk.

Dairy and Dairy Alternatives

There are hundreds of types of cheese, most of which are very low in carbs and high in fat, making them a great fit for the keto diet. Cheese is also a good source of calcium and protein. Other keto-friendly dairy and dairy alternatives include plain Greek yogurt, cottage cheese, cream, half-and-half, and certain unsweetened plant milks such as soy, almond, and coconut milk.

Vegetables

Non-starchy vegetables such as broccoli, cauliflower, green beans, bell peppers, zucchini, spinach, kale, tomatoes, cucumbers, onion, mushroom, lettuce, and olives are keto-friendly. These veggies are low in calories and carbohydrates but packed with vitamins, minerals, and fiber.

Fruits

Most fruits are too high in carbs to eat on the keto diet, but berries are an exception. They are low in carbs and high in fiber, and rich in nutrients, namely antioxidants. The most keto-friendly berries include blackberries, raspberries, strawberries, and blueberries.

Nuts and Seeds

Nuts and seeds are healthy, high in fat, and low in carbs. They are also high in fiber, which can help you feel full and naturally lower your calorie intake. The best nuts to eat while on the keto diet include macadamias, almonds, pecans, walnuts, pumpkin seeds, sesame seeds, and flaxseeds.

Beverages

Unsweetened coffee and black tea are keto-friendly. Dry wine, champagne, and hard liquor should be enjoyed sparingly. Unsweetened sparkling water is also a great choice.

Is the keto diet healthy?

The ketogenic or keto diet is a high-fat, low-carbohydrate diet that produces metabolic changes associated with the starvation state. It was originally developed in the 1920s as a treatment for epilepsy.

The keto diet is advertised as a weight-loss wonder, but it is a medical diet that comes with serious risks and is not suitable for everyone. It is extremely strict and difficult to maintain, and it may not be realistic or sustainable long-term.

The keto diet is high in saturated fat, which has been linked to heart disease. It is also associated with an increase in "bad" LDL cholesterol, which is also linked to heart disease. The diet could also lead to nutrient deficiencies, liver problems, kidney problems, constipation, and fuzzy thinking and mood swings.

Some people may benefit from the keto diet, including those who need help lowering their blood sugar levels and losing weight. Multiple studies have shown that the keto diet improves glycemic control while contributing to weight loss. The diet can also help people who are looking to improve or reset their insulin sensitivity or improve some health biomarkers, like blood pressure.

However, the keto diet is not recommended for individuals with specific health conditions, pregnant or breastfeeding women, children, or those with a history of disordered eating. It can also be difficult to maintain due to its restrictive nature and potential nutritional deficits.

Before starting any new diet, it is important to consult a doctor or registered dietitian to ensure it is safe and appropriate for your individual needs and health status.

What are the risks?

The keto diet is not suitable for everyone. Here are some of the risks associated with the diet:

Keto Flu

As your body adjusts to the diet, you may experience flu-like symptoms such as headaches, dizziness, fatigue, nausea, and constipation. These symptoms are often caused by dehydration and electrolyte imbalances. Most people feel better within a few weeks, but it's important to monitor these symptoms and stay hydrated.

Kidney Problems

The high intake of animal foods on the keto diet can lead to an increased risk of kidney stones. This is because animal foods can cause your blood and urine to become more acidic, leading to increased calcium excretion in your urine. The keto diet may also overload your kidneys with protein. People with chronic kidney disease should avoid the keto diet as it can worsen their condition.

Digestive Issues and Gut Bacteria Changes

The keto diet restricts carbs, making it difficult to meet your daily fiber needs. This can lead to digestive discomfort and constipation. In addition, the low carb and fiber intake may negatively affect your gut bacteria, potentially impacting immunity, mental health, and inflammation.

Nutrient Deficiencies

The keto diet restricts many nutrient-dense foods, such as fruits, whole grains, and legumes. This may lead to deficiencies in vitamins and minerals such as calcium, vitamin D, magnesium, and phosphorus. Over time, this can result in nutrient deficiencies.

Low Blood Sugar

Individuals with type 1 diabetes may be at a higher risk of hypoglycemia (low blood sugar) while on the keto diet. This can lead to confusion, shakiness, fatigue, and sweating, and if left untreated, hypoglycemia can be fatal.

Bone Health

Several studies have linked the keto diet to decreased bone strength and bone mineral density. This may be due to the body's adaptation to ketosis.

Increased Risk of Chronic Diseases and Early Death

There is some evidence to suggest that the keto diet, which focuses on animal-based and high-fat foods, may lead to poor health outcomes. Some studies have linked animal-based low-carb diets to higher rates of death from heart disease, cancer, and all causes. However, more research is needed in this area.
