Keto Weight Loss: Does All American Keto Work?

The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate diet that has been touted as a weight-loss solution. The diet aims to force the body into using a different type of fuel by depriving it of carbohydrates, which are the body's preferred source of energy. Instead, the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. While the keto diet has been shown to be effective for weight loss in the short term, it is not necessarily a permanent solution as it can be restrictive and tough to sustain. There are also potential health risks associated with the diet, including high cholesterol and nutrient deficiency. As such, it is important to consult a doctor or dietitian before starting the keto diet.

What is the keto diet?

The keto diet is a low-carb, high-fat diet. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.

When this happens, your body becomes very efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.

Ketogenic diets can cause significant reductions in blood sugar and insulin levels. This, along with the increased ketones, has some health benefits.

The keto diet is a low-carb, high-fat diet. It lowers blood sugar and insulin levels and shifts the body's metabolism away from carbs and towards fat and ketones.

There are several versions of the keto diet, but the standard (SKD) version is the most researched and most recommended.

Ketosis is a metabolic state in which your body uses fat for fuel instead of carbs. It occurs when you significantly reduce your consumption of carbohydrates, limiting your body's supply of glucose (sugar), which is the main source of energy for the cells.

Following a ketogenic diet is the most effective way to enter ketosis. Generally, this involves limiting carb consumption to around 20 to 50 grams per day and filling up on fats, such as meat, fish, eggs, nuts, and healthy oils.

It's important to moderate your protein consumption because protein can be converted into glucose if consumed in high amounts, which may slow your transition into ketosis.

A ketogenic diet is an effective way to lose weight and lower risk factors for disease. Research shows that the ketogenic diet may be as effective for weight loss as a low-fat diet.

The keto diet is also said to be beneficial for people with diabetes, prediabetes, and metabolic syndrome. It can help lower blood sugar and insulin levels and improve insulin sensitivity.

The ketogenic diet has also been shown to have benefits for a wide variety of health conditions, including heart disease, cancer, Alzheimer's disease, epilepsy, and Parkinson's disease.

However, it's important to note that the keto diet has some risks and side effects. It is high in saturated fat, which has been linked to heart disease. It can also lead to nutrient deficiencies, liver problems, kidney problems, constipation, and fuzzy thinking and mood swings.

Therefore, it is important to speak to a doctor and a registered dietitian before attempting a ketogenic diet.

What are the pros and cons?

The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein eating plan that is advertised as a weight-loss solution. It is based on the idea of reaching a metabolic state called ketosis, where the body uses fat instead of carbohydrates as its primary fuel source. While the keto diet has been praised for its weight loss benefits, it is not without its drawbacks. Here are some pros and cons to consider:

Pros:

• Weight Loss: The keto diet can be effective for short-term weight loss, as it forces the body to burn fat for energy.
• Improved Insulin Sensitivity: The diet can lead to reduced insulin levels, which is beneficial for people with type 2 diabetes, prediabetes, and metabolic syndrome.
• Lower Risk of Certain Diseases: The keto diet has been linked to a reduced risk of heart disease, cancer, epilepsy, Alzheimer's disease, and other neurological conditions.
• Increased Energy: By using fat as fuel, the keto diet may provide a more stable source of energy and reduce feelings of hunger.

Cons:

• Restrictive: The keto diet is highly restrictive, eliminating most carbohydrates and requiring careful planning and preparation.
• Potential Nutritional Deficits: The diet may lead to deficiencies in micronutrients, including selenium, magnesium, phosphorus, and vitamins B and C.
• Short-Term Side Effects: "Keto flu" symptoms such as constipation, fuzzy thinking, and mood swings can occur during the initial transition period.
• Increased Cholesterol: The high consumption of saturated fats can lead to an increase in "bad" LDL cholesterol, which is linked to heart disease.
• Difficulty Sustaining: The keto diet can be challenging to maintain in the long term due to its restrictive nature and potential side effects.
• Liver and Kidney Problems: The high-fat content of the keto diet can put additional strain on the liver and kidneys, potentially worsening existing conditions.

Who should and shouldn't try it?

The keto diet is not suitable for everyone. It is a restrictive diet that can be tough to sustain and may be unhealthy for some people.

Who should try it?

The keto diet is a good fit for people with seizures. While medication is the primary treatment for epilepsy, the keto diet can help reduce the risk of breakthrough seizures.

The keto diet can also be beneficial for people looking to:

• Improve or reset their insulin sensitivity
• Improve some health biomarkers, like blood pressure
• Lose weight or body fat with a sedentary lifestyle

Who shouldn't try it?

The keto diet is not recommended for:

• People looking for quick weight loss without a long-term plan for maintaining their goal weight
• People with a poor relationship with food and/or disordered eating patterns
• People with pancreatitis, liver failure, kidney disorder, or other fat metabolism disorders
• Diabetics who have been diagnosed with diabetic ketoacidosis
• Pregnant or breastfeeding women
• Children
• Athletes or those wishing to add large amounts of muscle or weight

Additionally, ketogenic diets should be avoided if you have a rare genetic condition such as porphyria, fatty acid beta-oxidation defects, or primary carnitine deficiency.

It's important to consult a doctor or dietitian before starting the keto diet to ensure it's safe and appropriate for you.

What foods can you eat?

The ketogenic (keto) diet is a high-fat, very low-carbohydrate, and moderate-protein diet. It is important to make sure you get enough fibre and B vitamins on the keto diet.

Seafood and Meat

• Salmon, sardines, mackerel, and other fatty fish are very high in omega-3 fats, which have been associated with lower insulin levels and improved heart health.
• Shellfish like shrimp, crab, and lobster are also keto-friendly, but check the carb count as it varies by type.
• Meat and poultry are considered staple foods on the keto diet as they are high in fat and very low in carbs.
• Fresh meat and poultry contain no carbs and are rich in B vitamins and minerals.
• Bacon and sausage are allowed on keto but should be consumed in moderation as they are processed meats and not the best for your heart.

Dairy

• Cheese, cottage cheese, and Greek yoghurt are high in fat and protein and very low in carbs.
• High-fat dairy products like heavy cream, soft and hard cheeses, cream cheese, and sour cream are also keto-friendly.
• Prioritize unsweetened, higher-fat dairy products to reduce your carb intake.

Vegetables

• Non-starchy vegetables like broccoli, cauliflower, green beans, bell peppers, zucchini, spinach, cabbage, asparagus, cucumber, tomatoes, and mushrooms are low in calories and carbs but high in vitamins, minerals, and fibre.
• Avocados are also a popular choice on the keto diet as they are high in healthy fats and low in net carbs.

Nuts and Seeds

• Nuts and seeds are healthy, high in fat, and low in carbs. They are also high in fibre, which can help you feel full and lower your calorie intake.
• The best nuts to eat on the keto diet include macadamias, almonds, pecans, walnuts, and their respective butters.
• Good choices for seeds include sesame seeds, pumpkin seeds, and flaxseeds.

Berries

• Most fruits are too high in carbs to eat on the keto diet, but berries are an exception.
• Blackberries, raspberries, blueberries, and strawberries are low in carbs and high in fibre and antioxidants.

Drinks

• Unsweetened coffee and black tea are keto-friendly and can lower the risk of cardiovascular disease.
• Dry wine, champagne, and hard liquor should be enjoyed in moderation.
• Unsweetened sparkling water is a good keto-friendly alternative to soda.

What are the side effects?

The keto diet has many possible benefits, including weight loss, increased energy, and treating chronic illnesses. However, it may also have some side effects, especially at the beginning. Here are some of the potential side effects of the keto diet:

Keto Flu

One of the most common side effects of starting the keto diet is the so-called "keto flu." Symptoms can include headache, weakness, irritability, constipation, nausea, and vomiting. These flu-like symptoms are the result of the body adapting to a low-carb state and typically last only about a week.

Dehydration and Electrolyte Imbalance

The keto diet can lead to dehydration due to increased urination and the loss of fluids and electrolytes. This can cause symptoms such as lightheadedness, dizziness, and fatigue. In more severe cases, dehydration can result in kidney injury or kidney stones.

Digestive Issues

Constipation is a common side effect of the keto diet, especially in the beginning. This is often due to a lack of fiber and fluids. Some people may also experience diarrhea, which may be due to the body's difficulty in absorbing the high-fat content of the diet.

Nutritional Deficiencies

The keto diet restricts many nutrient-rich foods, including whole grains, fruits, and vegetables. As a result, people on the keto diet may not get enough vitamins, minerals, fiber, and other essential nutrients. This can lead to nutritional deficiencies and increase the risk of chronic diseases in the long term.

Bad Breath

Bad breath, often described as fruity or slightly sweet, is a common side effect of ketosis. This is caused by the increased production of acetone, a ketone that is a byproduct of fat metabolism.

Heart Palpitations

Some people on the keto diet may experience an increased heart rate or heart palpitations, especially during the first few weeks. Dehydration and low salt intake are possible contributing factors.

Kidney Stones

While uncommon, some people on the keto diet, especially those with kidney disease, may be at risk of developing kidney stones. This is due to the high-fat and animal-based food content of the diet.

High Cholesterol

The keto diet may lead to increased levels of total and LDL ("bad") cholesterol. This is a risk factor for heart disease.

Fatty Liver

Following the keto diet for an extended period may result in the development of a fatty liver.

Hypoglycemia

For individuals using medications to manage blood sugar levels, the keto diet may cause hypoglycemia. It is important to speak to a doctor before starting the keto diet to adjust any necessary medication dosages.

It is important to note that the keto diet is not suitable for everyone. People with certain medical conditions, such as chronic illnesses or a history of eating disorders, should consult a healthcare professional before starting the keto diet. Additionally, the keto diet may be challenging to follow long-term due to its restrictive nature.
