Keto Ultra Diet: Does It Work?

The keto diet is a low-carb, high-fat diet that aims to force the body to burn fat for energy instead of carbohydrates. This metabolic state is called ketosis. While the keto diet has been used to help reduce epileptic seizures, it has also been tried for weight loss. However, it is not the easiest or most sustainable diet to follow. Getting into and staying in ketosis can be challenging because it requires a specific amount of macronutrients - traditionally, 90% fat, 6% protein, and 4% carbs. The keto diet is also associated with potential health risks, such as increased bad LDL cholesterol, nutrient deficiencies, liver problems, kidney problems, and constipation. There is also a risk of scams and misleading marketing with keto products, especially supplements. Before starting any new diet, it is important to consult with a doctor or dietitian to ensure it is safe and suitable for your individual needs.

What is the keto diet?

The keto diet is a low-carb, high-fat diet. The aim is to force the body to use fat as its primary source of energy, instead of carbohydrates. Typically, a keto diet involves reducing your consumption of carbohydrates to 5-10% of your total daily calories (or 20-50 grams of carbs per day) and increasing your fat intake to 70-75% of your total calories. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes very efficient at burning fat for energy.

There are several versions of the keto diet, including the standard ketogenic diet (SKD), the cyclical ketogenic diet (CKD), the targeted ketogenic diet (TKD), and the high protein ketogenic diet. The SKD is the most researched and recommended version, consisting of 70% fat, 20% protein, and 10% carbs.

On a keto diet, you base your meals around meat, fatty fish, eggs, butter, nuts, healthy oils, avocados, and low-carb vegetables. The diet involves eliminating nearly all carbohydrates, including grains, legumes, fruits, beans, root vegetables, and sugar.

The keto diet has been associated with several health benefits, including weight loss and improved health markers such as lower blood sugar and insulin levels. It may also have benefits for certain diseases, such as diabetes, cancer, Alzheimer's, and epilepsy. However, there are also some risks and side effects associated with the keto diet, including nutrient deficiencies, liver and kidney problems, constipation, and fuzzy thinking.

Overall, the keto diet is a restrictive diet that may be challenging to follow and maintain. It is important to consult with a doctor or dietitian before starting any new diet, especially one as restrictive as the keto diet.

What can you eat on the keto diet?

The keto diet is a high-fat, low-carbohydrate eating plan. It involves drastically reducing your carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it starts burning fat as its source of fuel.

So, what can you eat on the keto diet? Here's a list of keto-friendly foods:

• Meat: Chicken, pork, steak, ground beef, lamb, bacon, turkey, ham, and sausage (in limited amounts).
• Fatty fish: Salmon, tuna, halibut, cod, trout, catfish, and mackerel.
• Shellfish: Crab, clams, oysters, lobster, and mussels.
• Eggs.
• High-fat dairy: Heavy cream, soft and hard cheeses, cream cheese, and sour cream.
• Nuts and seeds: Almonds, walnuts, macadamia nuts, pecans, hazelnuts, pumpkin seeds, and flaxseeds.
• Healthy oils: Olive oil, coconut oil, avocado oil, butter, and ghee.
• Avocados.
• Low-carb vegetables: Cauliflower, cabbage, broccoli, zucchini, green beans, peppers, eggplant, tomatoes, asparagus, cucumber, onion, mushroom, spinach, lettuce, and olives.
• Berries: Blueberries, blackberries, raspberries, and strawberries (in moderation).

It's important to note that the keto diet is restrictive, and not all fruits and vegetables are allowed. Starchy vegetables like potatoes and sweet potatoes, and fruits like bananas and mangoes, are not keto-friendly. Whole grains, legumes, and processed foods are also off the menu.

What are the health benefits of the keto diet?

The keto diet is a low-carb, high-fat diet that offers many health benefits. Here are some of the health benefits of the keto diet:

• Weight loss: The keto diet can help you lose weight and lower your risk for certain diseases. Research shows that the keto diet may be as effective for weight loss as a low-fat diet.
• Lowered risk of certain diseases: The keto diet can help lower your risk of diabetes, cancer, epilepsy, Alzheimer’s disease, Parkinson’s disease, and polycystic ovary syndrome.
• Improved heart health: The keto diet can help improve risk factors like body fat, HDL (good) cholesterol levels, blood pressure, and blood sugar.
• Increased energy: Ketones, which are produced when the body is in a state of ketosis, can be used as fuel for the body and brain. This can lead to increased energy levels.
• Reduced hunger: The keto diet is so filling that you can lose weight without counting calories or tracking your food intake.
• Improved skin health: Eating a diet high in processed and refined carbohydrates may adversely affect skin health. By decreasing carb intake, the keto diet could reduce acne symptoms in some people.

What are the risks of the keto diet?

The keto diet is a low-carb, high-fat diet that has gained popularity in recent years. While it has been shown to be effective for weight loss and improving health, there are several risks associated with the keto diet that you should be aware of.

Firstly, the keto diet is high in saturated fat, which has been linked to heart disease. The diet is associated with an increase in "bad" LDL cholesterol, which is a risk factor for heart disease.

Secondly, the keto diet may lead to nutrient deficiencies, especially if you are not eating a variety of vegetables, fruits, and grains. You may be at risk of deficiencies in micronutrients such as selenium, magnesium, phosphorus, and vitamins B and C.

Thirdly, the keto diet could cause liver problems, especially if you already have a liver condition. With such a high amount of fat to metabolize, the liver may be overloaded and its function may be affected.

Fourthly, the keto diet may cause kidney problems. The kidneys help metabolize protein, and the high protein content of the keto diet may overload them. This is of particular concern for individuals with chronic kidney disease (CKD), as the diet may lead to a state of acidosis and worsen the progression of CKD.

Fifthly, the keto diet is often low in fiber, which can lead to constipation and digestive issues. The diet restricts high-fiber foods such as grains, legumes, and certain fruits and vegetables, which can impact gut health and cause constipation.

Finally, the keto diet may cause fuzzy thinking and mood swings. The brain typically functions best when using glucose from carbohydrates as its primary energy source. When following a low-carb diet like keto, the brain may not have sufficient glucose, which can lead to confusion and irritability.

It is important to consult with a doctor and a registered dietitian before starting the keto diet to ensure that it is safe for you and to minimize the risks outlined above.

What are keto supplements?

Keto supplements, which usually come in powder or capsule form, contain two main ingredients: medium-chain triglycerides (MCTs) and exogenous ketones or ketone salts (beta-hydroxybutyrate, or ketones made outside the body in a lab).

MCTs are predominantly saturated fats that break down in the liver. The body can use MCTs as a source of energy when in ketosis.

Exogenous ketones are ketones that are made outside the body in a lab. They are also known as ketone salts or ketone beta-hydroxybutyrate (BHB). BHB is a compound that the liver produces from fats. These small molecules circulate in the bloodstream and are used by the body's tissues for energy.

Together, MCTs and exogenous ketones work to increase the amount of fat in the body and kick it into ketosis (the fat-burning zone) faster. Ketone supplements also allegedly block carbs from being absorbed or metabolised.

However, there is limited peer-reviewed research on the effectiveness of keto supplements. One 2021 study found that consuming BHB supplements for six weeks enhanced ketosis in a group of people who were already following a keto diet, but there were no significant health benefits or weight loss compared to the group that did not take BHB supplements.
