Over the years, the ketogenic diet has experienced a surge in popularity, as many individuals and athletes have adopted it to improve their overall physical health and fitness. The ketogenic diet is a high-fat, low-carbohydrate diet that has been suggested to have numerous health benefits, such as reducing the risk of heart disease, improving cognitive health, and promoting weight loss.
The Paleo, South Beach, and Atkins diets are some of the most popular of these, often referred to as ketogenic or "keto" diets. But a true ketogenic diet differs from these other approaches - while they may focus primarily on protein, with a keto diet, the emphasis is on fat, which can provide up to 90% of the calories. It certainly is a diet you want to try with careful consideration.
1. What is the Keto Diet?
The ketogenic diet is an alternative dietary approach that seeks to induce ketosis in the body. This metabolic state occurs when insulin levels are low, and the body is forced to rely on fat reserves to produce energy. The diet limits carbohydrate intake to less than 20-50 grams daily while moderating protein intake to not interfere with ketosis. This specific approach aims to ensure that the body relies on fat as the primary source of fuel and not glucose.
Once the body enters the ketosis metabolic state, it will burn fat as its primary fuel source instead of carbohydrates. This diet is also believed to have several health benefits, such as helping with weight loss and controlling blood sugar. However, it is essential to note that the keto diet is restrictive and requires close monitoring to ensure health and safety.
2. Benefits of the Keto Diet
The keto diet is a very low-carb, high-fat diet that has been shown to have many health benefits. It has been used to treat epilepsy, reduce blood pressure, improve cholesterol levels, and more. But beyond its medical uses, the keto diet can also be used for achieving better fitness. The diet's high-fat content helps your body use fat for fuel more efficiently, meaning you'll have more energy for your workouts.
Not all types of fat in the body are the same; where it is stored can determine its impact on health and the potential for developing diseases. The two primary kinds are subcutaneous fat, found underneath the skin, and visceral fat, which builds up in the abdominal area. Visceral fat tends to gather around the organs, and excess can lead to inflammation and insulin resistance, which are common in the Western world. Low-carb diets successfully reduce this harmful abdominal fat, with a more significant percentage of the fat lost from these diets coming from the abdominal area. In the long term, this can lead to a reduced risk of heart disease and type 2 diabetes.
For those with diabetes or insulin resistance, a low-carb or ketogenic diet may be beneficial. Evidence has shown that significantly reducing carbohydrate intake can substantially decrease blood sugar and insulin levels. In many cases, individuals with type 2 diabetes can reduce or stop taking glucose-lowering medications within six months. Therefore, it is essential to discuss with your doctor any changes to dietary carbohydrate intake before making a change, as blood sugar medications may need to be adjusted to avoid hypoglycemia.
3. Potential Risks of the Keto Diet
The ketogenic diet has been linked to many potential health risks. These include an increased risk of kidney stones, constipation, reduced bone density, and increased risk of heart disease due to the high fat content of the diet. Long-term use of the ketogenic diet has also been associated with an increased risk of nutrient deficiencies, such as calcium and Vitamin D.
Adopting the keto diet can significantly change your body, as carb intake is severely limited. This transition can cause what is referred to as 'keto flu,' which includes symptoms like headaches, dizziness, fatigue, nausea, and constipation. These are often due to dehydration and electrolyte imbalances during the body's adjustment period. While this typically passes within a few weeks, it is important to remain mindful of these symptoms and to ensure you are drinking plenty of fluids and consuming foods rich in sodium, potassium, and other electrolytes.
4. Foods to Eat on the Keto Diet
The keto diet is popular for those wanting to get fit and healthy. This diet is based on a high-fat, low-carb diet, which helps reduce inflammation, energy levels, and body fat.
When it comes to foods to eat on the keto diet, there are many options. Here are four of the most popular choices to include in a ketogenic diet:
1. Healthy fats: Healthy fats, such as olive oil, avocados, and coconut oil, provide the body with essential fatty acids while helping suppress hunger.
2. Vegetables: Low-carb vegetables, such as spinach, kale, and broccoli, are high in nutrients and calories, making them a great addition to any keto meal plan.
3. High-quality proteins: High-quality proteins, such as grass-fed beef, wild-caught fish, and organic poultry, provide the body with essential amino acids and help to keep us feeling full.
4. Nuts and seeds: Nuts and seeds are a great source of healthy fats, fiber, and essential vitamins and minerals. They are also low in carbohydrates, making them
5. Tips for Adopting the Keto Diet
The ketogenic diet is one way to improve your fitness and lose weight, but it cannot be easy to adopt. Here are five tips to help you make the transition and stay on track:
1. Start slow. Don't jump in and try to eliminate carbs from your diet all at once completely. Instead, start by reducing your carb intake gradually over a while.
2. Increase your fat intake. The keto diet requires a high fat intake to keep your body in ketosis. Replace some of the carbs you're cutting out with healthy fats such as avocado, coconut, and olive oil.
3. Track your progress. Use an app or website to help you keep track of your macros and your progress. This will help you stay on track and help you to make adjustments if needed.
4. Incorporate exercise. The keto diet is not a replacement for physical activity. Exercise can help speed up weight loss and increase your energy levels. This will also help maintain muscle mass to ensure you lose body fat.
5. Get support. Make sure you have the permission of family and friends. They can help keep you motivated and provide encouragement when you're feeling discouraged.
Should I work out the first week of keto?
In short, take a break if you are currently engaging in regular exercise or a programmed routine. It will allow your body time to transition to another primary fuel source (carbohydrates to fat). However, if you are determined to continue your training, consider a deload week or working out with a partner to ensure your safety and avoid potential injury.
If you are inactive or getting less than 30 minutes of light to moderate exercise a day, here are two choices to help speed up the transition to ketosis: remain idle during this period, as your energy levels may be lower, or you can take brisk walks for between 30-60 minutes per day. Either choice is acceptable.
The ketogenic diet is one of many choices someone can use to improve physical performance and overall health. For example, it can help reduce inflammation, optimize metabolism, and provide an alternative energy source. In addition, its high-fat, low-carb ratio benefits those who have tried other conventional means to lose weight.
