The keto diet is one of the most popular and effective ways to lose weight, improve health, and boost energy. But what exactly is the keto diet, and how does it work? This guide will explain the basics of the keto diet, its benefits, challenges, and tips for getting started.
Introduction to Keto Diet
The keto diet is a high-fat, moderate-protein, and low-carb diet that aims to put your body into a metabolic state called ketosis. Ketosis is when your body burns fat instead of glucose (sugar) for energy. This can result in weight loss, lower blood sugar levels, reduced inflammation, and improved brain function.
However, the keto diet is only for some. It requires careful planning, monitoring, and adaptation. It can also cause side effects like keto flu, nutrient deficiencies, and increased cholesterol levels. Therefore, you must consult your doctor before starting a keto diet.
Understanding the Basics: High Fat, Moderate Protein, Low Carb Diet
The keto diet is based on three main principles:
- High fat intake: Fat is the keto diet's primary source of calories and energy. It would help if you aimed to get about 60% of your calories from fat sources such as butter, coconut oil, olive oil, avocado, nuts, seeds, cheese, and fatty meats.
- Moderate protein intake: Protein is essential for building and maintaining muscle mass and other tissues. It would help if you aimed to get about 35% of your calories from protein sources such as eggs, fish, poultry, meat, and tofu.
- Low carb intake: Carbs are your body's primary glucose source. When you limit your carb intake to about 5% of your calories (or less than 50 grams per day), your body will switch from glucose to ketones (produced from fat) for energy. This will trigger ketosis and enhance fat burning.
Planning Your Keto Diet: A Step-by-step Guide
To start a keto diet, you need to plan and follow some simple steps:
- Calculate your macros: Macros are the macronutrients (fat, protein, and carbs) you need to consume in a specific ratio to achieve ketosis. You can use online calculators or apps to estimate your macros based on age, weight, height, activity level, and goals.
- Choose your keto-friendly foods: Keto-friendly foods are those that are low in carbs and high in fat and protein. Some examples are meat, fish, eggs, cheese, butter, cream, nuts, seeds, avocados, olives, coconut oil, olive oil, leafy greens, broccoli, cauliflower, zucchini, berries, and dark chocolate. You should avoid foods high in carbs and sugar, such as bread, pasta, rice, potatoes, corn, beans, legumes, fruits (except berries), milk (except cream), honey, and maple syrup.
- Plan your meals: You can use online tools or apps to create your meal plans or follow existing ones. It would help if you aimed to have three meals a day with some snacks in between. It would help to drink plenty of water and electrolytes (such as sodium, potassium and magnesium) to stay hydrated and prevent dehydration.
- Track your progress: You can use ketone strips or meters to measure your ketone levels in your urine or blood. This will help you monitor if you are in ketosis or not. You can also use scales or tape to track your weight loss or body measurements. You should also pay attention to how you feel physically and mentally on the keto diet.
The Keto Diet and Type 2 Diabetes
Type 2 diabetes is when your body becomes resistant to insulin and cannot regulate your blood sugar levels properly. This can lead to high blood sugar levels, which can cause various complications such as nerve damage, kidney damage, eye damage, and heart disease.
The keto diet can help manage type 2 diabetes by:
- Lowering your blood sugar levels: The low-carb intake on the keto diet can reduce the amount of glucose in your bloodstream and prevent spikes and crashes. This can improve your blood sugar control and reduce your need for medication.
- Improving your insulin sensitivity: The high fat intake on the keto diet can increase the production of ketones, which are molecules that can act as alternative fuel for your cells. Ketones can bypass insulin resistance and enter your cells without needing insulin. This can improve your insulin sensitivity and lower your insulin levels.
- Reducing your inflammation: The keto diet can reduce inflammation in your body by lowering the levels of inflammatory cytokines, which are substances that trigger inflammation. Inflammation is a significant factor in type 2 diabetes and its complications.
Long-Term Effects of a Ketogenic Diet
The keto diet is not only a short-term solution for weight loss or health improvement. It can also have long-term effects on your body and health. Some of these effects are:
- Improved cardiovascular health: The keto diet can lower blood pressure, cholesterol, triglycerides, and inflammation, all risk factors for heart disease and stroke.
- Enhanced cognitive function: The keto diet can improve your brain function by providing ketones as an alternative fuel for your brain cells. Ketones can also protect your brain from oxidative stress, inflammation, and neurodegeneration.
- Reduced risk of cancer: The keto diet can reduce cancer risk by starving cancer cells of glucose, their preferred fuel source. The keto diet can also activate autophagy when your cells recycle damaged or unwanted parts.
- Increased longevity: The keto diet can extend your lifespan by activating genes involved in anti-ageing and longevity. The keto diet can also delay the onset of age-related diseases such as Alzheimer's, Parkinson's, and diabetes.
- Improved hormonal balance: The keto diet can balance your hormones by regulating your insulin, cortisol, and leptin levels. Insulin is the hormone that controls your blood sugar levels, cortisol is the hormone that controls your stress response, and leptin is the hormone that controls your appetite and metabolism.
However, the keto diet is not without risks and considerations. Some of these are:
- Ketoacidosis: Ketoacidosis is a serious condition where your blood becomes too acidic due to the accumulation of ketones. Ketoacidosis can cause nausea, vomiting, abdominal pain, confusion, and coma. Ketoacidosis is more common in people with type 1 diabetes or alcoholism but can also occur in people with type 2 diabetes or other medical conditions. You should monitor your ketone levels and seek medical attention if you experience any symptoms of ketoacidosis.
- Nutrient deficiencies: The keto diet can cause nutrient deficiencies due to the restriction of certain foods that are rich in vitamins, minerals, antioxidants, and fibre. You should supplement your diet with multivitamins, minerals, omega-3 fatty acids, and probiotics to prevent or correct deficiencies.
- Kidney stones: The keto diet can increase the risk of kidney stones due to the increased excretion of calcium and uric acid in your urine. You should drink plenty of water and add lemon juice or apple cider vinegar to your drinks or foods to prevent or dissolve kidney stones.
- Constipation: The keto diet can cause constipation due to a lack of fibre. You should eat more fibre-rich foods such as leafy greens, nuts, seeds, flaxseeds, chia seeds, psyllium husk, or coconut flour to improve your bowel movements.
- Cholesterol levels: The keto diet can affect your cholesterol levels differently depending on your response. Some people may experience a decrease in their LDL (bad) cholesterol and an increase in their HDL (good) cholesterol, while others may experience the opposite. You should check your cholesterol levels regularly and adjust your fat intake accordingly.
