The ketogenic, or keto, diet has gained significant attention for its unique approach to weight loss and health. Unlike other diets that focus on calorie restriction, the Keto Dietchanges how your body sources energy by shifting its fuel source from carbohydrates to fat. This guide explains how the keto diet works and what foods to include.
How It Works
The main goal of the keto diet is to get your body into a metabolic state called ketosis. Normally, your body uses glucose (sugar) from carbohydrates for energy. When you dramatically reduce your carb intake and replace it with fat, your body starts looking for an alternative fuel.
It turns to the fat you eat and your stored body fat, breaking it down into molecules called ketones. These ketones then become your body’s primary energy source. To achieve and maintain ketosis, a typical keto diet involves getting about 70-80% of your daily calories from fat, 10-20% from protein, and only 5-10% from carbohydrates. This strict limit on carbs is essential for the diet’s effectiveness.
What to Eat
Navigating a keto-friendly menu is simpler than it might seem. The focus is on whole, unprocessed foods that are high in healthy fats and low in carbohydrates.
Foods to Include:
• Healthy Fats: Avocado, olive oil, coconut oil, butter, and nuts.
• Protein: Fatty fish like salmon, meat (beef, pork, poultry), and eggs.
• Low-Carb Vegetables: Leafy greens like spinach and kale, along with broccoli, cauliflower, and zucchini.
• Dairy: Full-fat cheese, cream, and Greek yogurt.
Foods to Avoid:
• Sugary Foods: Soda, fruit juice, candy, and desserts.
• Grains: Wheat-based products, rice, pasta, and cereal.
• Most Fruits: High-sugar fruits like bananas and grapes (small portions of berries are okay).
• Starchy Vegetables: Potatoes, sweet potatoes, and corn.
Is the keto diet safe for everyone?
The keto diet may not be suitable for individuals with certain medical conditions, such as kidney disease or pancreatitis. It’s always best to consult with a healthcare provider before starting.
What is the “keto flu”?
The “keto flu” refers to a group of symptoms like headache and fatigue that can occur as your body adjusts to using fat for energy instead of carbs. These symptoms are usually temporary and can be managed by staying hydrated.
