What is the Keto Diet?

• A high fat, moderate protein, ultra-low carbohydrate diet.
• Caloric distribution: 70% fat, 20% protein, no more than 10% carbohydrates.
• Puts the body into ketosis: the state where the body uses fat instead of carbohydrates for energy.

Foods to Eat on the Keto Diet

• High-fat proteins: red meat, pork, chicken, bacon, sausage.
• Nuts and seeds.
• Low-carb vegetables: spinach, asparagus, onion, peppers.
• Low-carb fruits: berries.
• Oils and fats: avocado oil, olive oil, butter, coconut oil.

Foods to Avoid on the Keto Diet

• Starchy and sweet foods: pasta, rice, brownies, ice cream.

Meal Ideas for the Keto Diet

• Breakfast: Cheesy omelettes with non-starchy vegetables, avocado as a topping.
• Lunch/Dinner: Chicken or shrimp salad with full-fat mayonnaise or Greek yogurt, greens dressed with olive oil.
• Snacks: Berries with full-fat Greek yogurt, nuts.
• Avoid processed meats despite their ease of fitting into the diet.

Benefits of the Keto Diet

• Weight Loss: Naturally lower calorie intake due to filling high-fat foods.
• Simplicity: Easier meal planning without calorie counting as long as carb intake is controlled.
• Neurological Benefits: Originated in the 1920s to help control epilepsy; potential benefits for Alzheimer's, MS, and Parkinson's, though more research is needed.

Downsides of the Keto Diet

• Nutritional Risks: Potential increased risk of heart disease depending on food choices.
• Keto Flu: Flu-like symptoms (headaches, nausea, fatigue) when entering ketosis. Mitigated by proper hydration and electrolyte intake.
• Not suitable for everyone: Pregnant/nursing women, history of eating disorders, risk of chronic conditions like heart disease, and possibly diabetes.

Considerations Before Starting Keto

• Consult Professionals: Speak with a doctor or dietitian for personalized advice.
