Understanding Keto Diet Fundamentals
The ketogenic diet is a low-carb, high-fat eating plan designed to shift the body’s metabolism. It aims to induce a state of ketosis, where fat becomes the primary fuel source instead of carbohydrates.
Defining Ketogenic Diet and Ketosis
A ketogenic diet typically limits carbohydrate intake to 20-50 grams per day. This restriction forces the body to burn fat for energy, producing ketones.
Ketosis occurs when blood ketone levels rise above 0.5 mmol/L. This metabolic state can lead to rapid fat loss and improved energy levels.
The diet consists mainly of fats (70-80% of calories), moderate protein (20-25%), and very low carbohydrates (5-10%).
Foods allowed on keto include:
- Meats and fatty fish
- Eggs
- High-fat dairy
- Nuts and seeds
- Low-carb vegetables
Benefits and Challenges of a High-Fat Diet
Potential benefits of a ketogenic diet include:
- Weight loss
- Improved insulin sensitivity
- Reduced inflammation
- Enhanced mental clarity
Some people report increased energy and reduced appetite on keto.
Challenges of the diet may include:
- Initial “keto flu” symptoms
- Difficulty adhering to strict carb limits
- Potential nutrient deficiencies
Proper electrolyte balance is crucial on keto. Sodium, potassium, and magnesium levels need careful monitoring.
Transitioning to a high-fat diet can be challenging for some. It often requires significant changes to eating habits and food choices.
