What is the Keto Diet? Your Complete Guide to Ketogenic Living
The ketogenic diet (keto) is a revolutionary approach to nutrition that transforms your body into a fat-burning powerhouse. This comprehensive guide will walk you through everything you need to know about the keto diet and how it can help you achieve your health goals.
The standard keto macro ratio often recommended is:
70-80% fat: This provides your body with a readily available fuel source and promotes ketosis, the metabolic state where ketones replace glucose as the primary energy source.
5-10% carbohydrates: Limiting carbs keeps the body in ketosis and minimizes blood sugar fluctuations. Net carbs (total carbs minus fiber) are usually considered.
15-20% protein: This is essential for muscle maintenance, tissue repair, and various bodily functions.
Understanding the Science Behind Keto
The ketogenic diet fundamentally changes how your body produces energy. By drastically reducing carbohydrate intake to under 50 grams per day and increasing healthy fat consumption, your body enters a metabolic state called ketosis. During ketosis, your body:
- Switches from using glucose as its primary fuel source to burning fat
- Produces ketones in the liver, which provide energy for your brain
- Becomes more efficient at utilizing stored body fat for energy
- Maintains more stable blood sugar levels throughout the day
