The ketogenic (keto) diet is a low-carb, high-fat eating strategy designed to shift the body into a state called ketosis, where fat becomes the primary source of fuel instead of carbohydrates. Originally developed to treat epilepsy, keto has since gone mainstream as a powerful tool for weight loss, mental clarity, and blood sugar stability.
How the Keto Diet Works
In a typical diet, carbohydrates supply most of your energy. When carbs are drastically reduced (usually to 20–50 grams per day), the body enters ketosis. In this state, the liver converts fat into ketones, an efficient fuel source for both the brain and body.
Core Macronutrient Breakdown
- Fat: 70–75%
- Protein: 20–25%
- Carbohydrates: 5–10%
This macronutrient shift encourages fat burning and minimizes insulin spikes.
Health Benefits of Keto
- Fat loss: Many experience rapid weight reduction, especially visceral fat.
- Mental focus: Ketones are a clean brain fuel, reducing energy crashes.
- Blood sugar control: Helps manage type 2 diabetes and insulin resistance.
- Appetite suppression: Fat and protein increase satiety and reduce cravings.
Considerations & Drawbacks
- Keto flu: Fatigue, headaches, and nausea may appear during the transition.
- Electrolyte imbalances: Supplementing sodium, magnesium, and potassium is essential.
- Long-term sustainability: It requires planning and discipline, especially socially.
Always consult a healthcare professional before starting any restrictive diet.
