Protein-Based Diet
Keto Diet
The ketogenic diet is a high-fat, low-carbohydrate eating plan designed to shift your body's metabolism from burning glucose to burning fat. By drastically reducing carbohydrate intake and replacing it with healthy fats, your body enters a metabolic state called ketosis — where it becomes incredibly efficient at converting fat into energy.
Mechanism
How the keto diet works
The keto diet works by fundamentally changing how your body produces energy. Under normal conditions, your body breaks down carbohydrates into glucose, which serves as its primary fuel. When carbohydrates are restricted to under 50 grams per day, this glucose-based metabolism shifts.
Once glycogen reserves are depleted, the liver begins converting fat into ketone bodies. These ketones become the body's new energy source — fueling the brain, muscles, and organs from stored fat instead of dietary carbohydrates. This metabolic state is called ketosis, and it usually takes 2–4 days of sustained low-carb intake to reach.
-
Restrict Carbs
Carbohydrate intake is drastically reduced to under 50g per day, removing the body's primary energy source.
-
Deplete Glycogen
With no incoming carbs, the body exhausts its glycogen reserves stored in the liver and muscles.
-
Produce Ketones
The liver converts fatty acids into ketone bodies — an efficient alternative fuel for the brain and body.
-
Burn Fat for Fuel
The body becomes remarkably efficient at burning stored fat, providing sustained energy and promoting weight loss.

History
History
- 5th Century BC
First Observations
Ancient Greek physicians, including Hippocrates, first document that complete fasting can manage epilepsy by fundamentally changing the body's metabolism.
- 1921
The "Keto" Term Coined
Dr. Russell Wilder at the Mayo Clinic coins the term "ketogenic diet", designing a high-fat, low-carb plan to mimic the metabolic benefits of fasting.
- Late 20th Century
Modern Resurgence
The Charlie Foundation is established in 1994 after Charlie Abrahams achieves seizure freedom through the diet, sparking global research and media attention.
- 21st Century
Metabolic Health Frontier
Modern research expands the diet's use beyond epilepsy to treat obesity and type 2 diabetes, focusing on insulin sensitivity, inflammation reduction, and neuroprotective benefits.
