Keto Diet

The ketogenic diet drastically reduces carbohydrate intake and replaces it with fat, leading to a metabolic state called ketosis. In ketosis, the body becomes highly efficient at burning fat for energy and producing ketones in the liver, which can supply energy for the brain. This diet typically involves consuming 70-80% of calories from fat, moderate protein, and very low carbs. Originally developed to treat epilepsy, the keto diet has gained popularity for weight loss and potential cognitive and metabolic benefits. It requires careful planning to maintain the correct macronutrient ratios and avoid nutrient deficiencies. Many people experience rapid initial weight loss due to water loss and reduced appetite. However, the diet can be restrictive and may cause side effects like the 'keto flu' during adaptation. Long-term effects are still being studied, but many find it effective for short to medium-term weight management.

By drastically reducing carbohydrate intake, the body depletes its glycogen stores and begins to break down fat into ketones, which serve as an alternative fuel source. This metabolic shift can improve fat burning and reduce hunger. The high fat intake also helps maintain energy and satiety. Maintaining ketosis requires strict adherence to macronutrient ratios, typically under 20-50 grams of carbs per day. Protein is kept moderate to prevent gluconeogenesis, which can raise blood sugar and disrupt ketosis.
