A low-carb diet is an eating plan that restricts carbohydrate intake, typically to less than 130 grams per day. This approach aims to force the body to burn fat for energy instead of relying on glucose from carbohydrates.
Key Characteristics / Core Concepts
- Reduced carbohydrate consumption: Significantly lower than typical Western diets.
- Increased fat intake: Often becomes the primary energy source.
- Moderate protein intake: Helps maintain muscle mass and satiety.
- Focus on whole, unprocessed foods: Emphasizes nutrient density.
- Potential weight loss: A common goal for many adopting this diet.
How It Works / Its Function
By limiting carbohydrates, the body enters a metabolic state called ketosis. In ketosis, the liver converts fat into ketones, which the body uses as fuel. This process can lead to weight loss, as the body taps into stored fat reserves.
Examples
- Ketogenic diet (very low carb, high fat): Restricts carbs to 20-50 grams per day.
- Atkins diet: Similar to keto, focusing on gradual carb reintroduction.
- Paleo diet: Emphasizes whole foods and naturally excludes many refined carbs.
Why is it Important? / Significance
Low-carb diets are often used for weight management and have shown effectiveness in helping individuals lose weight and improve metabolic markers. However, it’s crucial to consult a healthcare professional before making significant dietary changes.
