Understanding the Ketogenic Diet
One of the most popular diets for promoting weight loss and improving overall health in older adults is the ketogenic diet. This high-fat, low-carbohydrate eating plan has gained popularity for its potential to improve heart health and other aspects of wellness.
Principles of Ketosis
Ketogenic diets are designed to shift the body's metabolism away from relying on carbohydrates for energy and instead towards burning fat for fuel. This shift results in the production of ketones, which are natural by-products of burning fat. When the body reaches a state of ketosis, it becomes more efficient at burning fat for energy, which can lead to weight loss and improved heart health.
Macronutrient Distribution and Food Types
- Fat: The majority of calories (70-80%) in a ketogenic diet come from healthy fats such as avocados, nuts, seeds, and olive oil.
- Protein: Moderate amounts of protein (20-25% of calories) are included in the diet, with a focus on lean sources such as poultry, fish, and tofu.
- Carbohydrates: Carbohydrates are severely restricted, typically making up only 5-10% of total calorie intake. Non-starchy vegetables and small amounts of berries are the primary sources of carbohydrates.
The ketogenic diet emphasizes whole, unprocessed foods that are high in healthy fats and low in carbohydrates. The restriction of carbohydrates forces the body to rely on fat for energy, which can lead to weight loss and improvements in heart health.
