Air Fryer Keto Recipes Easy And Delicious

A keto-friendly diet is a high-fat, moderate-protein, low-carbohydrate diet that was originally designed to treat childhood epilepsy.

The diet’s goal is to force the body into ketosis, a state in which it burns fat for energy rather than glucose.

Using this diet you can drastically reduce carbohydrates and substitute healthy fats. This diet typically consists of 70-75% fat, 20-25% protein, and 5-10% carbohydrates.

How Does The Keto Diet Work?

The diet works by drastically reducing carbohydrate intake and increasing healthy fat consumption, causing the body to enter a metabolic state known as ketosis.

The body switches from burning glucose for energy to burning stored fat for fuel in this state. This is due to the liver producing ketones without carbohydrates, which the body uses as an alternative energy source.

The high-fat diet contributes to this metabolic state and provides the body with the energy it requires to function properly. Limiting carbohydrate intake and relying on fat for energy allows the body to burn stored fat, resulting in weight loss.

The diet may provide additional health benefits such as improved insulin sensitivity and reduced inflammation.

What Are Keto Macros And Ratios?

Macronutrients are nutrients that provide energy to the body and are needed in large amounts in the diet.

The typical keto macro ratios are 70-75% fat, 20-25% protein, and 5-10% carbs.

Individual macronutrient requirements can vary depending on factors such as age, gender, weight, and activity level.

Some people may require slightly more or less of each macronutrient to achieve optimal ketogenic diet results.

It is important to consult with a GP about the best macro ratios for your needs.

Macros are the specific fat, protein, and carbohydrate ratios that someone follows on a ketogenic diet, with a typical ratio of 70-75% fat, 20-25% protein, and 5-10% carbs.

Benefits Of Keto Nutrition And Ketosis

Some people have reported these health benefits, but the evidence is limited, and more research is required.

Always consult your GP before starting this diet.

Steps To Keto Success

The following are the steps to success on the ketogenic diet:

Before beginning a ketogenic diet, consult with a doctor or registered dietitian, especially if you have a medical condition.

Determine your daily caloric requirements and macro ratios (fat, protein, carbs) that will put you in ketosis. This diet typically contains 70-75% fat, 20-25% protein, and 5-10% carbohydrates.

Plan and prepare your meals ahead of time, emphasising high-fat, low-carb foods like meat, fish, eggs, dairy products, oils, nuts, and non-starchy vegetables.

Keep track of your food intake and check your ketone levels to ensure you’re in ketosis.

Stay hydrated by drinking plenty of water.

Be aware of hidden carbohydrates in foods and beverages, and limit or avoid processed and high-carb foods.

To support overall health and weight loss, add physical activity and exercise into your daily routine.

Maintain consistency in your diet and lifestyle choices, and make adjustments as needed to stay in ketosis.

Be patient and persistent, as it may take several weeks or months to fully adapt to and reap the benefits of the ketogenic diet.

This makes it easier to maintain the high-fat, low-carb ratio required for a keto diet.

You can enjoy crispy, crunchy, and delicious foods without the added carbohydrates and unhealthy fats often associated with deep-fried foods by using an air fryer, making it great for a keto diet.
