Low Carb High Fat Diet: What It Is, Benefits & Foods List In 2023

Recently, the low-carb, high-fat diet, or LCHF diet, has gained significant popularity. The LCHF diet plan is a nutritional approach focusing on reducing carbohydrate intake while increasing healthy fat consumption. 

This special diet has proven beneficial for various groups, including those looking to lose weight, manage diabetes, and prevent other chronic conditions. This low-carb diet offers a different perspective on carbs, protein, and fat distribution. It shows that reducing carb intake and embracing healthy fats helps to achieve health and lifestyle goals. The problem with this diet is that it lacks^[1] clear macronutrient goals. 

Below, we will explore the numerous benefits of the LCHF diet, discuss delicious meal ideas, and provide tips on effectively implementing this lifestyle change. You will also get a comprehensive list of foods to eat and avoid and tips to help you sustain the diet.

What Is The Low Carb, High Fat Diet?

The low-carb, high-fat diet is a nutritional approach focusing on reducing carbohydrate intake and replacing it with healthy fats. Originating in Sweden, this diet can be effective in promoting weight loss, managing diabetes, and improving other health conditions^[2] like cardiovascular disease.

In a typical LCHF diet, a person obtains less than 45% of their daily calories from carbohydrates, while fat intake ranges from moderate to high. Simply put, you add fats to a diet. Also, the diet includes proteins, vitamins, and minerals. 

Moreover, the LCHF diet promotes satiety due to the consumption of healthy fats, which can help reduce overall calorie intake and support weight loss. The LCHF diet shares similarities with the Atkins and ketogenic diets — they all fall under the same umbrella. They all involve reducing carbohydrate intake and increasing fat consumption, but Atkins and ketogenic diets usually require a higher level of carb restriction.

Who Is This Diet For?

The high-fat, low-carb diet^[3] is suitable for a variety of individuals. It is a good option if you want to be proactive with your health. However, it is often recommended to people who have struggled with traditional low-fat diets.

It also works for people who are looking to manage specific health conditions. Some specific conditions that may benefit from the LCHF diet include:

1. Diabetes.^[4]
2. Neurological diseases.^[5]
3. Heart diseases.^[6]
4. PCOS.^[7]

While adequate research shows that the LCHF diet can benefit these conditions, it’s essential to consult a healthcare professional before making significant dietary changes. Individual needs and health conditions may vary.

Benefits Of Low-Carb High-Fat Diets

Low-carb, high-fat diets have numerous potential health benefits and effectiveness for weight loss. Some of these high-fat diet benefits include:

• Weight Loss: One of the primary reasons people adopt an LCHF diet is for weight loss.^[8] When you reduce carbohydrate intake and increase healthy fats, the body enters a state of ketosis. This encourages the body to burn stored fat for energy instead of glucose.
• Improved Blood Sugar Control: Another high-fat diet benefit is that it can help regulate blood sugar levels and improve insulin sensitivity. This is particularly beneficial for people with type 2 diabetes^[9] or those at risk of developing the condition.
• Increased Satiety: High-fat foods are often more satiating than high-carb foods, helping to reduce hunger and cravings. This can lead to a reduced calorie intake, making it easier to stick to a healthy diet.
• Enhanced Mental Clarity: Many people who follow an LCHF diet report increased mental clarity and focus.^[10] This may be due to the brain’s ability to efficiently use ketones as a fuel source when glucose is limited. The LCHF diet also contains specialized vitamins that help improve brain function.
• Improved Energy Levels: Once the body adapts to using fat for fuel, energy levels may become more stable and consistent throughout the day without the energy crashes often associated with high-carb diets. 
• Better Heart Health: Although an LCHF diet is high in fat, it often emphasizes healthy fats, such as avocados, nuts, and olive oil. These fats can help improve cholesterol levels and support overall heart health.
