How does the Keto Diet differ from other low-carb diets, such as Atkins or Paleo?

Question in Health and Wellness about Keto Diet published on

The Keto Diet is a specific type of low-carb diet that focuses on consuming high amounts of healthy fats and limiting carbohydrate intake to induce a metabolic state called ketosis, where the body primarily uses fat for fuel. Unlike other low-carb diets like Atkins or Paleo, the Keto Diet emphasizes a very low carbohydrate intake, typically around 20-50 grams per day. Additionally, while both Atkins and the Paleo diet allow higher protein intake, the Keto Diet emphasizes moderate protein consumption to prevent excess gluconeogenesis (the process where protein can be converted into glucose in the body). The main goal of the Keto Diet is to shift the body’s metabolism towards burning fat for energy consistently.

Long answer

The Keto Diet (short for Ketogenic Diet) is a low-carb diet that differs from other popular low-carb diets like Atkins or Paleo in several ways. Firstly, while both Atkins and the Keto Diet are considered low-carb, the Keto Diet focuses on extremely low carbohydrate intake compared to Atkins. On average, individuals following a ketogenic approach usually aim for around 20-50 grams of net carbohydrates per day. This level of restriction helps induce a state called ketosis.

Ketosis is a metabolic state where due to limited carbohydrate availability, the body starts relying primarily on fat for fuel instead of glucose. This occurs because when carbohydrates are scarce, and glycogen stores run out, fatty acids are broken down into ketone bodies in the liver through a process called ketogenesis. These ketone bodies then serve as an alternative energy source for the brain and muscles.

Contrastingly, Atkins promotes different phases with varying levels of carbohydrate restrictions but comparatively allows wider flexibility regarding reintroducing carbs as individuals progress through these phases. It aims to find an individual’s personal carbohydrate tolerance level at which they can maintain weight loss without gaining more weight back.

Another difference lies in their approach towards protein consumption. While both Atkins and the Keto Diet include higher protein intake, the Keto Diet emphasizes moderate protein consumption. This is because excessive protein consumption can lead to gluconeogenesis, a process where excess protein converts into glucose in the body, potentially interfering with ketosis. On the other hand, Atkins allows for higher protein intake.

Regarding nutrient quality, the Paleo Diet focuses on consuming whole and unprocessed foods that are believed to have been available during the Paleolithic era. It restricts grains, legumes, processed foods, and certain dairy products while emphasizing lean meats, fish, eggs, nuts, seeds, fruits, and vegetables. In comparison, while the Keto Diet does not specifically restrict any food groups based on their processing or evolutionary history like Paleo does, it generally encourages consuming healthy fats from sources like avocados, coconut oil, olive oil, nuts and seeds.

In summary, the primary difference between the Keto Diet and other low-carb diets such as Atkins or Paleo lies in their level of carbohydrate restriction and approach towards protein consumption. The Keto Diet aims for an extremely low carbohydrate intake to induce and maintain ketosis consistently while emphasizing moderate protein consumption to prevent excess gluconeogenesis. Conversely, Atkins and Paleo diets allow for more flexibility in carbohydrate intake levels and have varying approaches towards protein intake and nutrient quality based on individual preferences or historical dietary patterns.
