Difference between Keto and Low Carb Diet

In recent years, various dietary approaches have gained popularity for their potential health benefits and weight management effects. Two commonly discussed strategies are the ketogenic diet (Keto) and low-carbohydrate diet (Low Carb). While they share some similarities, there are key differences that distinguish these dietary approaches.

What is Keto?

The ketogenic diet is a high-fat, low-carbohydrate diet designed to induce a state of ketosis in the body. Ketosis occurs when the body shifts from using glucose as its primary energy source to burning fat for fuel. In a typical ketogenic diet, carbohydrates are severely restricted, and fats make up the majority of caloric intake. Moderate protein consumption is also encouraged.

What is a Low Carb Diet?

A low-carbohydrate diet, as the name suggests, is characterized by a reduction in the intake of carbohydrates. Unlike the strict carbohydrate restriction in keto, a low-carb diet may not necessarily focus on high fat intake. It involves choosing foods that are lower in carbohydrates and higher in protein and/or healthy fats. The goal is to manage blood sugar levels and promote weight loss.

Difference Between Keto and Low Carb Diet:

  1. Carbohydrate Intake:
    • Keto: Very low carbohydrate intake, typically around 5-10% of total daily calories.
    • Low Carb: Carbohydrate intake is reduced but may vary, with a broader range, often around 20-40% of total daily calories.
  2. Fat Intake:
    • Keto: High fat intake, usually comprising 70-75% of total daily calories.
    • Low Carb: Fat intake can vary, but it is generally lower than in the ketogenic diet.
  3. Protein Intake:
    • Keto: Moderate protein intake, making up about 15-20% of total daily calories.
    • Low Carb: Protein intake can vary, but it is often higher than in the ketogenic diet.
  4. Nutritional Ketosis:
    • Keto: The primary goal is to achieve and maintain a state of nutritional ketosis.
    • Low Carb: Nutritional ketosis is not necessarily the primary focus; the emphasis is on reducing overall carb intake.

Comparison Chart:

Aspect Keto Low Carb
Carbohydrate Intake Very low (5-10% of calories) Low to moderate (20-40% of calories)
Fat Intake High (70-75% of calories) Moderate to high
Protein Intake Moderate (15-20% of calories) Moderate to high
Nutritional Ketosis Primary goal Not necessarily the primary focus
Sustainability Requires strict adherence May be more flexible
Health Focus Weight loss, epilepsy treatment, metabolic health Weight loss, blood sugar management


Both the ketogenic diet and low-carbohydrate diet offer viable approaches to weight management and overall health. The choice between them often depends on individual preferences, health goals, and the body’s response to different macronutrient compositions. Consulting with a healthcare professional or a registered dietitian is advisable before embarking on any significant dietary changes to ensure that the chosen approach aligns with individual health needs and goals. As with any diet, sustainable and healthy habits should be prioritized for long-term well-being.
