The ketogenic diet or Keto is often compared to a low carb approach but there are key differences. If you are deciding between the two it is important to understand where they align and where they differ to help you choose the method that best suits your health goals and lifestyle.

Ketogenic Diet

The ketogenic, or “keto”, diet is a nutritional approach that prioritises the intake of healthy fats—such as avocado, olive oil, seeds, and oily fish rich in omega-3 fatty acids—while significantly reducing carbohydrate consumption. This shift encourages the body to enter a state known as ketosis, in which it burns fat instead of carbohydrates as its primary source of energy.

By relying on fat for fuel, the body becomes more efficient at breaking down stored fat, which can lead to rapid weight loss. At the same time, blood sugar levels tend to drop, as insulin secretion is reduced—an effect that may be particularly beneficial for those with type 2 diabetes or individuals seeking noticeable results in a relatively short time.

Advantages of the Ketogenic Diet:

• Promotes rapid weight loss, as the body more readily burns fat stores.
• Helps regulate blood sugar levels, supporting a healthier metabolic system.
• No need to count calories or go hungry as long as the focus remains on consuming the right kinds of healthy fats.

In summary, the keto diet offers a compelling route to improved metabolic health and weight control, provided it is followed mindfully and with a balanced intake of quality fats.

Important Considerations and Precautions

• Possible bad breath: A common side effect of high-fat diets is unpleasant breath. This occurs as the body releases acetone, a byproduct of fat metabolism through the breath.
• Choose healthy fats wisely: It’s crucial to consume beneficial fats in appropriate amounts. Overindulging in unhealthy fats may lead to long-term health complications.
• ‘Keto flu’ symptoms: Before the body fully adapts to ketosis, some individuals may experience what’s known as the ‘keto flu’, with symptoms such as stomach discomfort, fatigue, dizziness, or mood swings. These typically subside as the body adjusts, but if symptoms become severe, it’s advisable to stop the diet and consult a medical professional.
• Not suitable for everyone: The ketogenic diet can be risky for individuals with pre-existing health conditions, especially those with issues related to the pancreas, thyroid, or for those who are pregnant.
• Unsustainable for long-term health: While effective for short-term weight loss, the keto diet is generally not recommended as a long-term approach to weight management or overall wellness.

Low Carbohydrate Diet (Low Carb)

The Low Carb Diet involves reducing daily carbohydrate intake, typically to around 50 to 100 grams per day, while placing greater emphasis on protein-rich foods. When the body receives less starch and sugar, it shifts towards using fat and protein as its main sources of energy. This adjustment can lead to more effective weight management and may contribute to overall improvements in health.

Foods that are high in carbohydrates such as refined grains, sugary beverages, high-sugar fruits, and processed foods are usually limited or avoided.

Key Benefits of a Low Carb Diet

• Helps regulate weight and blood sugar levels
• Encourages the body to use protein to build and maintain muscle

Important Considerations

• Not recommended for long-term health maintenance, as it may lead to an acidic imbalance in the blood
• May result in nutritional deficiencies and a lack of dietary fibre, potentially causing digestive issues
• May not be appropriate for individuals with pre-existing health conditions

Whether you choose to follow a Low Carb or Ketogenic diet, the most important consideration is ensuring that the approach is safe and suitable for your individual needs. Nutrition is highly personal, and what works for one person may not work for another. It is always advisable to consult a medical professional before making significant changes to your diet, to determine which method is best aligned with your health and lifestyle goals.
