The Keto Diet Explained

The Ketogenic diet is very low in carbohydrates and high in fat. The diet typically excludes most fruits, starchy vegetables and grains. 

The diet is clinically used to treat children with drug-resistant epilepsy under management of specialist dietitians.

In recent years the Keto style diet has grown in popularity for its perceived ability to assist weight loss. The process is thought to cause the body to break down fat into molecules called ketones to use as the main source as energy rather than glucose from carbohydrates (the body’s preferred fuel source). This metabolic state is best known as ketosis.

There are several reasons why you may want to think twice before adopting this diet.

Keto is NOT Sustainable for Long Term Health

Studies have shown a reduction in weight on the ketogenic diet, however this weight reduction is not usually sustained long term. 

Here are some of the many reasons we wouldn’t recommend Keto for long term health:

  • Your body needs Carbohydrates: Not only are they required for energy but they are essential for several hormonal processes. 
  • Research has found that people who followed a low carb/high fat diet had a 44% increase in low-density lipoprotein cholesterol (the ‘bad’ cholesterol). Saturated fats increase our risk of high cholesterol, heart disease and stroke, therefore should be consumed in moderation as part of a balanced diet. 
  • The Keto diet excludes many foods rich in essential vitamins and minerals.
  • The Keto diet also lacks Fibre. The benefits of fibre include improving blood sugar levels, digestion and reducing the likelihood of constipation. In the UK most people do not consume enough fibre.


Overall, yes for many people the Keto diet can be an effective tool for weight loss, however it is a restrictive diet that is high in saturated fat and low in fibre. Meaning it doesn’t observe the reccomended nutritional guidelines.
