The Ketogenic (or keto) diet has gained popularity being hailed as the next big thing for weight loss. It follows the same low-carb trend as the famed Atkins and South Beach diet, however, the Keto diet was initially designed as early as the 1920s for the treatment of refractory epilepsy.
It is fundamentally a high-fat diet that restricts carbohydrate intake below the recommended daily intake. Typically in low-carb diets, fat comprises 70–80%, proteins 10–20 %, and carbs only 5–10 % of the calories.
How Does It Work?
The radical reduction in carbohydrate intake results in the production of ketones in the liver, which switches the body’s fuel source from glucose to fatty acids. This shift affects many fundamental biological processes which is thought to underlie the Keto diet’s therapeutic benefit.
What Is the Evidence?
There is some evidence for the Keto diet improves weight loss, however, the diet does not come without risks and can pose health concerns if used on a long-term basis, especially if not guided by a professional. Research shows that those who follow low-carb diets can experience greater weight loss over a six-month period but, after 12 months, there is no significant difference from conventional low-fat, low-calorie diets.
Research has also shown that the Keto diet has been associated with a shift of all that lovely beneficial bacteria in your gut. This is largely because when all the tasty, healthy carbohydrates that is cut out of the Keto diet, it disrupts gut diversity which is vital for gut health.
In addition excluding or limiting major food groups (eg, grains, dairy, and certain fruit and vegetables), means it is much more difficult to obtain all required nutrients, particularly fibre and B vitamins. This may leave gaps of vital nutrients resulting in low energy levels and lethargy.
