What is it?

The ketogenic diet or keto diet, is a strict low carb high fat diet. The idea is to put the body into a state of ketosis.

Ketosis is a metabolic process where the body uses fat for fuel instead of glucose. This occurs when the body has drained all of its carbohydrate stores – during times of fasting, starvation or when carbohydrate intake is limited. The process involves the breakdown of fats in the liver to produce ketones.

Ketones are an alternative fuel,  which can continue to fuel the brain (the brain can only run on glucose or ketones) and the body.

Essentially, you become an efficient fat burning machine.


The benefits

The keto diet promotes FAT loss.  As mentioned, carbs are so limited that the body is forced to tap into its fat stores for fuel, leading to weight loss. Studies have found that it trumps the low fat diet [1]. Fat increases satiety and you are less likely to feel hungry in between meals.

Also, the low carb intake reduces the production of insulin. When you eat carbs, insulin is constantly being produced. Insulin prevents the breakdown of fats and encourages the conversion of glucose to fat. How-Weight-Loss-Works-02

The nature of this diet is also benefitial for people with Type 2 diabetes, prediabetes or insulin resistance [2]. This is because fat does not impact insulin the same way as carbs and proteins [3]. Low carb intake helps with managing blood sugar levels. Also, weight loss can improve insulin sensitivity.

The keto diet also seems to improve markers associated with other metabolic diseases [4]. Other health related benefits include neurological (Alzheimers, epilepsy, seizures) [5, 6], cancer [7], improves blood lipid profile and reduces inflammatory markers.
In terms of the keto diet for athletic performance, there is limited research. This diet is thought to be suitable for endurance based sports at submaximal effort (such as the marathon or ultramarathon) where high intensity sprints/bursts are not involved [8].
Then again, there are some high performing athletes that can thrive off a keto diet. It all boils down to their unique genetic make up, how well they can tolerate and adapt to the diet.

LOW carb, HIGH fat

There are different degrees of “low carb” within the keto diet.ketogenic-dietBut the standard protocol looks like the image above.

5% of carbs = 15-20g of carbohydrates a day!

1 small banana = 23g of carbs

Carbs are found in foods such as cereal, bread, pasta, rice, noodles, legumes, fruits and some starchy vegetables (beetroot, parsnips, potatoes etc).
