Clearing up KETO myths

Clearing up KETO myths

The Ketogenic diet refers to a low carb/high fat diet (<10%CHO,>70%FAT)
Where your body switches to ketones over glucose as a fuel source.

Ketosis refers to your body breaking down fats into ketones.

Ketogenisis is when your liver produces ketones via fasting or lack of carbs.

Ketoacidosis is when blood ketone levels exceed 7Mmol and is only of real concern for insulin dependant diabetics and severe alcoholics.

Protein is gluconeogenic meaning your body can turn excess protein into glucose, hence any diet over 20% protein is not considered to be ketogenic.

Your body requires approx 120gm glucose per day for obligatory glucose users (red blood cells, central nervous system, anabolic metabolism).

Your body produces roughly 120gm glucose per day through gluconeogenesis of amino acids and glycerol.

Ketogenic diet does not mean you will lose more fat, simply implies your body burns fat as a fuel source, calorie deficit still matters.
In fact, it has been shown weight loss remains the same when protein intake is matched to a similar calorie diet.

Health Benefits to Ketosis;
*Lowering insulin sensitivity and hunger has shown great promise, yet again has shown no extra advantage to a calorie deficit diet.
*Recent studies show Alzheimer's patients have had success via offering the brain a secondary fuel source in ketones.
*Some studies show Epilepsy patients have a reduced number of seizures while in ketosis.
*Cancer cells (in some cases) have shown a reduced/slower rate of growth, since glucose is the main energy supply to cancer metabolism (1931 Nobel prize in medicine Otto Warburg).


Summarising:
A lot of studies around the ketogenic diet have been taken out of context.
Keto can be extremely difficult to stick too and for weight loss, most people tend to bounce back in the long run.
It has shown success in some health applications. However remain cautious of exogenous ketones and if trialling a true ketogenic diet I recommend to supplement with electrolytes.
Without a doubt I would present evidence of the keto diet to my oncologist if I was diagnosed with cancer.
(Always consult your health care professionals before starting any new treatments).
