Humans are evolutionary adapted to use any of the macro nutrients (fats, proteins, carbohydrates) for energy.
Ketosis is a metabolic state
in which your body uses stored fat rather than carbohydrates as your main energy source.
diets are being used not only for weight loss but also as a tool for metabolic
healing. This is because ketosis
· Takes the reliance off the adrenals for blood sugar regulation ( therefore benefits those with blood sugar/ insulin resistance problems) 1
· Resets leptin, the hormone that controls appetite and also energy expenditure, so helps to regulate energy balance, which is important to support healing
· Aids weight loss. Ketogenic diets can yield greater weight loss over medium carbohydrate diets 2, 3 and low fat, medium carb diets 4,5. This is because eating excess refined carbohydrates leads to fat storage. High natural healthy fat intake leads to fat loss
· Promotes fat cycling, rather than storage, can also encourage elimination of any fat soluble toxins stored in your fat cells6
· Originally designed to offset excitatory brain agitation in epilepsy, ketosis calms the neural activity and is also being used for Alzheimers, Parkinson, migraines and other neural degenerative diseases 7
· Ketones are anti inflammatory so drive down any other inflammation to allow healing and this is being investigated for reducing cancer tumours7,8,9
However! , there
are however pitfalls and this needs to be entered with caution and guidelines so
you don’t do yourself more harm than good. This includes
- Getting the right balance of nutrients with a high fat, moderate protein and low carbohydrates
- Guidance for transition into ketosis as unguided this can be stressful on the body
- Making sure you are not in ketosis long term as this can downregulate your metabolism
- Consideration of adaptations of the ketogenic diet for those undertaking cardio/ aerobic/ athletic training
I had a
step change in my own health when following a guided ketogenic diet. If you are
