ketogenic diet

In short it’s a diet that is a lot closer to what your human physiology has evolved to eat, and many experts think this is a far healthier way to eat compared with modern carb-laden diets.

Ketosis, in a nutshell, is the state in which your body is burning fat for energy instead of glucose (carbohydrates).

But What About My Blood Sugar?

Most people think that their main fuel source is glucose or ‘sugar’. For most people it is, although they may not realise that it doesn’t have to be. There is another option.

Lots of my patients complain of having bouts of low blood sugar and feeling tired, shaky, no energy. These feelings generally drive them to eat carbohydrate based food to boost their blood sugar and get their fuel levels up.

But, diets with significant amounts of carbohydrates are a modern phenomenon, one that our physiology hasn’t really evolved to cope with.

High carb diets (at the expense of good quality fats) have a strong link to obesity and loads of illness like heart disease, arthritis and cancer.

In truth we don’t ever have to eat sugar or starch of any kind to be healthy.

Glucose is only actually needed in an ongoing every day way to fuel your red blood cells. These are the cells that make your blood look red, they carry oxygen around your body. This glucose can be made from protein.

Everything else in our body can run really well on ketones.

What is Ketosis?

Ketosis is when your body is using ketones to make energy. Ketones are by-products of fat breakdown. They can be used by all parts of your body (except your red blood cells).

Humans, and what we evolved from, ate a ketogenic diet for millions of years. So it must be a pretty safe diet to get us this far! This means that pre-agriculture all humans were in a state of ketosis and did not rely on their blood sugar level and carby snacks to get them through the day.

Here’s an interesting fact. A ketogenic diet was the number treatment for people with epilepsy until the first epilepsy drug was developed in 1938. This says that a high fat diet is good for your brain (and high carb isn’t).

A ketogenic diet is very low carb (usually just green leafy veg and fruit, no grains), high fat with enough protein.
