A Ketogenic Diet for Beginners

A ketogenic diet (keto) is a very low-carb diet, that turns the body into a fat-burning machine. It has many potential benefits for weight loss, health and performance. But there are also potential drawbacks and side effects.

A ketogenic diet is similar to other strict low-carb diets, like the Atkins diet or LCHF (low carb, high fat). These diets often end up being ketogenic more or less by accident. The main difference between strict LCHF and keto is that protein is restricted in the latter.

A keto diet is designed specifically to result in ketosis. It’s possible to measure and adapt to reach optimal ketone levels for health, weight loss, or for physical and mental performance.

 

The “keto” in a ketogenic diet comes from the fact that it makes the body produce small fuel molecules called “ketones”

This is an alternative fuel for the body, used when blood sugar (glucose) is in short supply.

Ketones are produced if you eat very few carbs (that are broken down into blood sugar) and only moderate amounts of protein (excess protein can be converted to blood sugar).

Ketones are produced in the liver, from fat. They are then consumed as fuel in the body, including by the brain. This is important as the brain is a hungry organ that consumes lots of energy every day and it can’t run on fat directly. It can only run on glucose… or ketones.

On a ketogenic diet your entire body switches its fuel supply to run almost entirely on fat. Insulin levels become very low and fat burning increases dramatically. It becomes easy to access your fat stores to burn them off. This is obviously great if you’re trying to lose weight, but there are also other less obvious benefits.

When the body produces ketones it’s said to be in ketosis. The fastest way to get there is by fasting – not eating anything – but obviously it’s not possible to fast forever.

A keto diet, on the other hand, can be eaten indefinitely and also results in ketosis. It has many of the benefits of fasting – including weight loss – without having to fast.
