A keto or ketogenic diet is a very low-carb diet, which can help you burn fat more effectively. Many people have already experienced its many proven benefits for weight loss, health and performance. It’s also used and recommended by many doctors.
With this website you’ll learn how to eat a keto diet based on real foods and all the information you will need to succeed on keto.
The “keto” in a ketogenic diet comes from the fact that it allows the body to produce small fuel molecules called “ketones”. This is an alternative fuel source for the body, used when blood sugar (glucose) is in short supply.
Ketones are produced if you eat very few carbs and only moderate amounts of protein. The liver produces ketones from fat. These ketones then serve as a fuel source throughout the body, especially for the brain.
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.4
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off.6 This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.7
When the body produces ketones, it enters a metabolic state called ketosis. The fastest way to get there is by fasting – not eating anything – but nobody can fast forever. I will be doing posts about intermittent fasting in due course.
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.9
Who should NOT do a ketogenic diet?
There are controversies and myths about a keto diet, but for most people it appears to be very safe. There are, however, three groups that often require special consideration:
- Do you take medication for diabetes, e.g. insulin?
- Do you take medication for high blood pressure?
- Do you breastfeed?
As with all diets please consult your doctor if you are unsure if this diet is suitable for yourself.
