Ever since the Atkins Diet shot to fame in the early 2000’s, low carb diets have entered the public nutrition thinking, just like the ketogenic diet. They have been credited with dramatic weight loss, clearing up ailments, allowing some astonishing dietary choices and changing the public nutritional thinking forever.
The latest low-carb diet gaining popularity is the ketogenic diet. What is the ketogenic diet and how do you follow it? Read on to find out…
Essentially the low-carb theory (the one that binds a lot of these low carb diets together) goes that if you reduce your carbohydrate intake you force your body to using fat as a main fuel source. The longer this process occurs, the more fat you lose.
It also claims that it’s an easy way to lose weight because as long as you keep your carbohydrate intake low enough, you can eat a whole load of fantastic foods such as bacon and sausages, burgers and cheese, steak, eggs etc.
Lose huge amounts of weight eating amazing food and feeling great! Sounds fantastic doesn’t it?
That’s the marketing claim anyway. The reality is slightly different.
What is the Ketogenic Diet?
The Ketogenic (keto) diet is an extreme version of low-carbohydrate diet. It actually has its origins in the medical world, where it has been used to effectively treat conditions such as epilepsy, diabetes, PCOS, cardiovascular diseases etc. It has also been experimented with as a possible diet that could have beneficial effects when it comes to cancer.
The research on a lot of this is showing potentially ground-breaking effects from this form of extreme low carbohydrate eating.
What sets the keto diet apart from other low carb diets is the fact that the keto diet allows for almost zero carbohydrate intake, instead forcing the body to enter a state of ‘ketosis’. This state is defined as…
How Do You Reach Ketosis?
There are a number of ways you can enter ketosis, but the most important are nutritional – you absolutely have to cut your carbohydrates right down to almost zero. You can then take exogenous ketones to help speed the process, alongside using MCT (medium chain triglyceride) oil and exercising daily to burn off additional carbs.
Getting into a state of ketosis takes a little time – anywhere between 24 hours and a week, depending on a number of factors such as your diet, body type, age, activity levels, previous health history etc. It’s not the same for everyone, but typically speaking the more used to ketosis you are, the quicker you’ll enter a ketogenic state.
You will also need to assess where you are by testing your urine with ketone strips that will help you determine whether or not you are in ketosis. Once there, it’s a question of regularly testing to ensure you remain in ketosis and make nutritional/activity adjustments accordingly.
There are other, more observational signs but they are anecdotal and not especially accurate.
If Carbohydrates are Removed, What Do You Eat?
On a keto diet, there is essentially no room for carbohydrates – even the vegetable choices are vastly reduced because they contain sugars. Instead, the diet is based around high protein and fat food sources such as meat, fish, eggs, dairy and very high fibre, low sugar vegetables. Here is a general list of the kinds of foods you can eat on a keto diet…
- Fibrous vegetables (broccoli, cauliflower, savoy cabbage, spinach)
- Diary (butter, cottage cheese, natural greek yogurt)
- Nuts and seeds
Your diet will be mostly (around 70-80%) fat, which is a huge change for most people. Protein will make up most of the rest, with around 5% coming from carbs (usually naturally-occurring sugars in the meat and limited vegetable elements of your diet). If you can get over the psychological hurdle of eating so much fat, you’ll probably be OK! And we highly recommend the same diet for hair transplant Turkey patients, too!
Obviously care has to be taken on the keto diet to ensure you stay in ketosis – if you consume too much carbohydrate you’ll slip out of ketosis and start using those carbs for fuel.
Regular testing is imperative if you are to stay in ketosis. For beginners to ketosis, it’s worth investing in a few ketosis cook books to give you plenty of recipe and meal ideas that will keep you on track.
How Do You Feel in Ketosis?
Once you have become fully fat-adapted, people report feeling amazing – full of energy, they lose weight and many ailments typically clear up. However, in the process of reaching ketosis and fat adaption (when your body is used to using fats for fuel), most people report suffering from ‘carb flu’, where they feel terrible – headachy and tired as their body undergoes an almost ‘cleaning out’ process.
There are a lot of people who also report they struggle to manage more intense types of exercise whilst in ketosis, but there are ways in which it can be achieved. It’s a case of testing how you feel and adjusting your exercise accordingly. Some athletes maintain a ketogenic diet, so it’s worth doing some research and experimentation.
