Ketogenic Diet

NaturMents / Ketogenic Diet

Health supplements are all the fad now. You are probably bombarded with crowds of different types of supplements from all sides every day in the market. But often, it takes some effort and research to find out what your body needs and more than that, what each abbreviated ingredient expands to. Just the information is not enough either. You certainly need to educate yourself on what they do and how they benefit your health.

But just suppose that you do have an idea of what your body needs. And if it is something that sounds like ‘ketogenic diet’, there are a few things you have heard about. However, if you are still new to the term ‘Ketogenic Diet’, let’s ease into it.

 

What is the Ketogenic Diet?

Ketogenic diet is basically a low carb diet and it is increasingly being adopted by thousands of people owing to its health benefits including fitness. Under the ketogenic diet, one consumes a high amount of fat, medium quantities of proteins and a low amount of carbohydrates. The goal of this diet is to induce the burning of fat for energy instead of carbohydrates. The outcome is quite great when you stick to it. But how? You need to get the basics right about how energy is used by the body to fully understand how a keto diet works.

 

The Basics of Energy Consumption

A normal daily diet has a higher portion of carbohydrates. The body is used to taking the easy way out to produce energy in a normal high-carb diet. Carbohydrate is broken down to glucose quite easily and the glucose is taken to the bloodstream by insulin. As easy as it is, Glucose is the favourite energy source of your body and in the presence of glucose, the body uses it first for energy. Now, you have a small picture of why fat remains untouched in your body.

 

When Carbs are Replaced by Fats

When your intake of carbohydrates is cut down and more fat is introduced to your diet, the metabolism takes a turn. The normal amount of carbohydrates for immediate breakdown and energy release is unavailable. If it seems baffling, let us assure you – it is a turn for the better. Your body is thrown into a metabolic state called ketosis. There, and that’s where the ketogenic diet comes from!

 

Ketosis?

Yes, Ketosis.

Ketosis is the process by which the body survives starvation. When there’s no food, that is the process your body undergoes – turning to stored fats for energy. When the process is induced, i.e. with a ketogenic diet, you are not actually starving your body. You are just starving your body of carbohydrates

Ketosis takes place when your body starts using fat for energy in the absence of its normal amounts of carbohydrate. The liver gets busy forming ketone bodies from fatty acids for the body to burn. The body under the ketogenic diet is overloaded with fats instead of carbohydrates as the primary fuel. The body adapts to the state of ketosis or gets ‘keto-adaptive’ quite dramatically. This renders it highly efficient in burning fat. (Do you hear echoes of ‘fitness goals’?)

 

Ketogenic Diet – Classification

When the changes a ketogenic diet can bring to your body sounds awesome and just the right thing you have been waiting to start, don’t jump into it yet and haul keto diet products. It would be unwise if you are not well versed with what your body truly needs and which type of Keto Diet is appropriate for you. Because, there are three types of ketogenic diets, appropriate as per the intake of carbohydrates.

We’ll break it down for you.

  • The Standard Ketogenic Diet (SKD):

This is the most recommended type of ketogenic diet as well most commonly used. The total carb intake per day is kept within 20-50 grams with a dash of moderate amounts of protein and topped with a high fat consumption.

  • Targeted Ketogenic Diet (TKD):

This type of ketogenic diet allows within 25-50 grams of total carbs. Alternately, lesser than that amount can be consumed about 30 to 60 minutes before exercise.

  • Cyclical Ketogenic Diet (CKD):

This involves a break in the regular ketogenic diets where you are on a low-carb, ketogenic diet for many days interrupted by a few days of high-carb intake.

An additional type of keto diet is the High-Protein Ketogenic Diet, which is very much like SKD, with extra amounts of protein.

 

Is Ketogenic Diet Merely Any Low-Carb Diet?

To think that would endanger your keto-diet goals. Not all low-carb diets are ketogenic. Ketogenic diet has set levels of carbohydrate intake and variations in this is highly prone in just any low-carb diet. A low-carb diet is often not enough to induce ketosis. Plus, there is more chance for followers of an unsystematic low carb diet to go on a detour eventually and end up having more carbohydrates than allowed for ketosis to occur.

 

The Right Way to Keto

A common error that happens in those who mix up some low-carb diets with keto diets is loading up on protein. Other low carb diets recommend high protein whereas standard ketogenic diet recommends a moderate intake of protein. Protein intake should be limited just enough amount to maintain the muscle mass. Not more.

The body can break down protein to produce glucose through the process of gluconeogenesis. So, high protein amounts can also raise your blood sugar levels and consequently, the insulin levels. High insulin levels hinder the ketone production.

Meanwhile, fats are saviors, contrary to common belief. Fats have almost no effect on your blood sugar levels and insulin levels. The availability of fats for fuel also protects the muscle mass by not pushing the body to leach out proteins for fuel. This is important to maintain a lean and healthy body.

The general ranges for each macronutrient, i.e. fats, proteins and carbohydrates in a ketogenic diet can be broken down as follows:

  • Calories from fat: 70-80%
  • Calories from protein: 20-25%
  • Calories from carbs: 5-10%

The ranges can slightly vary as per the requirements of each person.

 

  • Carbohydrate Consumption:

 

In most cases, the amount of carbs taken is limited to 20 to 50 grams. The number can go higher in some persons as each one’s body is different and goes into ketosis at different rates.

 

  • Protein Consumption:

 

The protein requirement of your body while in keto diet has to be determined by some factors. The factors to consider are:

  1. Gender
  2. Height
  3. Ideal body weight
  4. Lean body mass
  5. Activity (sedentary, moderate or high)

The ideal amount of protein that can be consumed in order to maintain ketosis is not more than 1.5 to 2 grams per kilogram of lean body mass. This will prevent the breakdown of protein for glucose and facilitate ketosis.

 

  • Fat Consumption:

 

Finally, after determining your carb and protein requirements, the remaining calories have to be filled in by fats. The type of fat eaten is crucial in a ketogenic diet. Consuming a lot of oils which are rich in Omega-6 fatty acids will be inflammatory in large amounts. The ideal fat sources are those rich in monounsaturated and saturated fats whereas polyunsaturated fats are not preferred. The following is a list of commonly preferred fat sources:

  1. Medium Chain Triglycerides (MCT Oils) / Coconut Oil
  2. Olive Oils
  3. Butter (preferably from grass-fed cows)
  4. High Oleic Sunflower Oil or Safflower Oil
  5. Dairy Products including Full-Fat Cheese
  6. Vegan fats like Avocado
