Has your weight given you more issues than your favorite magazine subscription? Well it’s time to “keto” your diet!

But first, let's get straight into the ketogenic diet for definition.

What Is the Keto Diet?


The ketogenic (keto) diet is nutritional plan that gets an individual eating a combination of low carbs and high fat.

The goal of the keto diet is to replace high carb intake with dietary fat to achieve an optimal wellbeing.

Some nutritionists/dieticians scoff at this diet because they feel it’s unhealthy to lower your carb intake while consuming a high amount of fat.

Yet, versions of the ketogenic diet have been used to successfully treat drug-resistant epilepsy in children since the 1920s. (1)

Last time I checked, a thing being used to treat an illness is called…medicine. Moving along...

In this article, you will learn about what makes the keto diet not only an effective method to lose weight, but also a method to become healthier as well.

What Does “Keto” Mean?

Keto (ketogenic) refers to or the metabolic process of ketosis where your body uses fat to produce ketones for energy instead of carbs or blood sugar.

Ketosis is a natural process the body initiates to help us survive when food intake is low, particularly of carbohydrates. During this process, we produce ketones, which are produced from the breakdown of fats in the liver.

Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose.

How Do Carbs Affect Your Weight?

The answer to that is…. Water weight. You can thank glycogen for this.

Glycogen is a form of glucose stored in the liver & muscle tissues and the primary dietary source of glucose is carbohydrate. Medical science shows that every 1 gram of glycogen carries 3 to 4 grams of water. Research has proven that a high carb intake increases glycogen levels while low-carb intake reduces it. (2)

So If you take into account that the average man can store up to 15 grams of glycogen per kg of bodyweight, that’s enough to make a huge impact on the weight scale, particularly if he consumes a copious amount of carbs. (3)

Wait, So Body Fat Is Not A Factor???

Yes, body fat is definitely a factor. In fact, ever since people started consuming more carbs (sugar), the U.S. obesity rates has risenThe number of U.S. citizens who are categorized as obese has nearly doubled over the past 30 years.

In addition to being stored in the liver and muscle tissues, glycogen is stored in fat cells. This is the same glycogen that holds 3 to 4 grams of water. By lowering carb intake, you deplete your regular stores of glycogen which shows as weight loss on a scale.

This is the reason an obese person who follows a low-carb diet will always lose more weight versus a slimmer person; they carry more fat cells (each containing water-holding glycogen).

Types of Ketogenic Diets

  • Targeted Ketogenic Diet (TKD) - This version is where you can consume carbs around a workout.
  • Standard Ketogenic Diet (SKD) - This version focuses on high-fat, moderate-protein, low-carb diet. It typically contains 75% fat, 20% protein and only 5% carbs.
  • Cyclical Ketogenic Diet (CKD) - This version involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
  • High-protein Ketogenic Diet - This version is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein and 5% carbs.

What Are The Foods to Avoid?

  • Tubers - White potatoes, tams
  • Alcohol - Wine, beer, and cocktails all have carbohydrates in them.
  • Gluten - Bread, pasta, tortillas, etc
  • Condiments and sauces - ketchup, soy sauce, and barbecue sauce that contain high sugar
  • Salty processed snacks - potato chips, popcorn, pretzels, nacho chips,crackers, popcorn
  • Grain-based foods - wheat, barley, rye, cereal, oatmeal, corn, popcorn
  • Sugary foods - Fruit juice (even 100% fresh!), ice cream, cakes, cookies, cupcakes, candy

What Are The Keto Approved Foods?

  • Meat - Poultry, Fish, beef, lamb, chicken, eggs, etc
  • Vegetables - Asparagus, Kale, spinach, etc
  • Avocados
  • Berries - trawberries, blueberries, raspberries, blackberries, etc
  • Healthy oils - olive oil, coconut oil, etc.
  • Condiments for dipping (hummus, guacamole, salsa)
  • Nuts and seeds - macadamias, walnuts, chia, flax, hemp)
  • Sweeteners - stevia extract and erythritol
  • Milk Alternatives - almond, coconut, hemp, rice

How Many Carbs Are There on Keto?


The ideal carbohydrate load for someone on the keto diet is a maximum of 20 grams per day.

You’ll find some sites lately that have been tossing around the 50 gram number, but in truth it will be much harder to achieve and maintain ketosis at that level of consumption.

The fact is, the fewer carbs you eat the easier it will be for your body to transition to burning fat for energy.

And once it does that you are officially in ketosis because your liver begins producing ketone bodies to metabolize the fat.

Staying in ketosis and adhering to the 20 grams of carbs per day limit will require you to get used to reading labels and being aware of hidden carbs in things like condiments, low-fat yogurt and salad dressing.

Benefits of the Keto Diet

1. Increased Weight Loss

Numerous studies have touted the weight loss benefits of a low-carb diet. The low carb intake makes your body produce ketones in the liver to be used as energy (called ketosis), a byproduct of burning body fat - essentially utilizing fat for fuel.

Reducing carbs allows the body to use glycogen buildup within your fat stores as fuel, resulting in weight loss.

This effect is doubled when you burn glycogen by exercise.

In addition, the moderate protein intake protects your muscle tissue from being used as fuel (a process called Gluconeogenesis).

2. Lower Risk Of Developing Chronic Diseases

Type-2 diabetes, stroke, and heart disease are three of the leading causes of death in the world, however, it's shown that all these chronic diseases can be prevented from the keto diet.

One study conducted on an obese individual who followed the ketogenic diet for 24 weeks and the results are as follows:

Significant risk reduction in chronic diseases by weight loss, decreased levels of triglycerides, LDL cholesterol (the bad cholesterol) and blood glucose, and increased levels of HDL cholesterol (the good cholesterol). (4)

3. Lowers Blood Pressure


If you or your family have a history of high blood pressure, following a low-carb diet may be a godsend.

Medical researchers tout low-carb diets like keto as an effective method to reduce blood pressure.

One way that people develop high blood pressure is eating too many refined carbs over a lengthy period of time.


The reason most people consume so many refined carbs is due to how poorly it satisfies their appetite.

4. Prevents Binge Eating


The number one reason most diets fail long-term is because they leave people hungry as heck and causes them to binge eat which causes a yo yo dieting effect.

That’s not the case with the ketogenic diet. Research illustrates that a high protein, low-carb diet reduces hunger and lowers food intake. In addition, the amount of dietary fat you’ll consume will leave you very satiated. See this list of high protein foods for muscle building.

Another problem about most other diets is that they’re energy zappers. That’s not the case when you go “keto.”

5. Increased Energy Levels By Boosting Brain Power


The main reason for this is; ketones replaces glucose as the brain’s fueling source. When carbs are eliminated or minimized, ketones provide up to 70% of the brain’s energy needs; this boosts mental focus and alertness throughout the day.

Another interesting fact is that ketones keep people who go through prolonged periods of starvation (e.g., coma patients) alive.

Then again, it makes sense considering that intermittent fasting works well in conjunction with the keto diet.

Are There Any Side Effects?

When your body is suddenly exposed to a new way of eating, side effects are a likely occurrence.

With that said, the keto diet does have its side effects but they’re curable.

  • Headaches - Drink water with salt sprinkled in it
  • Feeling tired and cranky - Eat more fat
  • Leg cramps - Drink water with salt & supplement with magnesium
  • Constipation - Drink more water, add extra salt to foods & eat more high fiber, non-starchy vegetables
  • Bad breath - Brush your teeth and tongue more often. Eat a few more carbs if the smell becomes a long-term issue.
  • Reduced exercise performance - Drink plenty of water with salt prior to exercising. Be patient because it will take time for your body to adjust from being a sugar-burner to burning primarily fat for energy, even in the muscles.

How To Get Into Ketosis?


In theory transitioning to ketosis isn’t all that difficult. That’s because ketosis is the body’s natural backup state in case carbs aren’t available.

Anyone who has ever engaged in prolonged fasting has undoubtedly achieved ketosis.

And any time the body enters survival mode because food is unavailable it again transitions to ketosis so that it can use fat stores for energy.

But even though ketosis is a natural state for the body it is still a backup position. Therefore, it doesn’t take much to bounce you out of ketosis and back to your natural state of burning carbs. So achieving and maintain ketosis takes some determination and perseverance. So…

  • Limit your carb intake to 20 grams per day.
  • Eat plenty of healthy fat so your body has the fuel it needs.
  • Don’t go overboard on the protein. A couple of grams per day is usually enough. See post on Low carb protein powder and keto friendly at the same time.
  • Avoid snacking. This is one of the quickest ways to bounce yourself out of ketosis.
  • Don’t eat anything for 16 hours of each day. This intermittent fasting will instill discipline in your process and boost ketone production.
  • Make sure to pair your keto diet with exercise.
  • Take exogenous ketone supplements to reach ketosis faster.

How Do You Know If You’re in Ketosis?

If you are diligent in sticking to the 20 grams of carbs per day limit you should enter ketosis within just a few days. If you are not watching out for hidden carbs or eating “cheat meals” achieving ketosis will be more difficult.

Once your body successfully transitions to ketosis you’ll feel the difference. Most people experience an increase in energy, the beginnings of weight loss and a heightened sense of alertness.

In addition, there are several different testing kits on the market you can use to affirm that you are in ketosis. Some test urine while others analyze your breath.

There are also a few less pleasant things to look for. Taken together they add up to what is commonly referred to as the “keto flu”. But don’t worry, you don’t actually have the flu. It’s just your body adjusting to the switch from carbs to fat.

Keto flu symptoms can take the form of headaches, cramps, bad breath, a sense of fatigue and perhaps a bit of difficulty getting to sleep. Or all of the above. In the vast majority of people these symptoms pass with just a few days. And as long as you stay in ketosis they shouldn’t return.

Combining Intermittent Fasting & the Keto Diet


The main reason you are reading this article is because you’re interested in losing weight, that’s understandable.

With that said, using intermittent fasting (IF) along with the keto diet maximizes weight loss. Intermittent Fasting is a term for an eating pattern that cycles between periods of fasting and eating.

Like the keto diet, several studies have shown IF to be effective weight loss method as well as reducing the onset of chronic diseases such as type-II diabetes. That’s why it makes sense to use IF in conjunction with the ketogenic diet. (5)

The easiest method to start is the 16/8 method. This method involves skipping breakfast and restricting your daily eating period to 8 hours.

For example from 12pm to 8pm, afterwards, you “fast” for 16 hours in-between. Utilizing IF and keto together will give the following benefits:

  • Burn more body fat
  • Have more energy as you start your day
  • Reduce chronic inflammation
  • Improve brain function
  • Thoroughly cleanse toxins from body cells


How Long Does It Take To Reach Optimal Ketosis?

Warning: The keto diet takes time for your body to get adjusted to it.

With that said, reaching optimal ketosis could about 3-7 days, depending on your body type, activity levels, and what you’re eating. However, how strict you’re with your carb intake leads your body to reaching ketosis faster.

How Can I Track My Carb Intake?

Following the keto diet will naturally have your carb intake low. However, there are smartphone health apps such as MyFitnessPal that makes it easy to track your carb intake.

What Are The Common Mistakes People Make?

The three most common mistakes people make are:

  • Consuming too much protein
  • Mistaking any low-carb diet for very low-ketogenic dieting
  • Not allowing for a long enough adaptation period

Success Stories

These two ladies were having a difficult time keeping weight off until they discovered the keto diet.

1. Misty

Misty never had to deal with weight issues until she reached adulthood. Like a lot of women she put on weight during pregnancy. That wasn't a problem at first. But after several children the weight she put on while pregnant began to stay on after she gave birth.

After some friends at work proposed a "keto challenge" where they would all try the keto diet and compare weight loss results, Misty did her research and decided to take friends up on it.

After months of fits and starts she finally got serious and within 12 weeks she had shed and incredible 40 pounds. In this video she tells her inspirational story of keto success.


2. Suzanne

On the day she decided to go keto Suzanne weighed 289 pounds. By sticking to a formula of 70% fat, 25% protein and 5% carbs she began to lose weight. Eight months in Suzanne finally dropped from being officially "obese" to being officially "overweight".

By the end of her first year on the ketogenic diet she had lost an astonishing 100 pounds.

  • Almost everyone takes supplements nowadays. They have become part of our daily diet, and the industry is huge to say the least. Yes, these companies earn billions of dollars. I personally think that everyone needs them especially with all the unnatural foods we have now! Fast food here, fast food there, fast food everywhere. As much as we want to eat healthy, it can be difficult to do that when everything is already processed. The only way to go about it is to supplement so we get all the things we need in our bodies and make sure that we’re all healthy and safe all the time!

  • how i wish we can still be at a time where every thing we need is right in the backyard. I remember living at my grand mother’s home and she had chilis, tomatoes, onions, garlics and some leaves in her garden –we can just pick something if we need it! for free! good times. anyway, I live in a condo now and I don’t have a garden so the farmer’s market is my friend when it comes to condiments and cooking stuff.

  • “Over thousands of years, one generation has passed its “survival genes” on to the next. So thanks to our ancestors, we are equipped to subsist on minuscule amounts of the essential nutrients, just in case a famine comes along. But as I said before, this insurance policy remains effective only into our twenties — just long enough for us to reproduce. It includes no provision for aging.”

    this one is from chiro dot org, do you agree? I do! We are able to survive with the least amount of nutrients for as long our bodies can handle! But this doesn’t mean you have to starve, just eat healthy, make sure you get enough sleep, and you’ll be fine
