What is Keto Diet: A Comprehensive Beginner's Guide

What is Keto exactly?

The Keto diet is a specific nutritional plan that forces the body to burn fat instead of sugar.

By reducing your carbohydrate intake to near-zero levels, glucose - the energy your body produces from sugars - can no longer support your body’s activity.

The main idea is to eliminate high-carb items from the diet and replace that energy with high-quality fats and proteins. You could describe it as a low-carb, high-fat diet.

We usually get most of our sugars from carbohydrates. You may not know that carbs become simple sugars in the gut, providing little more nutritional value than a sweet treat.

Without all of that glucose, the body must utilize another fuel source.

Using fat as energy

At this point, your body begins to use stored fat as energy.

The liver converts this stored fat into molecules called Ketones, which then supply energy to your brain and muscles. Hence the name: Ketogenic diet, or “Keto” for short.

This state is specifically called nutritional ketosis.

Ketosis is a natural metabolic state, found commonly in pregnant women, infants, or those fasting or experiencing starvation.

You might be asking: is the keto diet safe?  Intentionally activating this state is safe for most people, but may not be the right choice for every individual.

Why would I want a ketogenic diet?

A ketogenic diet may provide an individual with a slew of health benefits.

If you are seeking long-term weight loss, or if you are interested in the reported cognitive benefits of ketosis, it may be right for you.

Because this diet induces your body to burn fat, it’s become a preferred method of weight loss; but its origins are medical.

Russel Wilder first coined the term and established the ketogenic diet in 1921 as a means of treating epilepsy.

For thousands of years, fasting has been believed to remedy epilepsy, and more recently it's been explored as a treatment for type 2 diabetes. 

Doctors have recently discovered that epileptic conditions can often be improved by ketosis, decreasing the frequency and severity of seizures.

And by removing all unnecessary sugar from the diet, blood sugar levels are lowered substantially.

Is it for me? Can it help with weight loss?

But even those without a medical condition can find benefits of a keto diet. Those seeking to lose weight have found ketogenic diets are much more effective than other plans and allow them to eat a satisfying amount while still succeeding in weight loss.

Modern medical advice now tells us that fat loss doesn't require starving oneself.

It is indeed a fantastic way to see long-term weight loss if you stay on track.

While the positive effects are desirable, and nutritional ketosis is considered quite safe, launching into a different eating plan without contextual knowledge could lead to malnutrition.

The good news is starving yourself isn’t necessary to achieve ketosis and become a fat-burning machine; just a dedicated regimen.

So let’s dive into the specifics with this guide to Keto.

What are the rules for a Ketogenic Diet?

The basic idea of Keto diets is very simple: fewer carbs. Hence, the rule for ketonic diet is:

70% fat, 25% protein, 5% carbs
(you read that right)

We eat more carbs a day than we typically think.
The idea is to get your net carbs as low as possible.

That means you’re looking at 20-30g of carbohydrates per day. 

For perspective, the average banana contains some 25g of carbohydrates.


Keto diet basics

You’re replacing all of this energy, which we habitually get from bread, pasta, rice, and other sugars, with good fats: oils (coconut, olive), butter, cheeses, avocados, etc. - and also a moderate amount of protein intake.

The desired macronutrient breakdown for a Keto diet is (approximately) as follows: 70% fats, 25% protein, 5% carbs. 

Because its based on a percentage, how many carbs on keto can change daily and for each person.  Variants of Keto have different keto diet rules owing to the contexts they’re used in.

Different Kinds of Keto

Standard Ketogenic Diet (SKD): This is what most think of as the classic variation. The breakdown is as above, 70-25(20)-5(10)

    Cyclical Ketogenic Diet (CKD) 

    Cycling through two days of higher carb intake and five days of strict Keto, this weekly method has been used by athletes to refuel the body before intense periods of exertion. It’s been studied less than the SKD.

    Targeted Ketogenic Diet (TKD)

    Evoking the same principle as the CKD, this method allows for (intentional) injections of high-carbohydrate foods into the routine for athletic or otherwise high-intensity purposes. Again, this has not been studied as extensively, and the expertise of a registered dietician is wanted to make this setup work.

    High Protein Ketogenic Diet

    Almost identical to the SKD, this variant shifts the macros slightly: 60% fat, 35% protein, 5% carbs. Suited perhaps to bodybuilders or those who otherwise require higher volumes of protein, one should be cautious that an excess of protein can jolt your body out of the ketotic state.


    For this article, we’ll be referring to the SKD, the most widely studied and practiced form of Keto eating.

    Keto vs Paleo

    A choice for some is between keto and paleo lifestyles.  The two diets both have positives and negatives but they work very differently in the body.

    But what is the paleo lifestyle? With its focus on whole foods and fresh vegetables, it's certain is a paleo lifestyle healthy but it may not be the best for weight loss for everyone.  It can be overwhelming at times with its specific restrictions and you may find yourself frantically researching “what is gluten-free flour?” in a grocery store aisle.

    If you've previously gain weight on paleo lifestyle, the keto diet may be a better fit.  By entering a state of ketosis for a short time, you can quickly burn fat and some can even combat more serious health conditions like high blood pressure or cholesterol.  

    On the flip side of the coin, if you find yourself having some negative side effects from the keto diet, you might consider reading about how to start paleo lifestyle plan.

    How do I start Keto, for beginners?

    Maybe you’re not looking for a complicated, acronymized eating plan. We get it. One of the greatest benefits of keto is its simplicity.  A good comparison is keto vs paleo

    Keto works with your current diet and lifestyle while still helping you lose weight.  The paleo lifestyle rules are great for people looking to completely reboot their eating habits.  While many lose weight on paleo, it can take a lot more research and keto's simplicity makes it great for busy dieters who want their new diet to look a lot like their old one.

    Prioritize healthy fats and good proteins, and you’re most of the way there in creating your own custom keto diet.

    What can I not eat?

    Avoid anything high in carbs.

    This includes:
    • Bread
    • Pasta 
    • Rice 
    • Cereals
    • Baked goods (exceptions for Keto-specific recipes)
    • Chips and crackers
    • Most fruits
    • Including juices!
    • All added sugars
    • Sweetened yogurt
    • Honey, syrup, etc.
    • Potatoes (and other starchy tubers)
    • Beer

    Replacing these carbs with fats for energy requires a good meal plan, so let’s specify the foods to buy and the foods to steer clear of.

    The good news is more and more food companies (like Kevin’s) are devising delicious Keto alternatives to high-carb favorites!

    Rather you're already a customer of a meal kit company or you're wondering, "What are meal kits?"  You might be surprised at the amount of keto options many companies have.

    Keto Diet Foods: What You Can Eat and What to Avoid

    The cornerstone of the Ketogenic diet is the fats your body burns for energy in the ketogenic state.  When learning how to start a keto diet, its all about finding low-carb ingredients and sources of good fat. These ingredients can be incorporated in many ways, and the list of options is long!

    Be sure to try many different good fats to find the ones you prefer (it’ll make Keto a lot more enjoyable).

    • Butter
    • Ghee
    • Coconut oil
    • Avocado oil
    • Olive oil
    • Lard
    • MCT oil

    These and other saturated fats are central to the Keto diet. Use them in cooking and to finish dishes.

    Kevin's Natural

    Fry up some eggs in butter. Toss a salad with a hearty glug of olive oil. Coconut oil seems to be good with everything, and it contains MCT (medium-chain triglycerides), which have been shown to contribute to the production of ketones.

    Natural polyunsaturated fats like those in fish and other animal proteins are also good resources.

    Because this is a low-carb diet and we typically receive most of our daily energy from carbs, it's crucial you eat good fat and protein on this diet.

    If you're wondering can you drink alcohol on a keto diet, the answer is yes and no. Most alcohols are not keto-friendly but there are more options than you would think.  A trick is to look for what alcohol is gluten free which can often be an indicator they're also low in carbs.

    Note this: Not all fats are created equal. Avoid processed polyunsaturated fats and trans fats (which you’ll find abundantly in junk foods and substitutes like margarine).  If you've tried the diet before and found you were not losing weight on keto, some of these foods might be the problem.

    These fats are distinctly unhealthy, and since fats are the main category of nutrition in a Ketogenic diet, you’ll want to make their quality a top priority.

    Expanding our scope, here’s a non-exhaustive list of foods that are fantastic staples for any Keto diet and will help you hit macros:

    Foods to eat

    • Meat - Beef, poultry, lamb, fish, etc. Organic and grass-fed are always better!
    • Eggs
    • Vegetables - leafy greens like kale, lettuce, arugula; and above-ground veggies like broccoli, cauliflower, etc.
    • Nuts and seeds - Almonds, macadamias, sunflower seeds, etc.
    • Avocados and (some) berries - raspberries, blackberries, options that score low on the glycemic index
    • High-fat dairy - Full-fat cream, hard cheeses, butter, etc. 
    • Sweeteners - stevia, monk fruit, and other low-carb options
    • Other fat sources - like salad dressings, olive oil, MCT oil

    When you find good sources of these keto-friendly foods, consider buying in bulk to reduce your meal prep cost.  And here’s a list of foods you should avoid on a Ketogenic diet, as they’re high in carbs and other sugars:

    Foods to avoid

    • Grains - Wheat, corn, rice, cereal, pasta, etc.
    • Sugar - cane sugar, maple syrup, honey, agave, etc.
    • Fruit - Apples, bananas, kiwis, citrus, etc.
    • Tubers - potatoes, yams, carrots, jicama, etc.
    • Alcohol - rare exceptions are a glass of dry wine or unsweetened spirit. All other alcohols are not keto-friendly
    • Any processed foods

    What are net carbs?

    When you're considering what to eat on keto diet, you should know about net carbs per day. That's taking your total grams of carbs, and subtracting the grams that come from fiber, as our bodies don't process these the same way.

    For instance, if a serving of nuts contains 11 grams of carbs and 3 grams of fiber, your net total carbs are 8 grams!

    While this won’t make a huge difference in your dietary calculus (you still want to cut out essentially every carb you can), it can allow for a snack or additional ingredient in an otherwise carb-devoid meal.


    Keto Menu for Beginners

    Keto Diet Beginners

    You may be thinking that this all sounds restrictive but getting started on a keto diet menu for beginners is easier than you think.

    How do I go about this?

    Since most processed foods aren't an option, you may find yourself cooking at home more than you had before starting the keto diet.  

    Meal prepping can be a huge help.  Choosing the best day to meal prep each week to make meals and snacks can help avoid easy temptations when starting a new diet.

    Thankfully, keto recipes are abundant to make an eating plan for all different kinds of eaters: vegetarian keto diet options, gluten-free keto, paleo foods & foods in the paleo lifestyle, and more.

    But if cooking and meal prepping seems intimidating or you just don't have that kind of time, consider using a healthy meal delivery service.  These services can make getting started on the keto diet even easier by delivering professionally created low-carb meals.

    Here are three great options for Keto meals throughout a normal day:

    Like with alcohol, many gluten-free and paleo snacks are also low carb and keto-friendly but not all of them.  Make sure to still read the ingredients list to check for possible sources of carbs that aren't balanced out by fiber.

    What are the Benefits and Risks?

    The health benefits of ketosis are numerous

    Weight loss. 

    When your body enters a ketogenic state and starts burning body fat instead of sugar, the excess fat reserves on the body are used up to make energy and maintain ketone levels.

    When the body is burning glucose for energy, fat is mostly stored away. Ketosis taps into these fuel reserves.

    So, a proper state of ketosis can certainly help you lose weight.

    Blood sugar control. 

    As a result of the foods in a Keto diet, blood sugar is naturally decreased.

    Many diabetics or those at risk have benefitted from a Ketogenic diet, as insulin levels are regulated more effectively in a low-carb diet. Many people with type 2 diabetes have found their blood sugar levels are easier to maintain and control.

    Mental focus. 

    A key point of health and wellness, regulating blood sugar and increasing the healthy fatty acids in one’s diet has been shown to improve mental focus and stamina.

    Increased energy, normalized hunger. 

    Fat is a much better fuel source than sugar.

    By using fat for energy, adoptees have a higher and more consistent energy level, increased physical performance, and they feel satiated by their meals for longer.


    Like previously mentioned, Keto has shown significant therapeutic merit in treating epilepsy.

    Blood pressure and cholesterol. 

    A state of Ketosis has been shown to helpfully regulate these key health factors, decreasing the risk of heart disease.  Recent studies on keto and high blood pressure have found that the diet can help to lower blood pressure.

    Kevin's lettuce wrap

    There are some risks or side-effects to consider.

    Keto flu. 

    For example, your body’s shock at rapidly changing its nutritional intake can cause what is called the “Keto flu,” a series of flu-like symptoms which usually pass once the body adjusts.

    Kidney stones. 

    The increased animal product in the ketogenic diet may stress the kidneys, acidifying the urine and causing kidney stones.

    Less fiber. 

    Many of our typical carbs also carry necessary fiber. Without these sources, it may be necessary to augment the Ketogenic diet with a fiber supplement, or focus on foods like broccoli which are Keto-friendly and also rich in fiber!


    Studies have shown that, if care isn’t taken to balance the intake of important nutrients often excluded by Keto diets, deficiencies can occur, impacting bones, the heart, and other crucial health factors.

    It’s always a good idea to talk to your health provider or registered dietitian before embarking on the Ketogenic diet or any other diet.

    Do doctors recommend Keto?

    Many medically reviewed publications have explored the positives and negatives of keto diet. While there are certainly benefits, it's an ongoing conversation and the conclusions are not unanimous.

    Ultimate Keto Shopping List for Beginners

    So… what does a keto grocery list look like? 

    Next grocery trip, pick up these key items to jumpstart your keto diet!

    • Protein - grab chicken, beef, and fatty fish like wild salmon. Always organic, and don’t be afraid to get the fattier cuts of meat!
    • Eggs - also full of protein, and exceedingly versatile
    • Fats - avocado, coconut, and extra-virgin olive oils are wonderful plant-based sources of fats. Butter and Ghee are great options as well.
    • Vegetables - asparagus, avocado, broccoli, Brussel sprouts, cabbage
    • Fruit - raspberries, strawberries, watermelon
    • Greek yogurt - not low fat, go full and unsweetened!
    • Beverages - coffee, tea, sparkling water
    • Snack - cheese crisps, guacamole, jerky, nuts
    One problem you might run into while trying to start a new keto diet is your local grocery store not having the specialty ingredients you need to create delicious, keto-friendly meals.  You can order many ingredients online, including entire meals with a meal delivery service.


    The best meal delivery kits will have plenty of options for keto, paleo, gluten-free and beyond.  But sometimes the price can be a bit of a shock.  Some people wonder why meal delivery kits so expensive.  

    When considering meal kits by price, think about the ingredients you need for the meals you would like to make at home.  If some of those ingredients need to be ordered online anyway, that can quickly add up. 

    Meal kits are also known to significantly reduce food waste by only sending you what you need!

    One of the biggest benefits of meal kits is the expertise of a team of professional chefs and nutritionists who are creating meals specifically for the Keto diet.  The hours of research into ingredients is done for you!


      Remember that it takes time for the body to adjust to any dietary change. It can take a few days, or as long as a couple of weeks, for the metabolism to shift into ketosis. 

      And once it’s there, maintaining that state requires vigilance and dedication. If you’re going to try a Keto diet, be patient and persistent. Results won’t be instantaneous, but with the correct eating plan for you, health benefits and weight loss are within your grasp.
