The Ketogenic Diet: An Ultimate Guide to Keto

Eggs, Meat, and Poultry

You can include all meat and poultry in a keto plan– preferably a wide variety of cuts, including bone-in meats.


Bacon Beef – all cuts
Chicken Duck
Eggs Fermented Meats (prosciutto, salami)
Ham Lamb
Mutton Pork
Turkey Venison and wild game

Fats and Oils

ketogenic-fats-and-oils

While any fat is technically suitable for a ketogenic diet, it’s better to avoid industrial vegetable oils.

Here are some healthy fat sources:

Avocado Oil Butter
Coconut Oil Extra Virgin Olive Oil
Ghee Goose Fat
Lard Macadamia Nut Oil
Red Palm Oil Tallow

Fish

There are countless edible fish and here are some of the commonly available ones.

Anchovy* Bream
Carp Catfish*
Cod Flounder
Haddock Halibut
Herring* Mackerel*
Sardines* Salmon*
Swordfish** Tilapia*
Trout* Tuna**

*Best sources of omega-3  **High in both omega-3 and mercury

Fruit (low sugar)

ketogenic-diet-low-sugar-fruit

Since ketogenic diets require carbohydrate intake to be very low, most fruits are unsuitable.

However, there are plenty of low sugar fruits that are perfectly fine in moderation.

Avocado Blackberries
Blueberries Boysenberries
Coconut Cranberries
Lemon Lime
Olives Raspberry
Rhubarb Salmonberry
Strawberry Tomato

There are also many different types of berries which are okay in moderation.

Nuts

ketogenic-diet-nuts

Most nuts are great for a ketogenic diet, but cashews, chestnuts, and pistachios are too high in carbohydrate.

Nuts are very energy-dense, so a handful should be enough (1 ounce/28grams)

Here are the best low-carb choices:

Almonds Brazil Nuts
Hazelnuts Macadamia
Peanuts Pecan
Pine Nuts Walnuts

Seeds

Personally, I’m not a fan, but seeds are also a reasonably nutritious option.

Aim for about a handful / 1 ounce / 28 grams.

Chia Seeds Flaxseeds
Hemp Seeds Pumpkin Seeds
Sesame Seeds Sunflower Seeds

Shellfish and Seafood

Abalone Clams
Cockles Crab
Eel Lobster
Mussels Oysters
Shrimp Scallops
Sea Squirt Squid

Vegetables

Generally speaking, lower carb veggies should be the focus: cruciferous veg and leafy greens.

The plants that grow above ground have the lowest carb count, while vegetables growing underground tend to have more.

However, a small amount of below-ground vegetables should be okay if you factor them into your total carb count.

Artichoke Asparagus
Beet Greens Bell Peppers
Bok Choy Brocolli
Brussels Sprouts Cabbage
Cauliflower Celery
Chives Cucumber
Eggplant Green Beans
Green Onion Kale
Kohlrabi Leek
Lettuce Mushrooms
Radish Red Cabbage
Rutabaga Seaweed
Spaghetti Squash Spinach
Swiss Chard Tomato
Turnip Zucchini

Key Point: As shown above, ketogenic diets might restrict some foods — but there is still a great deal of choice.

Snack Ideas

ketogenic-diet-snack-ideas

In addition to the above food groups, there are a number of convenient snacks which are suitable for keto.

Here’s a list to give you a few ideas:

  • Berries and cream: Your choice of berries in a bowl with some heavy cream.
  • Boiled eggs: If you have any feelings of hunger, a few boiled eggs does a great thing for satiety.
  • Celery with cream cheese: Spread some cream cheese on a few stalks of celery for some nutrients and fat-soluble vitamins.
  • Cheese and Prosciutto: If you’re craving some finger-food, then cheese and prosciutto is an excellent option. Add a glass of red wine if you like.
  • Dark chocolate: 85% minimum.
  • Guacamole salad: Mash some guacamole and add in your ingredients of choice.
  • Keto milkshake: blend some coconut milk alongside some cacao and a natural sweetener such as erythritol. Another good option is to use fresh berries for a fruit milkshake.
  • Mozzarella sticks: The website ‘Healthful Pursuit’ has some delicious looking mozzarella sticks made with almond flour.
  • Pork rinds: Crispy pork goodness that you can easily make at home.
Key Point: A ketogenic diet doesn’t only mean meat and vegetables. There are also dozens of tasty snacks you can make.

Foods to Avoid 

foods-to-avoid-on-keto

Due to the nature of the ketogenic diet, carbohydrate content in food should be low — ideally below about 5% or so.

Therefore, you need to restrict grains, starches, sugars and high-carb plant foods.

Below you can see a list of foods to avoid if you want to achieve ketosis:

  • Beer
  • Cakes
  • Cookies
  • Cereals
  • Dried fruit (a slight amount is OK, but best avoided)
  • Fruits high in carbs (banana, mango, papaya, etc.)
  • Fruit juice
  • Grains (bread, oats, pasta, rice, etc.)
  • Legumes
  • Low-fat processed foods
  • Milk (a very small amount is OK)
  • Sugary foods in general
  • Sweet wines/sugary alcohol in general
  • Tubers such as parsnips, potatoes, and sweet potatoes

And these foods are technically ‘ketogenic,’ but it’s better to avoid them for health:

  • Low-carb processed foods: they may be low-carb, but they’re usually full of additives.
  • Margarine
  • Vegetable oils

Not ready to give up alcohol?

If you like drinking from time to time, then that is no problem – there are many low carb alcohol drinks out there.

Spirits and dry red wine are two of the best choices.

Keto versions of high-carb foods

While it’s better to stick with nutrient-dense foods like meat, fish, and vegetables, many people like a treat from time to time.

And if you want to be ‘keto’ yet still have a pizza, some bread, or even a piece of cake – it’s possible.

There are many delicious low-carb recipes available for all of these things, and there are hundreds on Pinterest.

A Basic Ketogenic Meal Plan

Not sure on how you can put some meals together?

Here are some breakfast, lunch, and dinner ideas for every day of the week.

Breakfast

keto-breakfasts

  • Bacon and Eggs: Several slices of bacon, some fried eggs, mushrooms, and a grilled tomato.
  • Mackerel: A baked or steamed fillet of mackerel with some leafy greens sauteed in butter.
  • Crustless Quiche: A crustless quiche recipe is an easy breakfast that also tastes delicious. Bacon and cheese make a great flavor combination.
  • Omelet: A cheese and vegetable omelet using your favorite veggies.
  • Boiled Eggs: Several boiled eggs, some cheese, and an avocado.
  • Scrambled Eggs: Scrambled eggs with some meat and veggies of your choice.
  • Ham, egg and cheese melt: A ham, melted cheese, and egg sandwich. While bread isn’t keto-friendly, you can use a low-carb bread recipe such as cloud bread.

Lunch

keto-lunch

  • Chicken Salad: Diced chicken, salad greens, cherry tomatoes, balsamic vinegar, and extra virgin olive oil.
  • Finger Food: A handful of nuts, slices of cheese, and some berries.
  • Cloud Bread Sandwich: A ham, cheese, and salad cloud bread roll.
  • Chicken Soup: Chicken, stock, some cream, pepper, salt, and mushrooms. And if you want to eat it hot in the office, then it’s possible if you use a mini portable oven.
  • Zoodle Carbonara: First, you need some zoodles, and then add cream, ham, egg, and seasonings. Tastes better warm!
  • Beef and Tomato Soup: Simmer beef, onion, diced tomatoes, mushrooms, and herbs of your choice for about 1 hour. This meal can be reheated later if eating away from home.
  • Low Carb Sushi Roll: Instead of using rice in the nori wraps, use cream cheese instead. Then add some sashimi of your choice (salmon tastes good!).

Dinner

keto-dinner

  • Pork Chops: A pork chop cooked with onion and garlic, and some buttered asparagus.
  • Cream Salmon: A fillet salmon covered in coconut cream cheese sauce, with some broccoli and mushrooms.
  • Steak: A piece of steak with mushrooms, garlic, and green beans.
  • Frittata: A cheese, mushroom and vegetable frittata.
  • Sausages: Some (real meat) sausages, alongside some mashed rutabaga with butter and sauteed garlic and onions.
  • Chicken Curry: Curries are a great meal for ketogenic diets because they are mainly fat and protein. All you have to do is skip the rice.
  • Low Carb Pizza: Make a fathead pizza; it tastes great, and it’s reasonably healthy.

Keto-Friendly Restaurants

For keto on the go, then look for any meat-based restaurants.

A steak or piece of meat/fish along with some vegetables is suitable, and you can find restaurants offering this almost everywhere.

Possible Dangers 

dangers-of-ketogenic-diets

There are two possible things to mention here, and these are ketoacidosis and hypoglycemia.

Ketoacidosis

Firstly, there is a lot of fearmongering about ketoacidosis and ketogenic diets.

Generally, this comes from people who don’t know the difference between ‘ketosis’ and ‘ketoacidosis.’

As previously mentioned, ketosis is a natural state in which the body starts to burn ketones (fats) for energy instead of glucose.

In contrast, ketoacidosis is a potentially life-threatening condition when the body doesn’t make enough insulin and ketone levels become abnormally high.

However, in low carb diets, the production of ketones is “regulated, controlled, and harmless”.

The condition is otherwise known as diabetic ketoacidosis (DKA), and usually, results from poor management of type 1 diabetes which can lead to dangerous ketone levels.

It’s very unlikely for a healthy person who produces sufficient insulin to experience ketoacidosis.

However, if you suffer from diabetes then always consult your doctor and conduct thorough research before a dietary change.

Hypoglycemia

When first beginning a ketogenic diet, experiencing hypoglycemia (low blood sugar) is a possibility.

With this in mind, it’s important to know exactly why it occurs and how to avoid it:

  • Hypoglycemia happens when blood sugar levels drop to extremely low concentrations (approx: <70mg/dl) and it can cause fatigue, lightheadedness, and dizziness.
  • It can occur when suddenly going from a high-carbohydrate diet to very low carb.
  • One reason is because of a huge drop in blood sugar levels in people who are used to having higher blood sugar.
  • Hypoglycemia is a lot more common in people with diabetes or a certain degree of insulin resistance.

The Solution

While some suggest the solution is to raise blood sugar by eating some sugary food, I think that is ill-advised.

Here’s why:

  • As hypoglycemia usually occurs from high to low blood sugar swings, then all this does is make your blood sugar high again. And then the cycle continues.
  • The key to getting past this is to reduce high blood sugar permanently, and a ketogenic diet can help in this regard.

In the initial stages of a ketogenic diet, it may be helpful to eat regularly rather than fasting for extended periods of time.

Hypoglycemia can be dangerous, so if you are experiencing it, then it may be worth consulting a low-carb friendly doctor.

And this is especially the case if you have diabetes; for any medical issues, it’s better to be safe than sorry.

Key Point: Potentially dangerous conditions such as ketoacidosis and hypoglycemia are possible for diabetics if care isn’t taken. People with diabetes should consult a doctor before making large changes to their diet.

Side Effects of Ketosis (and How to Solve Them)

Being in ketosis can also cause several minor side effects, so if you have just started a ketogenic diet then look out for the following:

Alcohol Tolerance

Many people report lower tolerance of alcohol on a ketogenic diet, sometimes dramatically so.

Solution: Firstly, don’t drink too much or on an empty stomach. And if you’re just starting keto, then carefully monitor how you feel when you drink.

Bad Breath

When the body enters ketosis and starts burning fat (ketones), chemicals in the breath such as acetone may cause bad breath.

Solution: Waiting; for many people, this bad breath only lasts for the first week or two of a ketogenic diet. While it persists, you can use breath fresheners to hide the scent.

Constipation

Some people may develop constipation on keto. Many people blame a lack of fiber for this, although, in truth, both too little and too much fiber could be an issue depending on the individual.

Solution: First of all, constipation usually isn’t the result of not eating fiber – the cause is usually something you are eating.

For example, many people have sensitivities regarding certain foods such as dairy, eggs, and nuts. Or maybe you are overdoing it on one of these foods.

Either way, if you have recently increased intake of one of these foods, then experiment to see what may be causing the problem.

If you can’t find any dietary reason, then increasing intake of leafy green vegetables may help.

Cramps, Fatigue, Induction Flu, and Low Energy

People new to keto often experience cramps, particularly in the legs and feet. Additionally, many people feel fatigue, tiredness, and low energy.

Solution: These symptoms are usually the result of an electrolyte imbalance, especially concerning magnesium, potassium, and sodium.

Don’t worry because it is common in the early stages of ketosis, due to the body releasing significant amounts of water (and salt) as carbohydrate intake (and insulin) drops.

Make sure you are getting enough of these micronutrients. There are also greater needs for sodium on a ketogenic diet, so increase salt intake by liberally salting your food.

Heart Palpitations

Heart palpitations are another typical side effect in the first few weeks of a ketogenic diet. The palpitations could be due to mild dehydration or an electrolyte imbalance.

Solution: Drinking more water to ensure adequate hydration, and increasing salt, magnesium, and potassium intake usually eases heart palpitations.

However, as the cause can be any number of issues, then see a doctor if you want to make sure. 

Key Point: There are various potential side effects when starting a low-carb diet. Despite this, most are temporary, and you can avoid them through a well-implemented diet with sufficient electrolytes.

Final Thoughts

There’s no perfect way of eating that fits everybody’s lifestyle and personal circumstance.

However, keto is a healthy dietary system that focuses on real, nutrient-dense foods.

But just one caveat:

Due to the potential side effects, make sure you research how to implement the diet successfully before you start.

If you follow a well-implemented ketogenic diet, then weight loss, better energy levels, and improved health markers are very common.
