Keto Guide: Crash Course

Keto Guide: Crash Course

This keto guide covers everything from the types of ketogenic diets, what to eat and avoid, as well as the side effects or dangers of altering the daily intake of macronutrients. 

What is Keto? 

Keto is the shortened version of ketogenic. By following a keto meal plan, you will increase your fat intake while simultaneously decreasing your carbohydrates. The majority of your daily calories will come from protein and fat, causing a metabolic state of ketosis. 

A keto diet can be a terrific way to lose weight. With this plan, the body uses more calories to break down fat stores for energy when compared to what it takes when processing carbohydrates. Keto meal plans can also help minimize symptoms from some medical conditions, including heart disease, acne, and diabetes. 

What is Ketosis? 

The metabolic state of ketosis is when the body runs out of carbohydrates to burn for energy and uses fat stores instead. During this process, the body produces ketones that are effective to use for energy. 

Ketosis is an effective way to burn fat, but it can also help you feel less hungry and keep muscle mass. By consuming less than 50 grams of carbohydrates each day, the body will fall into a state of ketosis anywhere from three to four days. 

Types of Ketogenic Diets

When searching for a keto guide, it can be exhausting. There are different types of ketogenic diets that an individual can follow, each with its benefits and disadvantages. Some of the more popular versions include: 

  • Standard: Includes a high fat intake, moderate protein consumption, and limited carbohydrates 
  • Cyclical: Includes periods of a standard meal plan for five days, followed by two high carb days
  • Targeted: Allows a higher carbohydrate intake around extensive workouts or physical activities
  • High Protein: Increases the protein content, leaving less for fats and carbs

Although the keto diet is well-known for many reasons, it is the standard meal plan with has extensive studies. There is not much research on the alternatives that can provide facts and results from use. 

Foods to Eat

Many foods fit in well with the keto guide meal plan. 

Meat and Meat Alternatives

Meats, including beef, lamb, pork, chicken, and wild game, are terrific choices. There are some alternatives like tofu and tempeh that can align with a proper keto diet. 

Eggs, fish, and some seafood items can provide ample protein and include essential omega fatty acids that are part of a healthy diet. 

Vegetables and Fruits 

Not all vegetables align with this meal plan, though. Stick with leafy green vegetables, non-starch items, or anything that grows above ground. Small amounts of tart berries, lemons, limes, and coconut can be a treat. 

Nuts and Seeds 

While nuts and seeds are high in protein, they can also include hidden carbs. Some of the best nuts are almonds, pecans, peanuts, and walnuts. Sunflower and pumpkin seeds can give a protein boost while keeping daily carbs low. 


Cheese and greek yogurt are the best choices to add fat and protein. Stick to items that do not add flavorings or added sugar. 

Milk can be added to coffee or tea sparingly only.


Most of the fat content should come from food items consumed each day, but several oils and sauces fit the ketogenic diet. Olive oil, salad dressings, mayonnaise, and butter can be enjoyed and enhance the taste of a dish. 

Foods to Avoid 

Some food items will hinder the metabolic ketosis state and are not ideal for this meal plan.


Wheat flour, bread, pastries, and cereal contain high amounts of carbohydrates that do not align with this meal plan. Oats, pasta, rice, corn, and cornstarch should not be present. 

Starchy Vegetables 

White and sweet potatoes, yams, and parsnips contain a high amount of starch, inevitably providing the body with the glucose that will hinder a ketosis state. 

Beans and Lentils

Many types of beans and lentils are high in carbohydrates. Avoid soy, peas, chickpeas, beans, and lentils during this meal plan. 


Refined sugars and sweeteners are not part of a keto diet. Excess glucose will keep a body out of the state of ketosis. 

Milk and Alcohol

Using small amounts of milk products in coffee and tea is acceptable, but having a glass of milk should be avoided due to the sugar content. 

Alcohol is not in this meal plan. The body uses it for energy, and often alcohol is mixed with sugary drinks that are not allowed. 

Pros and Cons of Keto Diet 

With any change in diet, there are pros and cons. Knowing the benefits and disadvantages can help anyone determine if a ketosis meal plan is right for them. 


  • Weight loss
  • Regulate insulin levels

Macronutrient Breakdown for Keto Diet Meals

The variations of the keto diet will have corresponding macronutrient allowances. These breakdowns include: 

  • Standard Ketogenic Diet: Fats 70%, Protein 20%, Carbohydrates 10% 
  • High Protein Ketogenic Diet: Fats 60%, Protein 35%, Carbs 5%
  • Targeted and Cyclical Ketogenic Diets: Include increased amounts of carbohydrates up to 20%, depending on physical activity

How to Reach a State of Ketosis 

The state of ketosis is reached effectively after only three or four days by consistently reducing the number of carbohydrates and refined sugars from the daily intake. Lowering the volume between 20 to 50 grams will help reach this metabolic state. 

Increasing physical activity can also help jumpstart ketosis, as the body will need to burn more fuel for energy. Without the addition of carbs, ketones are produced, falling into a ketosis state. 

Dangers of Keto Diet

One side effect of the keto diet is known as the keto flu. Symptoms are similar to having a flu virus, including headaches, stomach upset, vomiting, or sore muscles. These side effects can happen as the body enters a state of ketosis.
