What is the Keto Diet?

The ketogenic diet, also known as the keto diet, is an eating plan that focuses on low carb intake, moderate protein intake, and high fat intake. The goal of this diet is to put your body into a state of ketosis, where your body starts burning fat instead of carbs as its primary source of energy. Ketosis forces your body to burn fat stored there, leading to weight loss and improved overall metabolic health.

Keto Diet Foods

What's Allowed

The keto diet emphasizes foods rich in healthy fats and protein while limiting carbs. Protein sources such as meat (chicken, beef, pork), fish (i.e. salmon), eggs, low-carb vegetables, nuts, seeds, fats and oils, and dairy are allowed. Meat and fish  are the main sources of protein. Eggs are also a great choice because they are easy to prepare and packed with nutrients. Low-carb vegetables such as spinach, broccoli, cauliflower, and zucchini provide essential vitamins and minerals without the excess carbs. Healthy fats come from sources like nuts and seeds such as almonds, walnuts, and flaxseeds,  and oils such as olive oil, coconut oil, butter, and avocado, providing the energy base of the keto diet.

Foods to Avoid

Foods to strictly limit or avoid on the keto diet include those high in carbohydrates. This includes sugary foods and drinks (sweets, soda, fruit juice), grains (bread, pasta, rice, cereals), starchy vegetables (potatoes, corn), and most fruits. Sugar rapidly elevates blood sugar levels, hindering the body's ability to enter ketosis. While fruits are generally healthy, their natural sugar content can also interfere with ketosis. Berries can be enjoyed in moderation.

Sample Easy Meal Swap

Instead of a traditional dinner of chicken, potatoes, and salad, opt for baked chicken with roasted  zucchini and an avocado salad. It’s a simple swap that keeps the carbs low while still providing healthy fats and protein. The baked chicken is high in protein, the zucchini provides fiber and vitamins, and the avocado salad adds healthy fats that will help keep you energized, satisfied, and full longer.

Essential Rules of Keto Success

Low Carbs

On the keto diet, the goal is  to consume no more than 20-50 grams of carbs per day. For comparison the average American consumes more than 250 grams of carbohydrates per day. (McKinney and LDN)  Reducing your carbohydrate intake is key to inducing ketosis, the metabolic state where your body burns fat as its primary source of fuel. Low carb intake also helps stabilize blood sugar levels, which can lead to a better mood and increased energy.

Our Zenlightful Keto Wafer bars, with just 2-3 net carbs per bar are a delicious way to satisfy your cravings without disrupting your ketosis. To ensure these wafers truly support your keto journey, we partnered with Bartek Szemraj, certified clinical dietician from Poland where Zenlightful snacks are produced, and a big fan of the Zenlightful brand, to conduct blood glucose level tests before and after eating our wafer bar. The results? Enjoying a Zenlightful Keto Wafer bar does not cause a glucose spike, allowing you to savor the flavor without compromising your keto goals.  

Moderate Protein

While protein is essential to building and repairing tissues, it’s crucial to consume it in moderation on the keto diet. Excessive protein intake can be converted into glucose by the body, potentially hindering ketosis and prevent you from burning fat. Focus on healthy protein sources like meat, fish, and eggs, and consume them in appropriate amounts to support your keto goals. 

High Fat

Healthy fats become the primary energy source on the keto diet. Prioritize sources like olive oil, avocados, nuts and fatty fish like salmon. These fats provide sustained energy, helping to stabilize blood sugar levels and reduce cravings. By keeping you full and satisfied, healthy fat intake can contribute to reduced calorie intake and support weight loss goals. 

Staying Hydrated

Proper hydration is paramount on the keto diet. Adequate water intake helps prevent the “keto flu,” a temporary phase where some individuals experience side effects like fatigue and headache. It also plays a crucial role in maintaining electrolyte balance, which can be disrupted during ketosis. Water also aids in digestion and the efficient removal of toxins from the body. Drinking at least 8 glasses of water per day is recommended to stay hydrated and support metabolic processes.

Monitoring Progress

Tracking your progress is crucial for navigating the keto diet successfully, staying motivated, and making adjustments as needed. By diligently recording your daily food intake and noting how you feel, you can gain valuable insights into your body’s response to this dietary shift. For some, self check ins like regular weigh ins and measuring body circumference provides objective data on your progress. Activities like maintaining a food journal allows you to identify potential obstacles, such as hidden carbohydrate sources or frequent cravings, enabling you to make informed adjustments and optimize your keto journey for better results.

Keto Diet Effects

Weight Loss

One reason people choose the keto diet is weight loss. By reducing carbohydrate intake and increasing fat intake, the body starts burning stored fat. This effect is often quick and noticeable, which can be motivating for people looking to lose weight. 

Increased Energy Levels

Many people report an increase in energy on the keto diet, as fats are a more stable source of energy than carbs. Instead of experiencing fluctuating blood sugar levels that can lead to fatigue and lack of energy, people on the keto diet have consistent energy levels throughout the day. 

Improved Metabolic Health

The keto diet can help lower blood sugar levels and improve insulin sensitivity. This is especially beneficial for people with type 2 diabetes or insulin issues. Stabilizing blood sugar levels and improving insulin sensitivity can also lead to overall improvements in metabolic health.

Reduced Inflammation

The keto diet can help reduce inflammation in the body, which is beneficial for people with autoimmune diseases. Reducing inflammation can also lead to an improvement in overall well-being and quality of life.

Improved Heart Health

The keto diet can positively impact heart health by improving your lipid profile. By lowering triglycerides and increasing levels of “good” cholesterol (HDL), it can contribute to a healthier cardio vascular system.. Improving heart health can lead to a reduced risk of cardiovascular disease and improved overall health.

How to Get Started on the Keto Diet

Plan Meals

Meal planning is your keto diet success secret. By preparing in advance you minimize the risk of impulsive, non-keto choices and ensure consistent access to healthy options. Stock your kitchen with keto-friendly staples, plan your meals in advance to avoid impulsive choices, and consider batch cooking to streamline your week. This proactive approach minimizes temptations, ensures consistent access to healthy options, and ultimately increases your chances of long-term success on the keto diet. 

Beware of Hidden Carbs

Many processed foods contain hidden carbs, often in the form of added sugars. To avoid these pitfalls, carefully scrutinize food labels, opt for whole unprocessed food whenever possible, and create your own sauces using natural ingredients. Checking labels and making informed choices can help you minimize your intake of hidden carbohydrates and increase your chances of achieving and maintaining ketosis. 

Start Slowly

Abruptly switching to a keto diet can trigger the “keto flu,” characterized by fatigue, headaches, and nausea. To minimize these symptoms, gradually reduce your carbohydrate intake over several weeks. This gradual transition allows your body to adapt to its new energy source and minimizes the risk of experiencing unpleasant side effects. 

How to Avoid the Most Common Keto Diet Mistakes

Not Enough Fat

Keto diet beginners are often afraid to eat a lot of fat. Remember that healthy fat is the main source of energy on the keto diet. Eating enough fat is key to maintaining energy and achieving ketosis. Add more avocado, olive oil, and butter to your meals to increase your fat intake. Healthy fats also help keep you feeling full and prevent hunger pangs.

Difficulty Maintaining Electrolyte Balance

The keto diet can significantly reduce your body’s electrolyte levels, particularly sodium, potassium, and magnesium. Replenishing these minerals is crucial to prevent deficiencies, and  minimize the unpleasant symptoms of “keto flu,” such as fatigue and headaches. To increase sodium intake, consider adding salt to your meals or enjoying bone broth. Incorporate potassium rich foods like avocado and spinach (not bananas which are high in sugar), and magnesium-rich sources such as nuts and seeds, into your daily diet. By tracking your electrolyte replenishment, you can improve how you feel and enhance your overall experience on the keto diet. 

Changing Too Much at Once

As stated above, not starting slowly can cause unpleasant side effects like the “keto flu,” so to reduce the chances of feeling these symptoms, implement keto diet strategies such as strictly limiting carbs over a period of time.

Navigating the Keto Journey: Common Challenges and Solutions

Keto Flu

Keto flu is a set of symptoms, such as fatigue, headaches, and nausea, that can occur at the beginning of the keto diet. This is caused by the body adapting to a new energy source. Drink plenty of water, replenish electrolytes, and gradually reduce your carb intake to help alleviate keto flu symptoms. Consuming bone broth, which is rich in electrolytes, can help alleviate keto flu symptoms.

Keto Breath

Some people on the keto diet experience bad breath due to ketone production. This problem can be alleviated by drinking plenty of water, chewing sugar-free gum, and brushing your teeth regularly. Bad breath is usually temporary and should go away after a few weeks as your body fully adapts to ketosis.

Constipation

Constipation is a common problem on the keto diet due to low fiber intake. To prevent constipation, eat more low-carb vegetables like broccoli and spinach, and drink plenty of water to improve digestion. Adding flax or chia seeds to your diet can also help increase fiber intake and improve regularity.
