Keto Diet What To Eat
The Ketogenic way of eating is the most ancestrally appropriate way a human can eat. It is also the most powerful diet for reversing diabetes and many other chronic diseases.
The ketogenic diet (or keto diet, for short) is a low-carb, high-fat diet that offers many health benefits.
In fact, over 20 studies show that this type of diet can help you lose weight and improve your health.
Ketogenic diets may even have benefits against epilepsy, diabetes, cancer, and Alzheimer's disease.
Learn What to Eat When on a Keto Diet
Below is a detailed basic guide to the Keto diet.
What Is a Ketogenic Diet
The ketogenic diet is a very low-carb, high-fat diet that shares many similarities with the Atkins and low-carb diets.
It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.
When this happens, your body becomes fabulously efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.
Ketogenic diets can cause massive reductions in blood sugar and insulin levels. This, along with the increased ketones, has diverse health benefits.
SUMMARY: The keto diet is a low-carb, high-fat diet. It lowers blood sugar and insulin levels and shifts the body’s metabolism away from carbs and towards fat and ketones.
Different Types of Ketogenic Diets
There are several versions of the ketogenic diet, including:
The cyclical ketogenic diet (CKD): This diet involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
The standard ketogenic diet (SKD): This is a very low-carb, moderate-protein, and high-fat diet. It typically contains 75% fat, 20% protein, and only 5% carbs.
The targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.
High-protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more. The ratio is often 60% fat, 35% protein, and 5% carbs.
Only the standard and high-protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.
The information in this article mostly applies to the standard ketogenic diet (SKD), although many of the same principles also apply to the other versions.
SUMMARY: There are several versions of the keto diet. The standard (SKD) version is the most researched and most recommended.
How Ketogenic Diets Will Help You Lose Weight
The ketogenic diet is an effective way to lose weight and lower risk factors for disease.
In fact, research shows that the ketogenic diet is far superior to the often recommended a low-fat-diet.
What's more, the diet is so filling that you can lose weight without counting calories or tracking your food intake.
One study found that people on a ketogenic diet lost 2.2 times more weight than those on a calorie-restricted low-fat diet. Triglyceride and HDL cholesterol levels also improved.
Another study found that people on the ketogenic diet lost 3 times more weight than those on the diet recommended by Diabetes UK.
The increased ketones, lower blood sugar levels, and improved insulin sensitivity may also play a key role.
SUMMARY: The ketogenic diet can help you lose much more weight than a low-fat diet. This often happens without hunger.
The Ketogenic Diet for Diabetes and Prediabetes
Diabetes is characterized by changes in metabolism, high blood sugar, and impaired insulin function.
The ketogenic diet can help you lose excess fat, which is closely linked to type 2 diabetes, prediabetes, and metabolic syndrome.
One study found that the ketogenic diet improved insulin sensitivity by a whopping 75%.
Another study in people with type 2 diabetes found that 7 of the 21 participants were able to stop using all diabetes medications.
In yet another study, the ketogenic group lost 24.4 pounds (11.1 kg), compared to 15.2 pounds (6.9 kg) in the higher-carb group. This is an important benefit when considering the link between weight and type 2 diabetes.
Additionally, 95.2% of the ketogenic group was also able to stop or reduce diabetes medication, compared to 62% in the higher-carb group.
SUMMARY: The ketogenic diet can boost insulin sensitivity and cause fat loss, leading to significant health benefits for people with type 2 diabetes or prediabetes.
Other Health Benefits of The Keto Diet
The ketogenic diet actually originated as a tool for treating neurological conditions such as epilepsy.
Studies have now shown that the diet can have benefits for a wide variety of different health conditions:
Heart disease: The ketogenic diet can improve risk factors like body fat, HDL cholesterol levels, blood pressure, and blood sugar.
Cancer: The diet is currently being used to treat several types of cancer and slow tumor growth.
Alzheimer's disease: The keto diet may reduce symptoms of Alzheimer's disease and slow its progression.
Epilepsy: Research has shown that the ketogenic diet can cause massive reductions in seizures in epileptic children.
Parkinson's disease: One study found that the diet helped improve symptoms of Parkinson's disease.
Polycystic ovary syndrome: The ketogenic diet can help reduce insulin levels, which may play a key role in polycystic ovary syndrome.
Brain injuries: One animal study found that the diet can reduce concussions and aid recovery after brain injury.
Acne: Lower insulin levels and eating less sugar or processed foods may help improve acne.
SUMMARY: A ketogenic diet may provide many health benefits, especially with metabolic, neurological, or insulin-related diseases.
Foods to Avoid When on Keto Diet
Any food that is high in carbs should be avoided.
Here is a list of foods that need to be reduced or eliminated on a ketogenic diet:
Sugary foods: Soda, fruit juice, smoothies, cake, ice cream, candy, etc.

Unhealthy fats: Limit your intake of processed vegetable oils, mayonnaise, etc.
Alcohol: Due to their carb content, many alcoholic beverages can throw you out of ketosis.
Sugar-free diet foods: These are often high in sugar alcohols, which can affect ketone levels in some cases. These foods also tend to be highly processed.
SUMMARY: Avoid carb-based foods like grains, sugars, legumes, rice, potatoes, candy, juice, and even most fruits.

Side Effects of The Keto Diet and How to Minimize Them.
Although the ketogenic diet is safe for healthy people, there may be some initial side effects while your body adapts.
This is often referred to as the keto-flu and is usually over within a few days.
Keto-flu includes poor energy and mental function, increased hunger, sleep issues, nausea, digestive discomfort, and decreased exercise performance.
To minimize this, you can try a regular low-carb diet for the first few weeks. This may teach your body to burn more fat before you completely eliminate carbs.
A ketogenic diet can also change the water and mineral balance of your body, so adding extra salt to your meals or taking mineral supplements can help.
For minerals, try taking 3,000–4,000 mg of sodium, 1,000 mg of potassium, and 300 mg of magnesium per day to minimize side effects.
At least, in the beginning, it is important to eat until you’re full and avoid restricting calories too much. Usually, a ketogenic diet causes weight loss without intentional calorie restriction.
SUMMARY: Many of the side effects of starting a ketogenic diet can be limited. Easing into the diet and taking mineral supplements can help.
Supplements for a Ketogenic Diet
Although no supplements are required, some can be useful.
MCT oil: Added to drinks or yogurt, MCT oil provides energy and helps increase ketone levels.
Minerals: Added salt and other minerals can be important when starting out due to shifts in water and mineral balance.
Caffeine can have benefits for energy, fat loss, and performance.
Exogenous ketones: This supplement may help raise the body's ketone levels.
Creatine provides numerous benefits for health and performance. This can help if you are combining a ketogenic diet with exercise.
SUMMARY: Certain supplements can be beneficial on a ketogenic diet. These include exogenous ketones, MCT oil, and minerals.
Frequently Asked Questions
Here are answers to some of the most common questions about the ketogenic diet.
Can I Ever Eat Carbs Again?
Yes. However, it is important to significantly reduce your carb intake initially. After the first 2–3 months, you can eat carbs on special occasions — just return to the diet immediately after.
Will I Lose Muscle on a Keto Diet?
There is a risk of losing some muscle on any diet. However, the high protein intake and high ketone levels may help minimize muscle loss, especially if you lift weights.
Can I Build Muscles on a Ketogenic Diet?
Yes, but it may not work as well as on a moderate-carb diet.
Do I Need to Refeed or Carb Load?
No. However, a few higher-calorie days may be beneficial every now and then.
How Much Protein Can I Eat on a Keto Diet?
Protein should be moderate, as a very high intake can spike insulin levels and lower ketones. Around 35% of the total calorie intake is probably the upper limit.
What if I Am Constantly Tired, Weak, or Fatigued?
You may not be in full ketosis or be utilizing fats and ketones efficiently. To counter this, lower your carb intake and re-visit the points above. A supplement like MCT oil or ketones may also help.
My Urine Smells Fruity on Keto, Why is This?
Don't be alarmed. This is simply due to the excretion of by-products created during ketosis.
My Breath Smells. What Can I Do?
This is a common side effect. Try drinking naturally flavored water or chewing sugar-free gum.
I Heard Ketosis Is Extremely Dangerous. Is This True?
People often confuse ketosis with ketoacidosis. The former is natural, while the latter only occurs in uncontrolled diabetes.
Ketoacidosis is dangerous, but the ketosis on a ketogenic diet is perfectly normal and healthy.
I Have Digestion Issues And Diarrhea. What Can I Do?
This common side effect usually passes after 3–4 weeks. If it persists, try eating more high-fiber veggies. Magnesium supplements can also help with constipation.
A Ketogenic Diet Is a Great Diet!
A ketogenic diet can be great for people who are overweight, diabetic, or looking to improve their metabolic health.
And, as with any diet, it will only work if you are consistent and stick with it in the long term.
Few things are as well proven in nutrition as the powerful health and weight loss benefits of a ketogenic diet.
