Keto Fundamentals
Many of the same characteristics can be found in the ketogenic diet, which is a very low carbohydrate, high fat diet that shares many similarities with the Atkins and low-carb diets.
It entails lowering carbohydrates and replacing them with fat. Your body enters a metabolic state known as ketosis as a result of this decrease in carbohydrates.
When this occurs, your body's ability to burn fat for energy becomes exceptionally strong. It also converts fat to ketones in the liver, which can be used as an energy source for the brain.
Blood sugar and insulin levels can drop significantly while eating a ketogenic diet. This, together with the increased ketones, has a number of health advantages.
Different Types of Ketogenic Diets
There are numerous forms of the ketogenic diet, including:
- Standard ketogenic diet (SKD): This is a low-carb, high-protein diet that is moderate in carbohydrates. It's made up of 70% fat, 20% protein, and 10% carbs.
- Cyclical ketogenic diet (CKD): This diet consists of several higher carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
- Targeted ketogenic diet (TKD): You can add carbs throughout your workouts on this diet.
- High protein ketogenic diet: This is a similar ketogenic diet to the one described above, however it contains greater protein. The proportion of fat, protein, and carbohydrates is usually 60%/35%/5%, although this varies based on individual requirements..
The only two types of ketogenic diets that have been studied extensively are the standard and high protein versions. Bodybuilders or athletes may use cyclical or targeted ketogenic diets, which are more advanced strategies.
The content in this article is mostly relevant to the traditional ketogenic diet (SKD), although many of the same ideas also apply to other versions.
What is Ketosis, And How Does it Work?
Ketosis is a metabolic condition in which your body burns fat rather than carbohydrates.
When you drastically reduce your carbohydrate intake, restricting your body's supply of glucose (sugar), which is the cells' main energy source, this condition occurs.
The most effective way to get into ketosis is to follow a ketogenic diet. Typically, this entails restricting carb intake to around 20 to 50 grams per day and eating plenty of fat, such as meat, fish, eggs, nuts, and healthy oils.
It's also critical to keep an eye on your protein intake. Protein may be converted into glucose if taken in massive amounts, which might delay your shift into ketosis.
Intermittent fasting may also assist you get into ketosis faster. There are many various types of intermittent fasting, but the most popular is limiting food intake to less than 8 hours per day and fasting for the remaining 16 hours.
You can measure the amount of ketones your body produces with blood, urine, and breath tests. This can tell you if you have entered ketosis.
You may know you've entered ketosis if you experience increased thirst, dry mouth, frequent urination, and decreased hunger or appetite.
A Ketogenic Diet Might Help You Reduce Weight
A ketogenic diet is a way to lose weight and improve your health.
A study showed that the ketogenic diet may be just as effective as a low-fat diet for weight loss.
What's more, the diet is so filling that you can lose weight without counting calories or tracking your food intake.
According to a meta-analysis of 13 studies, following a very low carb, ketogenic diet was somewhat more efficient in terms of long-term weight reduction than a low fat diet. People who followed the keto diet lost more weight on average than people who followed a low-fat diet.
Furthermore, it resulted in decreased diastolic blood pressure and triglyceride levels.
In a study of 34 older people, those who ate a ketogenic diet for 8 weeks lost almost five times as much total body fat as those who ate a low-fat plan.
These changes may help to improve blood sugar levels and insulin sensitivity.
Ketogenic Diets For Diabetes And Prediabetes
Diabetes is a condition that affects how your body uses energy. People with diabetes often have high blood sugar levels, and their bodies may not be able to use insulin properly.
The ketogenic diet may assist you in reducing fat from your body, which is linked to type 2 diabetes, pre-diabetes, and metabolic syndrome.
Another older research discovered that the ketogenic diet improved insulin sensitivity by a staggering 75%.
A modest evaluation in women with type 2 diabetes revealed that a ketogenic diet for 90 days resulted in significant decreases in hemoglobin A1C, which is a biomarker of long-term blood sugar control.
According to a recent study of 349 individuals with type 2 diabetes, those who followed a ketogenic diet lost 26.2 pounds (11.9 kg) over two years. This is an important advantage when considering the relationship between weight and type 2 diabetes.
Participants who took part in the studies also reported a better blood sugar control and decreased need for certain blood sugar drugs throughout the study.
Other Advantages of a Ketogenic Diet
People have been using the ketogenic diet to improve their health for many years. The ketogenic diet is especially helpful for people with diseases that affect their metabolism, nervous system, or insulin levels.
The ketogenic diet has been studied and shown to help with a variety of common health problems, according to studies:
- Heart disease. The ketogenic diet may aid in the following risk factors: body fat, HDL (good) cholesterol levels, blood pressure, and blood sugar.
- Cancer. Because it may aid in slowing tumor development, the diet is now being investigated as a supplement to cancer therapy.
- Alzheimer’s disease. The keto diet appears to have neuroprotective effects and may help slow the progression of Alzheimer's disease.
- Epilepsy. The ketogenic diet can help epileptic children live a normal life by reducing their seizures.
- Parkinson’s disease. Another study revealed that the diet helped to alleviate Parkinson's disease symptoms.
- Polycystic ovary syndrome. The ketogenic diet might aid in the management of insulin levels, which are known to be involved with polycystic ovary syndrome.
- Brain injuries. The diet, in some cases, appears to help survivors of severe brain trauma.

Tips And Techniques For The Keto Diet
Getting started on the ketogenic diet might be difficult, but there are a few pointers and methods that may help you.
- Begin by learning how to read food labels and calculate the grams of fat, carbohydrates, and fiber in your favorite meals to see whether they fit into your diet.
- Planning your meals ahead of time might also be useful and save you time throughout the week.

- When you don't have much time, look into healthy frozen keto meals.
- When attending social events or seeing relatives and friends, you may want to consider bringing your own food, which can make it a lot easier to resist hunger and stick to your diet.
Tips For Dining Out While on a Ketogenic Diet
Many meals at restaurants may be modified to be ketogenic.
Many restaurants have meat or fish-based dishes on the menu. Replace any high carb food with extra veggies to enjoy this and other delicious meals.
Some other good meal options include omelets and eggs with bacon.
Another popular choice is burgers without buns. You may also try substituting the fries for vegetables instead. Add extra avocado, cheese, or bacon if desired.
Any kind of meat with extra cheese, guacamole, salsa, and sour cream may be ordered at Mexican restaurants.
For dessert, try a mixed cheese tray or berries with cream.
Choose a meat, fish, or egg-based meal when dining out. Instead of carbohydrates or starches, order extra veggies.
Side Effects And How to Prevent Them
The ketogenic diet, on the other hand, is generally safe for most healthy individuals. Although your body will adjust quickly, there may be some early symptoms while it does so.
There's a lot of anecdotal evidence that the keto flu is real. It generally lasts for a few days, according to reports from some people on the diet.
Diarrhea, constipation, and vomiting are all possible symptoms of the keto flu. Other uncommon complaints include:
- poor energy and mental function
- increased hunger
- sleep issues
- nausea
- digestive discomfort
- decreased exercise performance
To avoid this, you may try a standard low-carb diet for the first few weeks. This might teach your body to burn fat before you fully prohibit carbs.
Adding extra salt to your meals or taking mineral supplements may help you maintain a healthy water and mineral balance while on a ketogenic diet. Consult your doctor about your nutritional requirements.
It's critical to eat until you're full and to avoid restricting calories too much at first. A ketogenic diet is typically associated with weight loss as a result of lack of deliberate calorie restriction.
Many of the negative effects of starting a ketogenic diet can be reduced. Mineral supplements and lowering the intake of carbohydrates can aid in this process.
The Keto Diet's Drawbacks
In the long run, following a ketogenic diet may have some drawbacks, including the risks of the following:
- low blood protein
- too much fat in the liver
- kidney stones
- micronutrient deficiencies
Sodium-glucose cotransporter 2 (SGLT2) inhibitors for type 2 diabetes can raise the risk of diabetic ketoacidosis, a potentially fatal condition in which blood acidity rises. It is suggested that individuals who are taking this medicine should avoid the ketogenic diet.
Although a lot more study is needed to assess the long-term safety of the keto diet, several studies have shown that it is safe for most people. To help you make better decisions, inform your doctor about your diet.
Keto-Friendly Supplements
Although no supplements are required, some can be useful.
- Creatine. Creatine has a wide range of health and performance benefits. If you're doing a ketogenic diet while also exercising, this can assist.
- Caffeine. Caffeine has been shown to increase energy, fat loss, and performance.
- Minerals. When beginning, the addition of salt and other minerals may be essential due to changes in water and mineral balance.
- MCT oil. MCT oil can be added to beverages or yogurt and provides energy while also aiding in the development of ketone bodies.
- Whey. You can increase your daily protein intake by adding half a scoop of whey protein to shakes or yogurt.
- Exogenous ketones. This supplement is designed to help the body's ketone levels improve.
On a Final Note
People that have diabetes, are overweight, and want to enhance their metabolic health could benefit from a ketogenic diet.
It could be a poor fit for professional athletes or individuals who want to add a lot of muscle or weight.
It may not be reasonable to everyone's lifestyles and preferences. Consult with your doctor about your eating strategy and objectives to see if a keto diet is right for you.
Frequently Asked Questions
1. Is it possible for me to eat carbohydrates again?
Yes. However, it is critical to start out with a big carb reduction. You can have carbohydrates on special occasions after the first two to three months; simply resume your diet immediately afterward.
2. Am I going to have a muscle loss?
There's a danger of losing muscle on every diet. Protein intake and high ketone levels, on the other hand, might aid in the protection of muscle loss, especially if you lift weights.
3. Is it possible to gain muscle on a ketogenic diet?
Yes, and it may not be as effective on a low-carb diet.
4. How much protein may I consume?
Protein intake should be kept at a reasonable level since too much of it can raise insulin levels and decrease ketones. It's unlikely that more than 35% of your total energy consumption should come from protein.
5. What if I'm always exhausted, weak, or weary?
You may not be in complete ketosis, or your fat and ketone utilization might be sub-optimal. Try lowering your carb intake and reviewing the advice above to improve this situation. A supplement like MCT oil or ketones might also assist you.
6. I have a fruity-smelling urine. What is causing this?
Don't be concerned. This is simply because ketosis causes the body to excrete by-products.
7. My breath stinks. What can I do about it?
This is a common adverse effect. Try drinking water with no flavor or chewing sugar-free gum to alleviate the discomfort.
8. Is it true that ketosis is extremely hazardous? Is this something I should be concerned about?
Many people are perplexed by the terms ketosis and ketoacidosis. Although ketoacidosis is dangerous, a ketogenic diet typically produces safe levels of ketosis in healthy individuals. Before beginning any new diet, consult your doctor.
9. I have digestion problems and loose my appetite frequently. What can I do to regain my hunger?
This common side effect usually goes away after 3 to 4 weeks. If it doesn't go away, try eating more high fiber vegetables.
