A ketogenic diet (KD) is also known as a low-carb diet that enables the body to produce ketones, particularly in the liver that can be utilized as energy.
A review that was published in 2014 showed that this diet plan is supported by the biochemical and physiological basis that can induce weight loss effectively (1).
Here we will provide a basic overview of the KD, a sample meal plan and tips for getting started.
What is Ketogenic Diet?
The ketogenic diet or keto diet is a low-carbohydrate, high-fat diet that forces the body to burn fat instead of carbohydrates for energy.
This is achieved by drastically reducing carbohydrate intake and replacing it with fat. When this happens, the body enters a metabolic state called ketosis.
Research conducted at the Johns Hopkins Medical Center has shown that fasting for long periods can help reduce the frequency of seizure attacks.
According to the NCI, this diet is high in fat and low in carbohydrates (sugars), which cause the body to break down fat into molecules called ketones.
In ketosis, the liver produces ketones, molecules that the brain and other organs can use for energy. Ketosis has several health benefits, including weight loss, reduced blood sugar levels, and improved insulin sensitivity.
Ketones circulate in the blood and become the primary energy source for many cells in the body.
Similarly, a low-carbohydrate diet positively affects cholesterol levels, blood sugar, and body fat (2). The keto diet mimics the concept and effects of fasting by eliminating glucose from your diet, which naturally occurs in carbohydrate foods.
Ketosis is the metabolic state when most of the body’s energy is derived from ketones in the blood, not glucose, which is what keto stands for.
Your body is in ketosis when your blood ketone levels are elevated. With this, you can experience consistent and rapid weight loss.
By following a ketogenic diet, your body will burn excess fat faster, even if you consume a lot of fat and calories.

Different Types of Ketogenic Diets
Health experts have been saying that carbohydrates are not essential to build muscle. In fact, even if you’re into the ketogenic diet you can still build muscle due to the protein present in this diet. Although building muscle is slower on a keto diet, you can ensure that total body fat isn’t increasing.
The ketogenic diet has Three variations as listed below:
-
Standard ketogenic diet (SKD)
The standard ketogenic diet or SKD is the most popular among other types of keto diets. The general rule of SKD is to avoid starches and fruits and the required intake of carbohydrates is 30 g or less. It recommends consuming leafy green vegetables because of the low glycemic index that has less effect on insulin.
-
Targeted ketogenic diet (TKD)
This type of ketogenic diet requires consuming carbs during workout times. The TKD is designed for those people who are just newbies in an exercise program and those who are unable to follow the CKD plan.
-
Cyclical ketogenic diet (CKD)
People who are into advanced exercise programs like athletes and bodybuilders should follow the CKD plan. The high intensity and volume of training are needed to optimize the effect of the diet. The main goal of the cyclical ketogenic diet is to use up the muscle glycogen in loads of carbs.
Ketogenic Diet for Whom?
The ketogenic diet (KD) is a low-carbohydrate, high-fat diet with several health benefits, including weight loss, improved blood sugar control, and reduced risk of heart disease. However, only some are good candidates for the KD.
Some people who may benefit from the KD include:
- People with epilepsy. KD is an effective treatment for certain types of epilepsy, especially in children.
- People with type 2 diabetes. The KD can help to improve blood sugar control and reduce the need for medication in people with type 2 diabetes.
- People who are looking to lose weight. The KD can help to promote weight loss and improve metabolic health.
- People with certain types of cancer. Some research suggests that the KD may help slow cancer cell growth.
However, some people should not follow the KD, including:
- People with kidney disease. KD can strain the kidneys, so it is not recommended for people with kidney disease.
- People with liver disease. The KD can also strain the liver, so it is not recommended for people with liver disease.
- People who are pregnant or breastfeeding. There is not enough research on the safety of the KD for pregnant or breastfeeding women.
- People with any other underlying medical conditions. Talking to your doctor before starting the KD if you have any other underlying medical conditions is essential.
If you are considering trying the KD, you must talk to your doctor first. They can help you determine if the diet is proper for you and guide you on starting and following it safely.
Ketogenic diet weight loss – Does it work?
Just like any other low-carb diet plan, the ketogenic diet aims to eliminate glucose that is present in carbohydrates. Instead of producing glucose, when your body is in a ketosis state, it begins to burn the stored fat. Thus, following a ketogenic diet helps the body to burn the stored fat quickly.
Aside from shedding extra weight, burning fat also assists in controlling the release of insulin in people with diabetes and other health issues.
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 (3).
Another study found that participants on the ketogenic diet lost 3 times more weight than those on Diabetes UK’s recommended diet (4).
The main concept of the ketogenic diet is to eliminate carb intake in such a way that the carbohydrates present in the body are almost empty. It is beneficial to follow a keto diet to reverse the underlying cause of diabetes which is insulin resistance.

Keto Diet Before and After
How Much Weight Loss on Keto
Weight loss might differ based on your size and the amount of water you’re carrying. People reportedly lose anything from 1 pound (0.5 kg) to 10 pounds or more throughout the first week, according to anecdotal evidence (5 kg). You’ll probably lose more water weight after starting a keto diet if you’re bigger.
Health Benefits of Ketogenic Diet
Originally, the ketogenic diet is recommended for patients suffering from epilepsy. But, further studies revealed that this diet plan is also beneficial to other health conditions.
Other health benefits of the ketogenic diet include the following:
- Regulates blood sugar
The ketogenic diet is more effective in preventing and managing diabetes than other low-calorie diets. The foods included in the diet plan can reduce blood sugar levels. People suffering from Type II diabetes should consider following this diet plan.
- Weight loss
When you follow the keto diet, your body will use the fat stored as an energy source. With this, you can expect to lose weight. Likewise, the insulin level also decreases enabling your body to act as a fat-burning machine.
- Improves mental focus
Ketones serve as fuel for your brain. That’s why when you take a low-carb diet such as the ketogenic diet you can benefit from increased mental performance. As the blood sugar decreases, your focus and concentration improve.
- Boosts energy
Following the ketogenic diet, your body has a reliable energy source, thus you feel more energized. The fat present in the food you eat can make you feel full for a longer time.
- Normalize blood pressure and cholesterol level
A keto diet can normalize your blood pressure and cholesterol levels. It improves the triglycerides that eventually prevent arterial buildup. Low-carb diets show a dramatic decrease in LDL and an increase in HDL.
Moreover, the ketogenic diet is deemed to slow the growth of the tumor. It also reduces the symptoms of Alzheimer’s disease and deters the progression of such disease.
A study showed that this low-carb diet can improve the symptoms of Parkinson’s disease.
Common Side Effects of a Keto Diet
Just like any other diet plan, a keto diet also shows common side effects such as micronutrient deficiency and dehydration. If you’re following this diet plan, make sure to drink a sufficient amount of water and consume foods that are rich in micronutrients.
Other side effects of the ketogenic diet include the following:
- Cramps
When you’re starting a keto diet, you should anticipate experiencing leg cramps. It may happen at night or in the morning, but it’s just a minor issue. Such a condition is a sign that your body has an insufficient amount of minerals such as magnesium.
- Constipation
A Keto diet is deemed to be a diuretic that may cause dehydration. In the same manner, dehydration can cause constipation. That’s why if you’re taking a ketogenic diet you must drink more water than the recommended daily intake.
You should also consume vegetables that are rich in fiber to solve constipation or take a probiotic.
- Heart palpitations
Before you start this diet plan you should consult first your doctor. It’s because a keto diet can cause heart palpitations or make your heart beat faster and harder.
FAQ:
Can you have watermelon on a keto diet?
Watermelon can be consumed on a ketogenic diet in moderation. However, it is important to keep in mind that watermelon is a high-carbohydrate fruit and may not be suitable for those following a strict ketogenic diet.
One cup (154 grams) of diced watermelon contains approximately 11 grams of carbohydrates and 2 grams of fiber, which means it contains 9 grams of net carbohydrates. For reference, a typical ketogenic diet involves limiting your daily carbohydrate intake to 20-50 grams or less.
If you’re following a strict ketogenic diet and want to consume watermelon, it’s best to limit your intake to a small serving and adjust your other carbohydrate sources accordingly. Additionally, it’s important to track your daily carbohydrate intake and monitor your blood glucose levels to ensure you’re staying in a state of ketosis.
Are dates allowed on the keto diet?
Dates can be consumed in moderation on a ketogenic diet, although they are relatively high in carbohydrates. One date (24 grams) contains approximately 17 grams of carbohydrates and 2 grams of fiber, which means it contains 15 grams of net carbohydrates. For reference, a typical ketogenic diet involves limiting your daily carbohydrate intake to 20-50 grams or less.
If you’re following a strict ketogenic diet and want to consume dates, it’s best to limit your intake to a small serving and adjust your other carbohydrate sources accordingly. Additionally, it’s important to track your daily carbohydrate intake and monitor your blood glucose levels to ensure you’re staying in a state of ketosis.

Can you eat chicken on a keto diet?
Yes, chicken can be a great option for those following a ketogenic diet. Chicken is a lean protein source that is low in carbohydrates and high in healthy fats, making it a great option for those looking to maintain a state of ketosis.
Some options for incorporating chicken into a ketogenic diet include grilled or baked chicken breast, chicken thighs, or rotisserie chicken. It’s important to choose skin-on options and to avoid breaded or fried chicken, as these can be high in carbohydrates.
Additionally, incorporating healthy fats and low-carbohydrate vegetables, such as leafy greens or broccoli, can help to round out a ketogenic meal that includes chicken.
Keto diet without a gallbladder
If you do not have a gallbladder, it is still possible to follow a ketogenic diet, but there are some considerations to keep in mind.
The gallbladder stores and releases bile, which helps to break down fat in the digestive system. Without a gallbladder, the body may have difficulty digesting large amounts of fat, which can lead to digestive discomforts, such as abdominal pain, diarrhea, and nausea.
To help mitigate these symptoms, it may be necessary to start with a moderate amount of fat in the diet and gradually increase it over time, as the body adjusts. It may also be helpful to consume smaller, more frequent meals throughout the day, as opposed to large, high-fat meals.
Additionally, it is important to choose healthy fats, such as those found in olive oil, avocado, nuts, and seeds, as opposed to unhealthy fats, such as those found in processed foods or fried foods.
Final Verdict
It can be difficult to start a ketogenic diet, particularly during the transition period. But, knowing the benefits of this diet, many people were attracted to try it.
Once you start the diet plan, make sure to continue it as recommended. Follow the recommended foods and menu plan to achieve positive results. You need to be mindful of your food intake, especially your carb intake.
It’s also a good idea to talk to a healthcare professional or a registered dietitian before starting a ketogenic diet, as it can be a restrictive and challenging diet to follow and may not be appropriate for everyone.
