Ever Wondered What the Ketogenic Diet Is and How It Works? “Vad är ketodiet?”
The ketogenic diet is a high-fat, moderate-protein, and very low-carb eating plan designed to push the body into a metabolic state called ketosis. Normally, the body relies on glucose (sugar) from carbohydrates for energy. But when carbs are drastically reduced, the body begins to produce ketones in the liver, using stored fat as the primary fuel.
This shift not only changes how your body generates energy but also promotes fat burning and can influence overall metabolism.
What is a Keto Diet Food List?
A successful keto plan balances fats, proteins, and carbs in specific proportions:
70–80% Fats
- Avocados – rich in monounsaturated fats and fiber.
- Olive oil – high in oleic acid with heart-protective benefits.
- Nuts and seeds – almonds, walnuts, macadamia, flaxseeds, chia seeds.
- Fatty fish – salmon, mackerel, sardines, loaded with omega-3s.
- Eggs, chicken, fish, or plant-based options like tofu.
5–10% Carbohydrates
- Primarily from low-carb vegetables such as spinach, kale, zucchini, or cauliflower.
Typically, the keto diet cuts daily carbohydrate intake down to 50 grams (and in stricter versions, even as low as 20 grams). As glycogen stores (the body’s stored sugar) deplete, the liver begins to produce ketones from fat, turning them into the body’s main energy source.
Key Takeaway: The keto diet transforms your body’s energy system by shifting from carbs to fats as fuel. By carefully choosing the right foods—healthy fats, quality protein, and low-carb vegetables—you can maintain ketosis and experience the full effects of the ketogenic lifestyle.
Ketogenic Diet Benefits
The ketogenic diet has gained massive popularity in today’s health-conscious generation. From supporting weight loss to boosting energy levels and even offering therapeutic advantages, keto has been praised for its transformative potential. Let’s explore the main keto diet benefits that make this eating plan so appealing.
1. Weight Loss
One of the primary reasons people turn to keto is for weight loss. By drastically reducing carbohydrate intake, appetite naturally decreases. At the same time, the body begins to burn stored fat for fuel, promoting steady fat loss.
A 2018 review in Obesity Reviews confirmed that the ketogenic diet not only helps burn calories but also reprograms the body’s metabolism, making it more efficient in using fat as energy.
2. Stable Energy Levels
Unlike high-carb diets that cause blood sugar spikes and crashes, keto provides the body with a steady energy supply from ketones. Many followers report improved stamina and fewer afternoon slumps, making it easier to stay active and alert throughout the day.
3. Mental Clarity and Focus
Another benefit often highlighted is mental clarity. Some individuals notice reduced brain fog and sharper focus after adapting to keto. While much of this evidence is anecdotal, students and professionals alike report that a keto-friendly diet helps them concentrate better—thanks to ketones being a more efficient fuel for the brain.
4. Therapeutic Uses
Beyond weight loss and energy, keto also has medical applications:
- Epilepsy: Widely used to manage drug-resistant epilepsy, especially in children.
- Type 2 Diabetes: Research published in Diabetes Research and Clinical Practice (2019) shows improved glycemic control and reduced dependence on medication.
- PCOS (Polycystic Ovary Syndrome): Emerging evidence suggests keto may help regulate hormones and improve symptoms.
- Cancer Research: Preliminary studies indicate that keto may help starve glucose-dependent tumor cells, offering potential as a supportive therapy.
Key Point: The ketogenic diet is more than just a trend. With its unique ability to transform how the body and brain use energy, it provides not only effective weight management but also promising therapeutic potential in specific health conditions.

What Foods Should Be Avoided on a Ketogenic Diet Plan?
The keto diet is all about low-carb living. To stay in ketosis, you need to cut out foods that are high in carbohydrates, as even small amounts can push you out of this fat-burning state. Here’s a breakdown of the main foods to avoid on a ketogenic diet:
1. Fruits (The “Worst” Food for Keto)
While fruits are considered healthy in most diets, they are not keto-friendly due to their high sugar (carbohydrate) content. For example:
- Grapes and bananas are packed with carbs and should be completely avoided.
- Low-carb fruits like strawberries, raspberries, or blackberries can be consumed in small quantities without harming ketosis.
2. Grains and Starches
It’s an absolute no to starches on the keto diet. Foods like bread, rice, pasta, and potatoes are high in carbohydrates. Since grains are essentially complex sugars, even a single serving can exceed the daily carb limit of 50 grams. Cutting these out is essential for staying on track.
3. Processed Foods
How Exactly Is Carb Counting Done?
Carb counting is crucial for maintaining ketosis. Here’s how it works:
- Check the nutrition label or food guide for the carbohydrate content of a serving.
- Subtract fiber content from total carbs to calculate net carbs
- Example: If a food contains 20g carbs and 5g fiber, net carbs = 15g.
- Track your daily intake to ensure you stay below the recommended carb range (usually 20–50g of net carbs per day).
As a rule of thumb, each meal should roughly stay under 15 grams of net carbs to maintain ketosis.
Key Takeaway: Avoiding high-carb foods like fruits (bananas, grapes), grains, starches, and processed foods is non-negotiable for success on the keto diet. Smart carb counting ensures you stay in ketosis while still enjoying balanced, satisfying meals.
Keto Diet Side Affects You Should Know
The keto diet has gained massive popularity for weight loss, boosting energy, and improving overall health. But just like every pro has a con, this diet also comes with certain side effects that you should be aware of before starting.
Take the real story of a 19-year-old gymnast as an example. She switched to the ketogenic diet to lose weight and strengthen her body for intense training. However, within just a few days, she began to experience common keto side effects.
1. Keto Flu – The First Challenge
After 3 days on keto, she suffered from headaches, fatigue, and digestive discomfort. These symptoms are widely known as the keto flu. When the body transitions from burning carbs to burning fat, it takes time to adjust. During this phase, symptoms like dizziness, weakness, and brain fog are common.
To overcome this, her trainer recommended strategic hydration and replenishment of electrolytes like sodium, potassium, and magnesium. Since insulin levels drop on keto, electrolytes are flushed out quickly, making proper balance essential.
2. Nutrient Deficiency Risks
Another concern of the ketogenic diet is nutrient deficiency. Since keto restricts high-carb foods such as fruits, whole grains, and some vegetables, the body may lack essential vitamins—particularly vitamin C.
For this reason, she was advised to include low-carb, vitamin C-rich foods such as:
- Bell peppers
- Kale
- Broccoli
- Cauliflower
- Strawberries
Vitamin C works as a powerful antioxidant and helps strengthen immunity while supporting the effectiveness of the keto diet.
3. Heart Health Concerns
Some critics argue that a high-fat diet, especially if it includes too many saturated fats, may raise the risk of cardiovascular problems. Over time, this could potentially contribute to artery blockage. To lower this risk, experts recommend focusing more on healthy unsaturated fats from sources like olive oil, avocados, fatty fish, and nuts.
4. Practical Challenges of the Keto Diet
If practically taking into account, it may prove to be challenging for a typical person to strongly monitor their diet. Carbohydrates dominate most daily menus, which makes it difficult to manage family dinners or restaurant outings.
This means that the ketogenic diet requires:
- Careful monitoring of overall health
- Meeting body necessities with the right nutrition
- Responsible and consistent diet follow-up
Key Takeaway: The keto diet can provide amazing benefits for weight loss and energy, but it also comes with potential side effects such as keto flu, nutrient deficiencies, heart health concerns, and practical challenges in daily life. With professional guidance, balanced nutrition, and smart food choices, you can minimize risks and enjoy the true benefits of the ketogenic lifestyle.
Keto Diet and High LDL Cholesterol
One concern with keto is its effect on cholesterol levels. In some individuals—particularly those who are lean and fit, known as “Lean Mass Hyper-Responders”—the keto diet can significantly raise LDL cholesterol and Apolipoprotein B (apoB).
While keto may still support weight loss and blood sugar control, the rise in LDL could increase cardiovascular risk for some people. That’s why regular monitoring and medical guidance are important if you plan to follow keto long-term.
Takeaway: The keto diet can deliver impressive results, but it’s not without challenges. Skipping cheat days early, setting realistic weight loss goals, and watching cholesterol levels are all essential for a safe and effective keto journey.
Why Experts Criticize the Keto Diet
Interestingly, the ketogenic diet was ranked among the worst diets of 2021 by a panel of health professionals. Unlike balanced eating approaches such as the Mediterranean diet, keto is highly restrictive, cutting out most carbohydrate sources. This makes it difficult for the average person to maintain, especially when dining out or sharing meals with family.
While keto can lead to fast results in weight loss, health experts warn that the plan is not sustainable for many people. In addition, its restrictive nature has been linked to:
- Nutrient deficiencies from cutting out key food groups.
- Cardiovascular risks, including higher LDL cholesterol in some individuals.
- Mood disturbances, as low-carb diets can affect brain chemistry and energy levels.
In short, keto may work as a short-term fix—but when it comes to long-term health, it falls short compared to more balanced diets.

Even with its critics, there’s no denying that many people—including celebrities—have used keto to shed unwanted pounds. For example:
- Melissa McCarthy reportedly slimmed down with the help of a keto-style eating plan.
- Al Roker, the famous TV host, shared his weight-loss journey with keto.
- Savannah Guthrie, co-anchor of the Today Show, also turned to keto to lose weight.
Common Questions About the Keto Diet
Is Cheat Day Allowed in Keto Diet?
How Long Does It Take to Notice a Change in Appearance on Keto?
Many people notice changes within the first week due to rapid water loss, which can make you look slimmer. Some individuals lose several pounds in the first 1–2 weeks. However, this early drop is mostly water weight, not fat.
True fat loss becomes noticeable after a few weeks to a few months of strict keto dieting. Consistency is key if you want visible, lasting results.

Is the Keto Diet Really Worth It?
The Bottom Line
Is the keto diet the “stupidest diet to ever exist”? For some experts, yes—because of its risks and lack of universal health benefits. For others, especially those with specific medical conditions like type 2 diabetes or obesity, keto may offer short-term advantages.
Ultimately, the key is personalization. A diet plan should not only help you lose weight but also support long-term health. Before starting keto—or any restrictive diet—it’s best to consult a doctor or nutritionist to determine whether it truly fits your body’s needs.
