Is Keto a Diet

author avatar Dr. Eric Berg 01/17/2025

Let's face it: the word "diet" often evokes images of deprivation and restrictions. This can make it confusing when we hear about the ketogenic diet, often shortened to "keto."

So, is keto a traditional diet? This exploration might just change your perspective. Many people associate "diet" with a temporary change in eating habits.

It might conjure up feelings of eating bland foods until a goal weight is reached, only to revert back once the pounds are shed. Keto sometimes gets lumped into this same restrictive-sounding category.

What Exactly is Keto, Anyway?


The ketogenic diet is a metabolic approach to eating. It causes your body to transition from using glucose to using fat as its primary fuel source.

This metabolic shift, known as ketosis, produces ketones, an alternative energy source, and burns stored body fat.

How Ketosis Works

This metabolic shift, known as ketosis, has significant effects on the body. It hinges on a specific macronutrient ratio of approximately 70-80% fat, 20-25% protein, and 5-10% carbohydrates.

This low-carb, high-fat balance encourages the body to enter ketosis. In ketosis, the liver produces ketone bodies to supply energy. This process is efficient for burning stored body fat.

A true keto diet also typically includes grams of fat and specific grams of protein, which a dietician can advise on.

The History of Keto

Keto originated in the 1920s as a therapy for epilepsy, particularly in children. It effectively managed seizures before the development of anti-epileptic medications.

It was a high-fat and limited carbohydrate food group diet that many doctors used with success. Today, keto continues to help manage epilepsy and is increasingly popular for supporting metabolic health and balancing blood sugar and cholesterol levels.

Its potential benefits in other health areas are under investigation. Many people use keto as part of a weight and wellness plan to lose weight.

Research on keto's benefits for metabolic conditions is promising, showing exciting possibilities under clinical oversight.

Is Keto a Diet for Weight Loss?


Many people find weight loss success with keto. The body's efficiency in burning stored fat is a primary reason for rapid weight loss, often seen in the initial weeks.

Keto is indeed a fat diet, where a high amount of daily calories come from dietary fats. However, this should be healthy unsaturated fats.

It's not just about a diet weight, it has other health benefits, too. Beyond weight loss, many adopt keto to address rising rates of diabetes and prediabetes.

It may improve heart health by influencing blood pressure and cholesterol.

Balancing Blood Sugar

Reduced carbohydrate intake in a ketogenic diet keeps blood sugar from spiking and dipping. This can also help to balance energy levels, potentially improve mood swings, and stabilize metabolic syndrome markers.

Boosting Brain Function

Many individuals on keto report enhanced cognitive function. The steady energy from fats may improve mental clarity.

Olive oil, cocoa butter, and other healthy unsaturated fats can support this process. Though helpful, keto has pitfalls.

Is Keto a Diet That's Right for You?


While popular, keto isn't for everyone. People with conditions like kidney problems or fat metabolism issues should avoid keto.

Others, such as pregnant or nursing women, should only attempt keto under strict medical supervision from an experienced professional.

Athletes might find benefits or detriments when switching to keto. They should consult with a professional before adopting a high-fat diet like keto, as their body burns fat in a specific way.

Blood tests can also help athletes customize nutrition plans. Is keto a diet free of downsides? No. Let's explore potential pitfalls.

Potential Pitfalls of Keto

Starting keto can bring on the "low-carb flu." This flu-like adaptation process, lasting a few days to a few weeks, may involve symptoms like fatigue and headaches.

This typically takes between a few days and a few weeks. It is thought to be related to the body adapting to a new fuel source.

It highlights the importance of electrolyte intake, especially magnesium, potassium, and sodium. Healthy food groups, like leafy greens, bell peppers, summer squashes, swiss chard, and Brussels sprouts, contain many essential electrolytes.

Getting enough is important, as not having enough may cause symptoms of nausea, headaches, and constipation.

How Long Should You Stay on Keto?


The duration depends on individual goals. For blood glucose regulation, a longer duration on a balanced keto meal plan, combined with exercise, may provide lasting maintenance.

Blood tests with ongoing nutritional evaluation can help track progress. For fat and weight loss, cyclical keto might be appropriate.

This can involve cycling between high and low-carb intake based on how your body burns carbohydrates. You may see different benefits, so check with a doctor before doing this on your own.

This approach can enhance compliance and is best done with the guidance of a registered dietitian or healthcare provider.

Tailoring Keto for Different Body Types


While the ketogenic diet is often seen as a one-size-fits-all approach, individual body types can significantly influence how it works.

For example, people with an endomorphic body type, characterized by a higher tendency to store fat, may need specific adjustments to optimize their results.

Combining keto principles with an endomorph diet focuses on moderating fat intake while prioritizing lean proteins and low-carb vegetables to enhance fat-burning and improve metabolic efficiency.

This personalized approach ensures the diet aligns with the unique needs of endomorphs, who may benefit from slightly lower calorie intake and increased physical activity.

Understanding how keto works within the framework of different body types can make the diet more effective and sustainable for long-term health and weight management.

Conclusion

 

So, is keto a diet? It depends on the perspective. Whether used short-term for athletic performance or long-term for metabolic health management, keto requires careful consideration and professional guidance.

The duration and specific approach should align with individual health goals and be medically supervised for safety and efficacy.

For those dealing with issues such as diabetes, heart disease, blood pressure, or LDL cholesterol, there are specific considerations for this restrictive diet and how your body burns food for fuel, which may even impact your sleep hygiene, etc.

Keto is a controversial approach because a normal diet would often involve far less saturated fats and an alternative ratio between your carbohydrate diet and fat intake, which in turn affects the way the brain works.
