The ketogenic diet – or keto diet for short – has been one of the most popular diets for years. It is primarily associated with weight management, focus, and more conscious food choices. But what is truly behind the keto principle? In this article, we explain the basics, highlight potential benefits, and point out common mistakes to avoid.
What is the Keto Diet?
The keto diet is a low-carb, high-fat diet. The goal is to put the body into a state called ketosis. In ketosis, the body primarily uses fat – specifically ketone bodies – as an energy source instead of glucose from carbohydrates.
Typical macronutrient distribution for keto:
-
70–75% Fat
-
20–25% Protein
-
5–10% Carbohydrates
In concrete terms, this means: sugar, bread, pasta, and highly processed carbohydrates are largely reduced, while high-quality fat sources and protein-rich foods are the focus.
What foods are allowed on Keto?
A well-planned keto diet relies on natural, minimally processed foods:
Suitable foods include:
-
Avocados, olives, nuts & seeds
-
High-quality oils (e.g., olive oil, MCT oil)
-
Meat, fish, eggs
-
Cheese & high-fat dairy products
-
Low-carb vegetables (e.g., zucchini, broccoli, spinach)
To avoid are:
👉 Erythrit - the ideal sugar substitute
Potential benefits of the keto diet
The keto diet is practiced for various reasons. Commonly mentioned aspects are:
-
More conscious approach to food through clear selection criteria
-
Reduced carbohydrate intake, which many find suitable for everyday life
-
Satiating nutritional profile due to fat and protein content
Important: Effects can vary individually and strongly depend on lifestyle, food quality, and personal situation.
Common mistakes in the keto diet
Beginners often make similar mistakes that can complicate the start:
1. Too few electrolytes
Due to reduced carbohydrate intake, the body excretes more water and minerals. Insufficient supply of sodium, potassium, and magnesium can have negative effects.

2. Too much protein
Keto is not synonymous with high-protein. Excessive protein intake can lead to the body producing more glucose, making ketosis more difficult.
3. Focus on the wrong fats
Not every fat is automatically recommended. Trans fats and highly processed vegetable oils should be avoided.
👉 Medium-chain fatty acids, such as those in GreatVita's MCT oil, have proven effective and can be easily integrated into coffee or smoothies.
4. Lack of planning
Without preparation, keto can quickly become unbalanced. Structured meal planning helps to avoid nutrient gaps.
Keto and supplements – a sensible combination
A ketogenic diet places special demands on nutrient supply. In addition to food choices, many rely on selected micronutrients:
-
Magnesium
-
Omega-3 fatty acids
-
Vitamin D

Conclusion: Is keto right for you?
The keto diet is not a short-term trend, but a clearly structured diet that requires discipline and knowledge. Those who familiarize themselves with the basics, avoid common mistakes, and pay attention to high-quality foods can integrate keto into their daily lives consciously and sustainably.
As with any diet, listen to your body and inform yourself thoroughly – quality and balance always come first.
