Calculadora de Dieta Cetogênica

The Ketogenic Diet Calculator is designed to help you plan your meals following the classic ratio of 70% fat, 25% protein, and 5% carbohydrates. This split is the foundation of the ketogenic diet, which aims to induce ketosis, a metabolic state where the body uses fat as its primary energy source. The calculator is useful for both beginners and those already on the diet who need to adjust portions according to their daily caloric needs.

How it works: you input your total daily energy expenditure (calories) and the tool calculates how many grams of each macronutrient you should consume. It uses energy density values: 9 kcal/g for fat, 4 kcal/g for protein, and 4 kcal/g for carbohydrates. The result shows daily targets in grams, making it easier to plan meals and choose appropriate foods.

When to use? This calculator is ideal for people who want to start or optimize a ketogenic diet, whether for weight loss, blood sugar control, improved energy, or other reported benefits. It is also useful for healthcare professionals guiding patients on this eating plan. Remember that ketosis requires severe carbohydrate restriction, usually below 50g per day, and any variation in the ratio can compromise results.

Important precautions: the ketogenic diet is not recommended for everyone. People with kidney, liver, pancreatic issues or eating disorders should consult a doctor before starting. Also, it is common to experience initial symptoms like the 'keto flu' (fatigue, headache, irritability) that usually pass in a few days. Stay hydrated and consider electrolyte supplementation, as water and mineral loss is greater at the beginning.
