What is a ketogenic diet and how does it work?

A ketogenic diet limits carbohydrates and focuses on fats and proteins. It changes the type of energy your body uses, resulting in ketosis. During ketosis, your body burns fat instead of sugar. This process can bring health benefits such as weight loss and increased energy.

The science behind ketosis

In ketosis, the body produces small energy molecules called ketones. These ketones come from fat processed by the liver. Essentially, your body begins to use fat as its primary source of energy instead of carbohydrates—helping promote weight loss.

Proven benefits of a ketogenic diet

Studies show that a ketogenic diet can support weight loss and overall health improvement. People report less hunger and more energy. Other benefits include better blood sugar control and reduced heart disease risk.

Debunking common myths about the ketogenic diet

Many believe a high-fat diet is bad. But in a ketogenic diet, healthy fats are key—they’re essential to staying healthy while in ketosis. It’s important to choose quality fat sources like avocados, nuts, and fish.

Common transformations reported by keto followers

Inspiring weight-loss stories

Many people report losing a lot of weight with this diet. Selton Chagas, for instance, lost over 15 kilos. He not only slimmed down but also gained muscle and improved his overall quality of life. Real results like his show that dedication to the ketogenic diet can yield outstanding outcomes.

Improvements in health and overall well-being

It’s not just about weight. Health as a whole can improve significantly. Lya, who had diabetes and high blood pressure, saw her well-being soar after adopting a strict low-carb diet. Francisco, 53, proved that switching to low-carb eating and exercising more could promote both weight loss and better health.

Cíntia and Andreia also have impressive stories. Cíntia thought she was healthy but decided to change her diet—losing 12 kilos in two months. Andreia lost an incredible 62.5 kilos with a mainly paleo, low-carb approach.

These examples show how the ketogenic diet can bring astonishing transformations—both physically and mentally—when followed with discipline.

How to plan a weekly ketogenic menu

Planning a keto weekly menu is simple. Choose low-carb foods from groups such as meats, eggs, cheeses, and vegetables. For breakfast, try scrambled eggs with bacon. For lunch, go for a bunless burger with green salad. For dinner, grilled fish with asparagus is an excellent option.

Snacks are key for maintaining satiety—almonds, cheese, and avocado are practical and healthy options.

Variety is crucial. Alternate protein sources and vegetables throughout the week to avoid monotony while meeting nutritional needs.

Consistency and preparation are your best allies on this journey.

Allowed and prohibited foods on a ketogenic diet

The keto diet encourages high intake of certain foods while avoiding others to help your body burn fat instead of carbs.

Allowed: meats, fish, eggs, cheese, nuts, and above-ground vegetables.
Avoid: high-carb foods like bread, pasta, rice, and sweets. Fruits are limited—only low-carb ones like strawberries.

Success stories like Selton Chagas (lost 15 kg) and Claudio Hollanda (lost 60 kg after a near-death experience) show how powerful this diet can be.

How to start a ketogenic diet safely and effectively

First, understand that the ketogenic diet is high in fats and low in carbs—shifting your body’s fuel from glucose to fat.

Tips for beginners:

Eliminate sugars and grains.
Choose healthy fats (avocado, nuts, olive oil).
Drink plenty of water to stay hydrated.

Avoid common mistakes:

Not eating enough fats (can stop ketosis).
Ignoring electrolytes (can cause “keto flu”).
Add Himalayan or pink salt to meals and consider magnesium/potassium supplements.

Long-term effects of the ketogenic diet

Research shows lasting benefits like sustained weight loss, better blood sugar control, and improved energy levels. However, nutrient deficiencies can occur if the diet lacks variety.

Professional guidance ensures safe, long-term success.

Keto diet and exercise: how to combine them

In ketosis, fat becomes your main energy source. Adjust your workout accordingly:

High-intensity training may require modifications.
Endurance activities (walking, swimming, cycling) often improve in ketosis.

Stay hydrated and consume potassium- and magnesium-rich foods to prevent cramps. Start slow and increase intensity as your body adapts.

Before and after: typical results

Before-and-after photos show clear transformations—weight loss, muscle gain, and renewed confidence.

People like Selton (−15 kg), Claudio (−60 kg), and Cíntia (−12 kg) highlight the dramatic, real-world effects of keto.

Is the ketogenic diet suitable for everyone?

Not necessarily. It’s not advised for people with liver, pancreas, or heart issues, or for pregnant/breastfeeding women.

Every person reacts differently, so professional supervision is key.

How long should you follow a ketogenic diet?

Experts recommend 2–4 months, depending on your goals and results.

Real cases like Selton, Claudio, Gizelly, Lya, Francisco, Cíntia, and Andreia show major transformations in both body and health.

How the ketogenic diet affects mood and energy

Many report better moods and sustained energy after the adjustment period. Fat-based energy prevents sugar highs and crashes, stabilizing mood and focus.

Keto’s influence on chronic conditions

The ketogenic diet can help manage diabetes, hypertension, and other chronic diseases by improving insulin sensitivity and reducing sodium retention.

However, medical supervision is essential.

Healthy alternatives for those who can’t adapt to keto

The paleo and Mediterranean diets are excellent alternatives—less restrictive, but still promote weight loss and health improvements.
