The Keto Diet differs from many other eating patterns because it changes the proportion of the three main macronutrients: carbohydrates, proteins, and fats.
Each macronutrient plays an important role in supporting normal body functions.
Carbohydrates provide energy and are found in foods such as grains, fruits, vegetables, and legumes. A ketogenic diet substantially limits carbohydrate intake.
Protein supports muscle maintenance, tissue repair, and many essential biological processes. Keto generally emphasizes moderate protein intake.
Fats provide energy, support cell function, and help the body absorb fat-soluble vitamins. They become the primary dietary energy source on keto.
Choosing the right types of fats is particularly important. Unsaturated fats from olive oil, nuts, seeds, avocados, and fish are generally preferable to relying heavily on saturated fats from butter and processed meats.
Because restricting carbohydrates can also reduce fiber and certain micronutrients, careful food selection is essential.
Consult a healthcare provider or registered dietitian before making significant changes to your macronutrient intake to ensure your eating plan meets your individual nutritional needs.
