Another difference between older and newer studies is that the type of patients treated with the ketogenic diet has changed over time. When first developed and used, the ketogenic diet was not a treatment of last resort; in contrast, the children in modern studies have already tried and failed a number of anticonvulsant drugs, so may be assumed to have more difficult-to-treat epilepsy. Early and modern studies also differ because the treatment protocol has changed. In older protocols, the diet was initiated with a prolonged fast, designed to lose 5–10% body weight, and heavily restricted the calorie intake. Concerns over child health and growth led to a relaxation of the diet's restrictions. Fluid restriction was once a feature of the diet, but this led to increased risk of constipation and kidney stones, and is no longer considered beneficial.
Puede ser curada de Parkinson si se detecta temprano
en principio la dieta cetogénica no afecta el ritmo cardiaco. Lo que sí es cierto que durante la cetosis existen más cetoácidos en la sangre. Los riñones eliminan cetoácidos del cuerpo de manera natural. Si éstos se acumulan en la sangre más allá de la capacidad de los riñones para eliminar el ácido, se puede presentar fatiga, latido del corazón irregular o mareos, y cuando tengas estos síntomas no es recomendable entrenar.
