For whom might a ketogenic diet be safe, according to current understanding?

A ketogenic diet may be considered safe for individuals who exercise moderately and eat whole foods. This diet, which is low in carbohydrates and high in fats, encourages the body to enter a state of ketosis, where it burns fat for fuel instead of carbohydrates.

Individuals who are active and consuming whole foods typically have a better balance of nutrients available to support their overall health and performance. Being moderately active means that their bodies can adapt to utilizing fats as a primary energy source more effectively. Additionally, whole food consumption ensures they are likely receiving essential vitamins and minerals that can help mitigate potential deficiencies that may arise from strict dietary restrictions often associated with ketogenic diets.

In contrast, individuals consuming solely processed foods would likely lack the essential nutrients required for a healthy diet, making a ketogenic diet potentially harmful. Those who do not exercise might struggle with the metabolic adjustments required for a ketogenic diet, as a sedentary lifestyle may not benefit from the fat adaptation process. Highly active athletes may also face challenges as their energy needs are more significant and primarily sourced from carbohydrates; thus, a strict ketogenic diet might not provide the necessary fuel for their performance and recovery needs.
