An American doctor revealed that striving for one diet that is suitable for all people is an unrealistic idea, stressing that the different nature of bodies and…Metabolism It makes it impossible to apply a uniform diet that achieves the same results for everyone.
A doctor explains why there is no diet that suits everyone
According to a report published by Fox News, Dr. Mark Hyman said, during a recent episode of his podcast, that the best diet is the one that matches the body’s individual needs, noting that every person responds to food in a different way.
Hyman explained that the essence of healthy nutrition is not about following the name of a specific diet, but rather about distinguishing between real food and what he described as “food-like substances,” referring to ultra-processed products that lack real nutritional value.
He added: Food is not just a source of energy, but rather a medicine. Everything that enters your body either helps you or hurts you.
The doctor emphasized that minimally processed foods, which are recognizable in their natural form, are radically different from processed foods that are produced for convenience and long shelf life.
Blood sugar is key to nutritional response
Hyman pointed out that regulating blood sugar levels is a crucial factor in how the body reacts to food, warning against diets rich in sugars and refined starches, because they have a negative impact on metabolism and general health, including mental health.
In this context, he talked about the keto diet, explaining that it depends on greatly reducing carbohydrates to stimulate the body to burn fat instead of sugar, a state known as ketosis, pointing out that ketones are an effective source of energy, especially for the brain.
However, he stressed at the same time that keto is not inherently healthy if it is followed incorrectly, stressing that there is a difference between keto that is based on whole foods and healthy fats, and another that is based on manufactured products.
Hyman explained that other diets such as paleo or vegetarianism may also be suitable, provided that you adhere to whole foods and avoid relying on manufactured products, stressing that the vegetarian diet is not healthy if it is limited to potato chips and soft drinks.
He also pointed out that the effectiveness of the Mediterranean diet depends on its correct application, distinguishing between the traditional version rich in vegetables, olive oil and fish, and the modern versions that focus on pasta and refined flour.
