@jack: Dr. Jack Kruse is a neurosurgeon and health educator who has gained a following for his ideas about the importance of light exposure and the negative effects of modern technology on our health. He believes that our modern lifestyles, which involve spending most of our time indoors and being exposed to artificial light and electromagnetic radiation, are contributing to a host of health problems, including obesity, diabetes, and cancer.
Kruse advocates for spending more time outdoors, especially in natural sunlight, and avoiding exposure to artificial light and electromagnetic radiation as much as possible. He also recommends following a ketogenic diet, which is high in healthy fats and low in carbohydrates, as a way to improve overall health and reduce inflammation.
While some people have reported success with Kruse's methods, others are skeptical of his claims and methods. Some experts have criticized his ideas as being unscientific and lacking in evidence. As with any health advice, it's important to do your own research and consult with a qualified healthcare professional before making any major changes to your lifestyle or diet.
