Low-carb diets, like the ketogenic diet, have gained popularity for rapid weight loss but have unintended consequences. These diets have disrupted the food industry and harmed local economies. They can also harm the digestive system, potentially leading to colon cancer and malnutrition. While they promote avoiding processed foods, a more balanced approach to weight management, involving healthy carbs, calorie control, and exercise, is recommended for long-term health and well-being.
