Step-by-step explanation:
Why extreme calorie-restricted diets are considered unhealthy
Extreme calorie-restricted diets are considered unhealthy due to several reasons. Firstly, when too much fat is lost too quickly, it can lead to inadequate organ function, as the body needs a certain amount of fat for optimal health. Additionally, fad diets often discourage exercise, which is important for overall health and well-being. Moreover, these diets may rely on supplements or medications for weight loss, which can have potential side effects. Lastly, extreme calorie restriction can result in inadequate consumption of essential nutrients like vitamins, which are crucial for proper bodily functioning.
