An unhealthy diet typically includes excessive amounts of processed foods, sugary drinks, and high-fat snacks. These foods often contain high levels of added sugars, salt, and unhealthy fats, which can lead to weight gain and various health issues. Consuming too many calories without adequate nutrients can result in deficiencies and negatively impact overall well-being. Additionally, an unhealthy diet may lack essential food groups, such as fruits, vegetables, and whole grains. This imbalance can increase the risk of chronic diseases like diabetes, heart disease, and obesity. Making healthier food choices is crucial for maintaining good health and preventing these conditions.
