Final answer:
A healthy diet is expected to result in weight loss and improved health, reducing the risk of many chronic diseases and benefiting mental health.
Step-by-step explanation:
Effects of Diet on Health
Doctors typically believe that a healthy diet will lead to weight loss and improved health. A diet rich in nutrients and low in unhealthy fats and sugars can significantly reduce the risk of obesity, cardiovascular disease, type 2 diabetes, osteoporosis, and cancer. Additionally, such a diet is linked to better mental health, potentially reducing the risk of dementia and positively affecting memory.
Conversely, fad diets that promise rapid weight loss without consideration for nutrient balance or exercise can increase the risk of chronic diseases and lead to a cycle of weight loss and gain without long-term benefits. Therefore, doctors would be likely to assert that a balanced diet has numerous positive effects on an individual's health.
