The topics of weight management, immunity and infections are the topics that struck me the most. When it comes to weight control, I've learned that diets don't work because they don't make permanent changes. Most diet plans are rich in proteins and carbohydrates. Furthermore, diet plans are based on marketing. In this topic I also learned that the BMI chart does not measure body fat and is inaccurate for short people. This topic affected me because as I said at the beginning, I suffered from eating disorders in the past and my weight was not constant. One week I was super fat and the other week I was super skinny, so I didn't know how to manage my weight. The information that the professor gave us on this topic helped me a lot because now I know that dieting doesn't work and that there is a right way to lose or gain weight and manage our weight well.
