His first argument to support his claim is that chocolate makes you fat. He uses his prior knowledge to support this fact by claiming that candy bars can contain more than 200 calories, that they contain fat and sugar, and that skinny people are vegetarians or athletes. Diego's second point is that newspapers are not always trustworthy. He uses examples from his experience, news circulating about the health benefits of red wine and the unnecessary promotion of gluten-free foods. His final point is that the study from the journal article was invalid. He uses evidence that testing only healthy people leads to skewed results and that the study should have included unhealthy chocolate eaters. Diego's first statement that chocolate makes you fat is almost accurate. His first two points of support are valid, but his absolute assertion that skinny people are vegetarians or athletes is incorrect, which weakens his argument. His second statement that newspapers are untrustworthy is a good point, but using Facebook is not necessarily a good source. His third point regarding the validity of the study is a very good argument. Since the study only included healthy people, the results regarding their BMI were not very reliable. Claiming that the study should have included unhealthy chocolate eaters strengthens the argument
