Article Summary

In the article Could Your Healthy Diet Make Me Fat written by David S. Ludwig published on November 28, 2015 is about how diets may be genetically-influenced yet eating less processed carbohydrates is still the most effective advice. Ludwig argues that all diets must be personalized to be the "right" diet for a person. He mentions an Israeli study found insulin-30 levels to best predict how a person's diet may influence weight gain. This measured a person's insulin level 30 minutes after eating. Ludwig cites this study as a major source of information on how preconceptions of "healthy food" could be fattening or bad for some people therefore person-specific diets are for the future, but currently to emphasize the quality of carbohydrates to prevent obesity.

Article Critique

Ludwig holds an MD/PhD from Stanford University School of Medicine, further education focused in pediatric endocrinology, published over 150 articles, is a current writer on JAMA, and founded the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital conducting research on how hormones may influence obesity. His article, published in the opinion section of the New York Times, is written emphatically on several points which Ludwig further supports with evidence from valid scientific studies. Ludwig was able to write eloquently to his audience which is not a science-based community. As a result, the article was readable yet contained solid background and supportive facts that easily convinced the reader of his main points about how personalized diets could be the future. Although the article did mention that eating less refined carbohydrates should remain the major emphasis in advice for losing weight, the article could have been bettered by showing such evidence. Ludwig abruptly ends his article with summation that personalized nutrition is not yet ready for clinical practice. He does mention the Nurses’ Health Study, which is highly credited in the health science community but fails to mention which specific study would be able to further support his point for his readers. Ludwig was able to provide ethos to the argument about personalized nutrition by citing the Israeli study, another clinical study, his own 2007 research, and an article in Obesity, as well as paralleling his point to the personalized medicine trend. In conclusion, Ludwig’s point on future personalized nutrition was well made, yet his point about the emphasis of eating less refined carbohydrates was poorly supported in contrast.
