The study only compared the frequency of eating cereal for breakfast and body weight, without controlling for other factors that could affect weight, such as overall diet and physical activity levels. This means that there could be other confounding variables that may have influenced the results, making it difficult to determine a causal relationship between eating cereal and reducing obesity. The potential funding bias from the regional dairy council should also be noted. The Hawthorne effect (improved behavior due to being observed) and ecological validity (generalizability to real-life settings) may not necessarily be major issues with this study.
