Consuming ≥1 serving per day of breakfast cereal (both whole and refined grain types) is associated with a significantly lower risk of becoming overweight (BMI ≥25 kg/m²) and reduced long-term weight gain in middle-aged and elderly men compared to rare or non-consumption.
For men looking to manage weight, eating at least one serving of breakfast cereal daily is associated with a lower risk of becoming overweight over the long term. This benefit appears to apply to both whole grain and refined grain cereals, suggesting that the act of eating a structured breakfast (likely with portion control and satiety benefits) is more important than the specific grain type. It is not a magic bullet, but a consistent habit linked to healthier weight outcomes in this population.
Compared with men who rarely or never consumed breakfast cereals, those who consumed ≥1 serving/d of breakfast cereals were 22% and 12% less likely to become overweight during follow-up periods of 8 and 13 years (relative risk, 0.78 and 0.88; 95% confidence interval, 0.67 to 0.91 and 0.76 to 1.00, respectively).
Why this rating
Large prospective cohort (n=17,881), long follow-up (8-13 years), adjusted for major confounders, but observational design prevents causal inference and relies on self-reported dietary data.
