We analyzed one assertion on this question, and it suggests that among healthy adults aged 25–45 with a normal weight, eating a 20g protein breakfast from instant ramen may lead to about 10% less food consumed at lunch compared to a 6g protein version, without changes in hunger, fullness, or cravings for fatty or salty foods [1]. What we’ve found so far is limited to this single assertion, which does not describe how the study was conducted, who participated beyond age and weight range, or whether results were measured over multiple days. There is no mention of how protein was delivered beyond “instant ramen,” nor whether other nutrients or meal timing were controlled. We also don’t know if this effect was consistent across individuals or if it lasted beyond one meal. The assertion claims no difference in subjective feelings like hunger or cravings, which suggests the reduction in lunch intake might not be driven by how full people felt, but possibly by other factors like digestion speed, hormonal response, or food composition. However, without details on methodology or replication, we can’t say whether this pattern holds under different conditions. We have no studies that contradict this finding, but we also have no additional data to confirm how reliable or repeatable it is. The evidence we’ve reviewed so far leans toward a possible effect of higher protein from instant ramen on reducing lunch intake, but it’s based on a single, minimally described assertion. In everyday terms: if you’re eating instant ramen for breakfast and want to eat a bit less at lunch, choosing a version with more protein might help — but we don’t yet know if this works for everyone, or if it’s just a one-time effect.
