The Claim
A single breakfast meal containing 20 grams of protein from high-protein instant ramen noodles reduces subsequent lunchtime energy intake by an average of 94 kcal compared to an isocaloric meal with 6 grams of protein in healthy adults aged 25–45 with BMI 20–30, and this reduction occurs without changes in subjective hunger or satiety ratings.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating a breakfast with 20 grams of protein from high-protein instant ramen reduces the amount of food eaten at lunch by 94 calories on average, compared to a breakfast with 6 grams of protein, even when hunger and fullness feelings are unchanged.
See the scientific wording
A single breakfast meal containing 20 grams of protein from high-protein instant ramen noodles reduces subsequent lunchtime energy intake by an average of 94 kcal compared to an isocaloric meal with 6 grams of protein in healthy adults aged 25–45 with BMI 20–30, suggesting that protein preload can acutely suppress food consumption even without changes in subjective hunger or satiety ratings.
Eating more protein triggers the gut to release hormones that signal the brain through nerves connected to the stomach, causing the person to eat less at the next meal without feeling any different in hunger or fullness.
What the research says
1 studyPeople who ate a breakfast with more protein from special ramen ate about 94 fewer calories at lunch than those who ate regular ramen, even though they didn’t feel any fuller or hungrier — so the extra protein helped them eat less without them realizing it.
