The Claim
Consuming an ultra-processed breakfast compared to a less processed breakfast is associated with significantly higher postprandial insulin levels and greater subjective hunger over a 120-minute period in adults, regardless of body mass index.
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.
Adults who eat ultra-processed breakfasts have higher insulin levels and feel hungrier for two hours after eating compared to those who eat less processed breakfasts, regardless of their body weight.
See the scientific wording
Consuming an ultra-processed breakfast compared to a less processed breakfast is associated with significantly higher postprandial insulin levels and greater subjective hunger over a 120-minute period in adults, regardless of body mass index, suggesting that the degree of food processing may independently influence short-term appetite and metabolic responses.
Ultra-processed breakfasts break down quickly in the gut, causing blood sugar to spike fast. The pancreas responds by releasing a large amount of insulin, which pulls sugar out of the blood too quickly. This drops blood sugar below normal levels, which directly signals the brain to increase hunger, even though the person just ate.
What the research says
1 studyPeople who ate a breakfast made of highly processed foods felt hungrier and had higher insulin levels afterward than when they ate a less processed breakfast—even if they were thin or overweight. This suggests the type of food processing itself affects hunger and blood sugar, not just body weight.
