The Study
Breakfasts Higher in Protein Increase Postprandial Energy Expenditure, Increase Fat Oxidation, and Reduce Hunger in Overweight Children from 8 to 12 Years of Age.
This study showed that when kids ate a breakfast with more protein, their bodies burned more fat and they felt less hungry for a few hours — but it didn't make them eat less at lunch. So we know protein changes how their bodies work right after eating, but not if it helps them lose weight over time.

Where the score came from
This study tested if eating a breakfast with lots of protein (like eggs) instead of carbs (like cereal) makes kids burn more fat and feel less hungry.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Even though kids felt less hungry, they didn’t eat less at lunch, so protein didn’t help them eat fewer calories in this short test.
- 2Kids who ate the protein breakfast burned 16% more fat, felt 14% less hungry, and 32% fuller—but still ate the same amount of food at lunch.

When children aged 8 to 12 eat a breakfast with 18 grams of protein instead of one with 3 grams of protein, their bodies burn more fat and use more energy in the hours after eating, regardless of their weight.
For children aged 8 to 12, eating a breakfast high in protein instead of one high in carbohydrates leads to a measurable reduction in hunger and an increase in fullness within a few hours, regardless of their weight.
In children aged 8 to 12, eating a protein-rich breakfast makes them feel less hungry and more full than a carb-rich breakfast, but they still eat the same amount of food at lunch. This shows that feeling fuller doesn't always mean eating less.
Children who are overweight or obese burn more fat and use more energy after eating a high-protein breakfast than children of normal weight do, suggesting their bodies respond differently to the same meal.
When children aged 8 to 12 eat a breakfast high in protein instead of one high in carbohydrates, their bodies burn more carbohydrates for energy four hours after eating.
When the body processes a large amount of energy from food and physical activity, it burns more calories at rest, breaks down more fat, and reduces feelings of hunger, regardless of whether total calorie intake exceeds or falls short of expenditure.
