The Claim

In children aged 8 to 12 years, a protein-based breakfast containing 18 grams of protein increases postprandial fat oxidation by 16% and energy expenditure compared to a carbohydrate-based breakfast with 3 grams of protein, independent of weight status, indicating that macronutrient composition directly influences metabolic substrate utilization during the hours following a meal.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

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.

  1. 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.

    Kids who ate a breakfast with lots of protein (like eggs or yogurt) burned more fat and used more energy after eating than kids who ate a breakfast full of carbs (like cereal or toast), no matter if they were thin or heavier. This shows what you eat for breakfast can change how your body uses energy.
