Macro partitioning
Consuming a high-protein breakfast (34g) versus a low-protein breakfast (6g) for 12 weeks increases subjective satiety but does not result in significant changes in body composition (fat mass, lean mass, weight) or cardiometabolic health markers in young women with overweight.
Eating a high-protein breakfast (around 34g) will likely make you feel fuller throughout the morning compared to a low-protein breakfast. However, if your goal is weight loss or improved blood markers, simply switching to a high-protein breakfast without other changes (like reducing overall calories or increasing exercise) is unlikely to produce results in young overweight women. The increased satiety did not lead to a significant reduction in daily energy intake or body fat in this study.
Conclusively, a high v. low content of protein in breakfast increased satiety but did not affect body composition or cardiometabolic markers in young women with overweight.
Why this rating
Randomized controlled trial with adequate sample size (n=56) and clear intervention, though limited to a specific demographic.
