The Claim
In healthy young adults, consuming a high-protein, lower-carbohydrate ultra-processed diet increases postprandial glucagon and peptide YY levels and decreases ghrelin levels compared to a normal-protein, normal-carbohydrate ultra-processed diet.
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.
In healthy young adults, eating a diet high in protein and low in carbohydrates made from ultra-processed foods raises glucagon and peptide YY levels and lowers ghrelin levels after meals compared to a diet with normal amounts of protein and carbohydrates made from ultra-processed foods.
See the scientific wording
In healthy young adults, consuming a high-protein, lower-carbohydrate ultra-processed diet increases postprandial glucagon and peptide YY levels and decreases ghrelin levels compared to a normal-protein, normal-carbohydrate ultra-processed diet, suggesting a hormonal mechanism for reduced energy intake.
Eating more protein and fewer carbs makes the stomach and intestines release less hunger hormone and more fullness hormones. The food also takes longer to chew, which tells the brain to feel full sooner. Together, this reduces how much a person eats.
What the research says
1 studyStudy: Short-term effects of high-protein, lower-carbohydrate ultra-processed foods on human energy balance
This study found that when young adults ate ultra-processed meals with more protein and fewer carbs, their bodies released less of the hunger hormone (ghrelin) and more of the fullness hormones (glucagon and peptide YY) compared to meals with normal protein and carbs. This helps explain why they ate fewer calories.
