Does Higher Protein Intake Boost Satiety in Resistance Training?
Research Link: https://pubmed.ncbi.nlm.nih.gov/30597865/ Summary: In a short-term energy deficit, high protein intake does not provide additional satiety for resistance-trained individuals Key Findings: High protein intake did not provide additional satiety during a short-term energy deficit. There were no significant differences in satiety, hunger, or desire to eat between the two protein levels. Absolute ghrelin levels significantly decreased post-meal with the PROMOD diet. PYY levels increased after high-protein meals in both PROMOD and PROHIGH. The desire to eat was more suppressed after meals in the PROMOD diet. PROHIGH did not offer additional satiety benefits compared to PROMOD. High-protein diets do not increase satiety over the long term. Changes in ghrelin and PYY were more pronounced with the PROMOD diet. Once protein needs are met, extra intake does not significantly increase satiety. Fiber-rich carbohydrates may maintain satiety better than additional protein. Conclusion: 1.8g/kg of protein intake is sufficient to maintain satiety. High-protein diets offer no additional satiety benefits. Ghrelin and PYY responses were more favorable with the PROMOD diet. Excessively high protein intake is not effective. Fiber-rich carbohydrates are more beneficial for satiety.
