Satiating Effect of High Protein Diets on Resistance-Trained Individuals in Energy Deficit

Equally so, very high protein intakes, exceeding these recommendations, may not only negatively impact on an athletes’ well-being and reduce the effort given to training, but also carries the risk of displacement of other nutrients. [...]the aim of this study was to compare the satiating effect of two diets with a different protein content in resistance-trained subjects in energy deficit, participant well-being and training motivation. In the current study, nutrient composition of the test-meals remained the same across all testing sessions. [...]although absolute changes in PYY were not reportedly different between dietary interventions, the relative change difference indicated that both the decrease in caloric intake, along with the higher protein content of the test meal resulted in acute increases in PYY concentrations over the 2-h monitoring period for PROMOD. [...]maintenance of training performance and lean gains during periods of acute or chronic energy deficit should be considered to determine whether a PROMOD diet sustains beneficial responses in resistance-trained athletes. 5. Furthermore, a PROMOD diet favorably improved hormonal responses to a test-meal compared with a PROHIGH diet. [...]as long as training motivation/ performance is not compromised during short-term energy deficit, moderate protein intakes (1.8 g·kg−1·d−1) are likely to be adequate for resistance-trained individuals.
