| Abstract: | Dietary protein alters circulating amino acid (AAs) levels and higher protein intake (HP) is one means of losing weight. We examined 34 overweight and obese women (57?±?4 years) during 6 months of energy restriction (7.3?±?3.8% weight loss) divided into groups consuming either normal protein (NP; 18.6 energy% protein) or HP (24.3 energy% protein). There was a reduction in fasting serum glucogenic AAs (p?=?0.015) that also associated with greater weight loss (p?<?0.05) in the HP group, but not in the NP group. These findings have implications for nutrient prioritization during energy restriction. |
