Diets consisted of 1,200 kcal/d for 1-wk and 1,600 kcal/d for 9 wks. Diets were 55% CHO, 15% P, and 30% F (HC) or 7-15% CHO, 55-63% P, and 30% F (HP). Exercise groups participated in a supervised fitness program (3-d/wk) that involved 30 min of circuit-style resistance training interspersed with callisthenic exercises.The results are equivocal, the HOMA, i.e. an index which measures insulin resistance and sensitivity "increased to a greater degree in the HP group (1.48±0.4) while glucose decreased to a greater degree in the HH group (-13.3±5 mg/dL).", meaning that the high protein diet helped to get off / alleviate the carbohydrate addiction, while the high carb diet made things even worse. These results lead the scientists to conclude:
A HP diet during resistance training promotes more favorable changes in HOMA and individuals with higher HOMA values experience a greater reduction in fasting glucose levels.
