Protein and energy restriction lower IGF-1 by reducing hepatic growth hormone receptor expression and IGF-1 synthesis; refeeding restores it. In children with malnutrition IGF-1 is low and recovers with treatment, and in anorexia nervosa it is low despite high growth hormone. Among macronutrients, protein has the clearest effect. These findings are consistent across decades.
Caloric restriction in rodents lowers IGF-1 and extends life, which is part of the longevity story.
Whether habitual high protein intake in adults raises IGF-1 enough to matter for cancer or mortality. Cohort associations exist, including the 2014 analysis, but confounding by other dietary and lifestyle factors is substantial, the age reversal is hard to explain mechanistically, and intervention studies are short. Dairy associations are consistent but modest.
The question is open and this page states it as open.
Because a reader of the IGF-1 literature will meet dietary claims and should know which rest on physiology and which on association. It describes no use of the pack.
