Igf 1 hypothyroidism and weight: Interactions between GH, IGF-I, Glucocorticoids, and Thyroid Hormones during Skeletal Growth

Studies suggest that high-protein diets can increase IGF-1 levels, but higher fat intake, in particular saturated fat, can lead to lower levels. However, at the presence of goiter IGF-1 levels decrease.
