Protein intake does not affect insulin sensitivity in normal weight cats.

The article presents a comparative study on insulin sensitivity, insulin secretion, and plasma leptin and insulin-like growth factor-1 (IGF-1) in cats fed diets differing in protein and carbohydrate content. The study utilized normal-weight cats and were assessed with insulin sensitivity and insulin secretion, plasma leptin and IGF-1 level. Findings show that high protein diet do not affect insulin sensitivity or insulin secretion in reaction to glucose in normal-weight cats and present lower IGF-1 level in opposition to results from previous studies. Furthermore, plasma leptin is consistent with the normal weight of the cats. However, further analysis is needed to obtain specific results on the effects of diets on metabolic equilibrium of glucose in cats.
