Effects of Ovariectomy and 17<i>β</i>-Estradiol Replacement on the Activity of Dopamine D2 Receptors in the Selection of Macronutrients Carbohydrates, Lipids and Proteins in Females Rats

17β-estradiol modulates the activity of D2 receptors in regulation food intake and body weight. The functional lack postmenopausal women could create a dietary imbalance cause weight gain. This study aimed to better understand interferences that exist between 17β-estradiol, selection carbohydrate, fat protein consumption, as well their consequences on gain by using an animal model menopause. Ovariectomy exacerbates consumption foods rich lipids. Thus confirming inhibitory action (E2) these types foods. stimulates gain, which is promoted high caloric content not amount consumed. Our results showed direct involvement choice. choice would be made according two (2) isoforms receptors. D2/BR isoform directs towards carbohydrate without causing While D2/SUL, promotes increase In women, ratio receptor ensure energy homeostatic balance, stabilizing
