title: Increased plasma levels of zinc in obese adult females on a weight-loss program based on a hypocaloric balanced diet.
abstract: Zinc is required for many biological functions including DNA synthesis, cell division, gene expression and the activity of various enzymes in humans and animals. Zinc concentrations in the plasma and erythrocytes are lower and urinary zinc excretion and serum insulin levels are higher in subjects with obesity. The effects of a weight-loss program based on a hypocaloric balanced diet were investigated on 23 obese females, who had a body mass index of more than 25.0 and had dieted for 6 months at the Nutrition Clinic, Institute of Nutrition Sciences, Kagawa Nutrition University, Tokyo, Japan. The subjects ranged in age from 29 to 76 (54.3 +/- 13.0) years old. The hypocaloric balanced diet significantly reduced the body weight, body mass index, body fat percentage and amount of body fat with a slight lowering of blood pressure and plasma levels of triglyceride. Interestingly, the plasma concentrations of zinc were markedly enhanced at the end of the program.
