Differential susceptibility to obesity between male, female and ovariectomized female mice.

Background: The prevalence of obesity has increased dramatically. A direct comparison in the predisposition to obesity between males, premenopausal females, and postmenopausal females with various caloric intakes has not been made. To determine the effects of sex and ovarian hormones on the susceptibility to obesity, we conducted laboratory studies with mice.

Ethanol consumption does not promote weight gain in female mice.

Background: The prevalence of obese adult women has increased dramatically in the United States. Individuals consuming alcoholic beverages may obtain as much as 6-10% of their calories from ethanol; consequently, ethanol may contribute to a positive energy balance and weight gain in women consuming ethanol. The objective of these studies is to determine if ethanol consumption affects weight gain or body fat levels in female mice.
