I have never actually studied the effect of menopause on weight gain, so this could be a potential topic for research. Menopause, is due to decline in hormones responsible for normal menstrual cycles, however, I am quite sure as to how this reduction in hormones contribute to weight gain. What I can recommend at the moment, however, is that you treat your weight gain similarly like everyone with weight issue. First thing to remember that the recommendation for a safe and healthy weight loss is to loose 1 to 2 lbs weekly. You can do this by in-cooperating aerobic exercises(like walking),strength training, and consuming a balance healthy diet(control your portion) each meal. aerobic exercise and moderate use of weights will help you to convert those extra pounds of fat into lean muscles. You will also be able to develop more fat burning enzymes which will help to burn the fat. Finally, you will be able to increase your basal metabolic rate even when resting, when you exercise regularly(say 3o minutes minimum, 4-5 days wkly).
