Hi Robert,
Alcohol provides 7 calories per gram and can lead to excess calories resulting in weight gain. One 4 oz glass of wine has around 100 calories. If you reduced your wine intake to 1-4 oz glass a day, you would reduce your daily calorie in take by 200 calories. This would lead to a gradual weight loss of 1 pound every 2-3 weeks. Slow going, but would make a difference.
Studies indicate that alcohol can stimulate your appetite, another pro for cutting back to 4 oz/day.
