The average glass of red wine contains around 125 calories, and a bottle would usually hold five glasses - or around 600 calories. A 13-year Harvard University study containing 20,000 women found that those who drank half a bottle of wine on a daily basis were 70% less likely to develop obesity. These two pieces of information seem to clash, as adding another 300 calories to your diet on a regular basis should cause you to gain weight, not lose it, but the results seem to speak for themselves.
The University College Medical School of London conducted an eight-year study with 43,500 female participants and found that those who drank a couple of glasses on a daily basis were 24% less likely to put on weight compared to those who abstained from alcohol.
Furthermore, a 10-year study held by the CDC found that of the 7,230 people it studied, the drinkers gained less weight than non-drinkers, and concluded that alcohol intake does not increase the risk of obesity.
