According to a study published by Medical News Today, one who substitutes alcoholic beverages for water is linked to a modest amount of weight loss over a 4 year period. This was a study that included 15,765 adults that analyzed their dietary habits within a 7 year period.
Obesity, which many scientific and fitness experts say meets the definition of "disease", is a global epidemic, with about 2.8 million people due each year due to complications associated with obesity and being overweight. Once a disease that was mainly present in wealthy countries, obesity has been more comon in low and middle income areas of the world.
In this particular study, it states that energy imbalance is the main cause of obesity, mixed with a sedentary lifestyle, and major consumption of calories have contributed to one's chances of becoming obese. High intakes of alcoholic and high-sugared liquids are major contributors to weight gain. This would make sense since it's been proven that one is less likely to be full from liquid foods in comparison to foods that are solid.
The subjects of this study replaced each alcolic or sugary drink with a glass of water as substitution. Using a mathematical model, researchers concluded that REPLACING ONE BEER TIED TO 20% PERCENT LOWER RISK OF OBESITY. In the same study replacing a sugary drink with a glass of water lowered one's obesity risk by 15%. Researchers also discovered a link between substituting beer with a glass of water, which concluded to a modest amount of weight loss over a 4 year period.
