The large portion of the human body is water including brain and heart which accounts up to 73% water, our lungs contain up to 83% water, skin consists 64%, muscles and kidneys with 79% and bones have 31% water. Depriving the human body of water can lead to dehydration, which can result in many unhealthy consequences. Unfortunately, there are many men and women who don’t drink enough amount of water daily. The average Americans, for example, are not drinking enough water according this data gathered from a survey. At the same time, the obesity rate is in a rising trend.
Recently, one study1 published at Annals of Family Medicine in which researchers found a significant link between lack of water consumption and increased in obesity rate through BMI measurement.
We found a significant association between inadequate hydration and elevated BMI and inadequate hydration and obesity, even after controlling for confounders. This relationship has not previously been shown on a population level and suggests that water, an essential nutrient, may deserve greater focus in weight management research and clinical strategies.
Regardless of the continuous efforts on having a healthy diet and regular physical activity, the obesity rate is persistently climbing. Would this lack of water consumption a coincidence with the increase rate of obesity? Tammy Chang, assistant professor of family medicine at University of Michigan Medical School think it is not a coincidence. According to her;
There’s so much focus on food and exercise, but so much more than just food and exercise goes into weight.
This is not the only study that attempted to establish a link between water consumption and weight loss. In 201, one study2 found that drinking water prior to meals is also helpful for weight loss purposes. In a different study3 where researchers found that obese or overweight middle-aged and older adults increase their weight loss rate by drinking 2 cups of water before meals along with a hypocaloric diet.
There’s more. Another study 4 in which researchers found premeal water consumption is an effective weight control for older adults. However, in a different study5 researchers found that premeal water consumption is only helpful and effective for older adults, but not in younger subjects.
Drink More Water
Experts are advising us to drink more water. However, too much water is not a good thing either as it’s deadly causing intoxication. Too little, on the other hand, can lead to dehydration. So, what is the correct amount of water we should be consuming without getting intoxicated and/or dehydrated?
