Staying Hydrated can Aid in Weight Loss

People who are obese are more likely to be inadequately hydrated. Drinking eight to ten glasses of water helps avoid overeating and helps with weight loss.

Simple changes in the diet can aid in weight loss. But a new study says that the changes are not linked to carbohydrates, fats or proteins.

The potential secret weapon? Water!

Water - Nutrient that Beats the Heat | Summer Nutrient-Water
Dehydration, acidity, loss of energy are common problems that often occur due to insufficient water consumption, especially in summer.

‘Eat foods high in water content such as fruits and vegetables to hydrate the body and shed extra kilos.’

People who are obese and have a higher body mass index (BMI) are more likely to be inadequately hydrated and vice versa, suggests new research from the University of Michigan published in Annals of Family Medicine.

"The link between hydration and weight is not clear. Our study further explains this relationship on a population level using an objective measure of hydration," says lead author Tammy Chang, M.D., MPH, MS, an assistant professor in the Department of Family Medicine at the U-M Medical School.

Although the correlation requires further probing, Chang noted that hydration has lately been considered a cornerstone of a weight-loss diet. "We often hear recommendations that drinking water is a way to avoid overeating because you may be thirsty rather than hungry," she says.

Contaminated Water Intake Among 1.8 Billion
Recent prevalent news reports points to the success of a United Nations' goal of notably bettering access to safe drinking water around the world.

Chang and colleagues looked at a nationally representative sample of 9,528 adults from the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey (NHANES). Roughly a third of the adults, who spanned ages 18 to 64, were inadequately hydrated.

The study suggests that people with higher BMIs - who are expected to have higher water needs - might also demonstrate behaviors that lead to inadequate hydration.

Obesity Does Not Increase Insulating Effects
Nearly half of the calories we consume are burned to maintain the body temperature. So, will excess fat in the body keep us warm during colder temperatures?

Authors note that because the data is cross-sectional, they cannot say that inadequate hydration causes obesity or the other way around. But their findings highlight an important relationship between the two.

Chang says eating healthy foods high in water content, such as fruits and vegetables, can improve hydration status though more studies are needed to know whether hydration status can influence weight.

More Than Half A Billion Obesity Rates are Underestimated
New tools are being developed to estimate the rates of obesity by taking a closer look at the ways that people's bodies are built in different places around the world.

"Hydration may be overlooked in adult weight management strategies," says Chang, who is also a member of the U-M Institute for Healthcare Policy and Innovation (IHPI).

"Our findings suggest that hydration may deserve more attention when thinking about addressing obesity on a population level. Staying hydrated is good for you no matter what, and our study suggests it may also be linked to maintaining a healthy weight."
