Drinking water supports body weight reduction.
Water and obesity
Obesity is a major concern in our modern world. In recent years, it has become a real epidemic. Obesity among both adults and children is a serious threat with multiple health-related consequences. A research from 2014 showed that 15,6% of women and 18,1% of men suffer from obesity. Even more people are said to be overweight (Body Mass Index > 25 kg/m2 -1) – 30,1% of women and 44,1% of men. Comparing it to a research from 2004 (women – 14,2%, men – 19,8%), demonstrates that a number of overweight population doubled over the last decade. Not only does this problem affect adults but it is also easily visible among children, however, the numbers are volatile as they depend on age and sex. It is also true that obesity among children decreases with age. Among 11-year-olds it was 21% for boys and 21% for girls. Among 13-year-olds 26% and 13%, and among 15-year-olds it decreased to 22% and 7% accordingly. Obesity and being overweight were more frequent among boys (19,2%) than girls (10,4%) (according to: Bureau of Research, Chancellery of the Sejm, 15th March 2017).
Nowadays, obesity is viewed as a medical condition, which has a negative impact on physiological functions of a body. In addition, obesity is also a risk factor when it comes to many diseases and conditions such as cardiovascular disease, type 2 diabetes, arthrosis and some types of cancer.
As certain research show, drinking water can stimulate sympathetic nervous center, which theoretically, should lead to a faster metabolism (post-meal thermogenesis connected with digestive process). As a consequence, it contributes to an increase in daily energy expenditure. Although the idea of boosting thermogenesis due to water consumption is highly controversial, drinking large amounts of water is commonly recommended as a way of boosting body weight reduction in many diets.
While conducting an experimental study among overweight women, researchers have shown that activating sympathetic nervous system after drinking water may increase the expenditure of rest energy by 30% and may last for over an hour. However, this effect is reduced after drinking warmer water (37°C). It led to the suggestion that the rise in energy expenditure after drinking water is closely related to the fact that our body has to heat this water in order for its temperature to be equal to 36,6°C. After studying these conclusions, the authors claimed that the rise of water consumption of 1,5 litre a day, increased energy consumption by 200 kJ/daily, which is about 50 kcal.
Another study which aimed to assess the influence of consumed water on rest energy expenditure among overweight children confirmed the previous findings. It also showed that during 40 minutes after drinking cold water (10 ml/kg body weight), the transfer of rest energy increased by 25%. However, the idea of thermogenesis which is to be activated after drinking water is still doubtful and controversial. A few other publications show that water consumption has little or no influence on rising energy demand connected with thermogenesis.
Nowadays, nutritional awareness is becoming more and more visible in society, and yet obesity is still a major concern connected with public health and is more and more often associated with younger age groups. The world of science is still divided when it comes to the issue of relation between drinking water and energetic expenditure. Nevertheless, researchers agree that in most cases drinking water is crucial in staying healthy. In other words – you can never have too much water. It is important to pay attention to quality water, which can supply valuable minerals such as iodine, hydrocarbons, calcium, magnesium, sodium and potassium. Jantar Water is the definition of such a liquid – it is not only pure, but it also hydrates the body well and provides necessary electrolytes. Minerals that can be found there are mostly ions and their bioavailability makes them perfect for the body.
Hunger and thirst centres are located close to each other in human’s brain and that is why sometimes it is difficult to differentiate the right desire sent from it. But maybe instead of eating another donut, it would be enough to drink Jantar Water?! According to scientific research, water has negative calories and it accelerates body weight reduction.
