Most people’s lives are shaped by an everyday routine from Monday to Friday. They leave the house in the morning, spend most of the day at work, university or school and return home in the late afternoon or evening. For many people Friday evenings bring on the long-awaited weekend, with plans for both leisurely and exciting activities. These few days each week can especially play a part in the emergence of overweight and obesity. Diverse tasks during the week generally ensure a constant amount of physical activity for people and simultaneously limit time for eating. During the week it is also easier for dieters to follow a diet or to exercise. With the beginning of the weekend, many people want to unwind and reward themselves for the working week, so they use the free time to have excessive meals at home or visit restaurants with family and friends. People are also often tempted to break their diet or exercise programme on a weekend and resume it again only in the following week. As e
Billions of bacteria and microorganisms populate the human body. Their amount exceeds that of the body cells in the intestine by tenfold, while the intestinal bacteria on their own account for around 1.5 kg of a person’s body weight. The entirety of our microorganisms, living on and in the body, are referred to as a microbiome. This is unique for every individual and is primarily acquired during pregnancy and birth, as well as through breastfeeding and the intake of solid food. Its composition modifies over the course
Bioimpedance analysis (BIA) is a method to determine a person’s body composition, for which the fields of medicine, fitness and nutrition have utilized more progressively lately. As it is an indirect method, it fundamentally depends on the applied mathematical equations used to calculate the body composition, taken from measurement parameters. The development and validation of these equations is a complex and time-consuming process, but it ultimately determines the accuracy of a BIA device. The basis for the bioimpedan
Bioimpedance analysis (BIA) is an established method for determining a person’s body composition. The analysis measures meaningful conclusions about the general, nutritional and hydration state, which can directly influence the treatment of many diseases. Since the BIA is an indirect process, the accuracy of a device's measurement is based on the right algorithms and reference methods, which are used to validate it. Bioimpedance analysis uses a weak AC field to measure the electrical resistance of the bo
A DXA scan yields a 2-dimensional image of the body. Calculating the body composition out of this can provide inaccurate results, because, for example, constant soft tissue thickness and water and protein fraction must be assumed.
In contrast to a DXA scan, in an MRI scan the body is "carved" into layers (slices). The volume of the subcutaneous fat (green) and visceral fat (yellow), as well as of the muscles (red), can be very accurately determined from the individual strata. (This picture illustrates the method; …
Being overweight or even obese has become a global health issue, one which is spreading rapidly, affecting large parts of the population in many places around the world. Along with this development, it is becoming increasingly difficult for people to recognize excess weight and give it the necessary attention. By now, every third person is overweight. According to the World Health Organization (WHO), about two billion adults and almost 400 million children and adolescents were affected by overweight (BM
