Obese people feel full sooner than people of normal weight

08.04.2014

Obese people take less time to feel full than those of normal weight. Despite this, they consume more calories. A faster speed of eating could play an important role in obesity, according to a study funded by the Swiss National Science Foundation.

The number of people in the world who are obese has doubled since 1980. Attempts to halt the progress of this pandemic are reliant on more accurate knowledge of how obesity occurs.

This is what a research group led by Christoph Beglinger at the University Hospital in Basel aimed to find out by comparing feelings of satiation among people of normal weight and those who are obese. In their study (*), the researchers conclude that obese people eat faster. The obese take less time to feel full than people of normal weight, and although they spend less time eating, they consume more calories.

Time to satiation

Christoph Beglinger and his team asked twenty people of normal weight and twenty people who were obese to consume a nutritional drink in the morning, on an empty stomach. The test subjects were allowed to drink as much as they wanted, and as quickly as they wanted. Every three minutes they were required to indicate how full they felt.

On average, the obese people reported feeling full after just ten minutes, four minutes earlier than those of normal weight. However, during this ten minute period they consumed on average approximately 85 kcal per minute, compared with around 50 kcal per minute consumed by the test subjects of normal weight. Therefore, despite the shorter period of consumption, obese people consumed around 140 kcal more before they felt full.

Eat slowly

“Eating even just 100 kcal a day more than the recommended amount can cause weight gain,” write the researchers in their study. “For this reason, the speed of eating is a potential contributing factor in obesity.” Although making changes to people’s eating habits is difficult, the new results indicate that treatments focussing on such approaches are correct. “Eating slowly is not only healthy, but it should also help you lose weight,” explains Beglinger.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
