The study, conducted by Viren Ranawana and Professor Jeya Henry of the Functional Food Centre at Oxford Brookes University, is the first of its kind to compare the compensation effect of liquid calories on short-term energy consumption, by gender.
During the research, male and female subjects consumed orange juice from concentrate, semi-skimmed milk, a sugar-sweetened fruit drink, or a calorie-free fruit drink, one hour before their lunchtime meal. Each group was then provided with a self-selection buffet, including a variety of foods in ample quantity, and the amount of energy they then freely consumed was analysed and compared.
The results show that liquid calories are detected by the body and compensated for at the next meal. Both men and women who consumed a drink containing calories in the morning ate less energy for lunch, compared to when they had a calorie-free mid-morning drink. However, while the mean total energy intakes for men following all four beverages were similar, women demonstrated a trend for greater energy intake following the three caloric drinks compared to the control. Thus, using a preload paradigm differing in protocol to previously reported studies, the new research gives evidence of a possible energy compensation dysregulation in women compared to men.
Professor Henry, of Oxford Brookes University, said: "It is important to understand if the growth in caloric beverage consumption is contributing to the increased prevalence of obesity and diabetes. It has been suggested that sugars provided in liquid form encourage 'passive over-consumption' of energy from food, but this study shows that the body does compensate in the short term. Further research is now needed to understand the mechanisms involved and whether the body also compensates for liquid calorie consumption in the long term."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
