Researchers at McMaster University in Canada have opened a state-of-the-art Energy Lab to investigate the mysteries of weight loss in both children and adults. The lab, the first of its kind in Canada, aims to uncover why some people lose weight more easily than others, why weight is often regained after loss, and how to improve the health of obese youth. Using advanced technology, the lab measures the calorie burn of study participants with greater precision than ever before. The researchers hope their findings will lead to new ways to help people with obesity maintain their weight loss more efficiently.
The Energy Lab, located at McMaster’s Centre for Metabolism, Obesity and Diabetes Research in Hamilton, Ontario, is specifically focused on studying energy expenditure in both children and adults. The lab measures the amount of energy burned by the body in performing bodily functions, as well as energy used for movement and metabolizing food after eating.
According to Dr. Gregory Steinberg, co-director of McMaster’s Centre for Metabolism, Obesity and Diabetes Research, one of the lab’s main goals is to understand why some individuals gain more weight than others, even when their diets are the same. By studying changes in calorie burn when people lose weight, the researchers hope to develop new methods to help individuals maintain their weight loss.
The lab utilizes cutting-edge technology to measure energy expenditure with remarkable precision and accuracy. This includes a unique sensor that measures the oxygen used and the carbon dioxide produced by study participants, allowing for precise calculations of energy expenditure and calorie burn. Study participants can spend time in an airtight room equipped with the sensor, allowing for measurement of their energy burn overnight or for shorter durations. The researchers can also determine whether the calories burned are predominantly from fat or carbohydrates.
The Energy Lab aims to fill a crucial gap in knowledge about energy expenditure in humans. While scientists have learned a great deal about this topic from studying animals, accurately measuring energy burn in humans has proven challenging. The researchers at McMaster University hope that their lab will provide valuable insights into the impact of energy expenditure on human health and contribute to the development of effective weight loss strategies.
Obesity is a pressing issue in Canada, with nearly two-thirds of adults and one-third of children and youth classified as overweight or obese, according to the Public Health Agency of Canada. The health consequences of obesity are significant, with obesity serving as a major risk factor for conditions such as diabetes, heart disease, kidney disease, and certain types of cancer. It is also associated with mental health issues and metabolic challenges in children, such as prediabetes and abnormal cholesterol levels.
The Energy Lab’s first study focuses on measuring how children burn energy throughout the day and its connection to overall health. The lab also plans to conduct a separate study on adults, investigating how anti-obesity medications, such as Ozempic, influence energy expenditure.
Dr. Katherine Morrison, a professor at McMaster’s pediatrics department and co-director at the Centre for Metabolism, Obesity and Diabetes Research, emphasized the importance of understanding the fundamental pathways that contribute to weight gain and loss. These pathways play a role in various aspects of metabolism, including the signals from the gut to the brain that regulate hunger and fullness. Understanding how these pathways change with weight loss and weight regain can provide valuable insights into developing effective weight management strategies.
The new Energy Lab at McMaster University represents a significant step forward in our understanding of weight loss and energy expenditure in both children and adults. With its cutting-edge technology and comprehensive approach, the lab aims to make groundbreaking discoveries that could have a significant impact on the health and well-being of individuals struggling with obesity. By shedding light on the mysteries of weight loss, this research has the potential to pave the way for more effective strategies to help individuals achieve and maintain a healthy weight.
