Commonly used adjectives describe the novel class of anti-obesity drugs, including Ozempic, Wegovy, and Mounjaro. These prescription medications simulate the actions of gut hormones, stimulating insulin release to lower post-meal blood sugar and slow stomach emptying. Their profound appetite-suppressing effects and weight loss facilitation have resulted in manufacturers struggling to meet soaring demand.\r\n\r\nREAD: \u201cShocking: American Heart Association Links Daily Marijuana Use to 34% Higher Risk of Heart Failure\u201d\r\n\r\nDespite the weight loss induced by these drugs, it falls short of providing comprehensive health benefits. Consequently, individuals using these medications must recalibrate their lifestyle factors, emphasizing physical activity and exercise, as suggested by John Jakicic, Ph.D., a research professor at the University of Kansas Medical Center's Division of Physical Activity and Weight Management.\r\n\r\nIn one of the pioneering peer-reviewed articles on how physical activity integrates into obesity treatment with these anti-obesity medications, Jakicic and Renee Rogers, Ph.D., senior scientist in the same division, propose that these drugs necessitate a reassessment of the approach to physical activity. Their article, published in the Obesity journal of The Obesity Society on October 17, highlights Jakicic's insights shared in a recent Morning Medical Update by The University of Kansas Health System.\r\nAnti-Obesity\r\n"These medications have altered our perspective on activity," Jakicic asserted. "They handle the weight loss, prompting us to focus not on how much activity is needed for more weight loss, but on the additional benefits that activity provides, which these weight loss medications do not."\r\n\r\nThese benefits encompass enhanced cardiovascular fitness and muscle strength, accruing from exercise even without substantial weight loss. Jakicic emphasized the significance of comprehending that weight loss doesn't diminish the need for physical activity. Hence, patients and clinicians alike should acknowledge this paradigm shift.\r\n\r\nThe researchers suggest that the current recommendation of 200 to 300 minutes of exercise per week for weight loss might no longer be applicable with these new medications. Instead, they propose the public health guideline of 150 minutes per week of moderate-intensity physical activity and two days of resistance exercise to mitigate sedentary behavior as potentially adequate for individuals using anti-obesity drugs.\r\n\r\nAnother complexity lies in the loss of lean mass accompanying weight reduction, a phenomenon seen more prominently with these medications compared to weight loss through diet and exercise alone. Jakicic explained that while it seems intuitive to counter this loss with more exercise, particularly resistance training for muscle building, it is crucial to recognize that lean mass encompasses more than just muscle. The extent to which the lean mass loss during medication-assisted weight loss constitutes muscle mass remains uncertain.\r\n\r\nMoreover, even when resistance exercise is incorporated into a weight loss program, some muscle mass is still lost. Jakicic and his team emphasized the importance of enhancing muscle quality rather than solely focusing on increasing muscle mass. He stressed that improving muscle quality results in more functional muscles, leading to better control of insulin and glucose levels.\r\n\r\nThe Physical Activity and Weight Management division at KU is initiating various studies concerning these new medications, weight loss, and physical activity. Among these efforts is a pilot study led by Rogers, supported by the Kansas Center for Metabolism and Anti-Obesity Research, investigating the effectiveness of aerobic and resistance training in individuals using anti-obesity drugs.\r\n\r\n"We aim to generate evidence that enhances the care for individuals utilizing these medications," Jakicic affirmed. "While we have a current perspective, our ongoing research endeavors may reshape this viewpoint as we strive to improve future treatments."
