However, there is limited real-world evidence comparing the effects of once-weekly (OW) GLP-1 RAs and dipeptidyl peptidase-4 inhibitors (DPP-4is)
Effectiveness In a controlled clinical trial, tirzepatide led to 20% reduction in body weight over a 72-week period
The difference in comfort between 29G and 30G is real but subtle
However, more long-term studies are needed
The decision to include seven participants was based on practical considerations and the standard practices for similar studies in sports science, particularly when measuring physiological variables like heart rate, respiratory quotient, and perceived exertion, which require high-quality, individualized data
GLP-1 receptor agonists like semaglutide and tirzepatide target the underlying metabolic drivers of weight gain: they reduce appetite signals in the brain, slow digestion so you stay full longer, improve insulin sensitivity, and reduce the hormonal hunger signals that make sustained dieting so difficult
