Whether continued GCGR-mediated energy expenditure explains the sustained trajectory is not yet formally characterised, but the mechanistic hypothesis is consistent with the animal data

Within this framework, absorption can be considered a metabolic control module: even when dietary composition appears adequate, altered gastrointestinal kinetics may reduce effective delivery of critical substrates, shifting metabolic constraint from nutrient intake to handling efficiency

3.4 Changing clinical and regulatory expectations Finally, shifts in clinical and regulatory expectations have altered the landscape in which peptide therapeutics are evaluated

Drugs like Ozempic and Wegovy may be covered by Part D if prescribed for diabetes management or cardiovascular disease
