G protein-coupled receptor kinases (GRKs) phosphorylate specific sites at the receptor C-terminal tail, providing binding sites for -arrestins (van Gastel et al., 2018)
This is an important distinction between both peptides because Ghrelin is responsible for initiating the breakdown of fat for use as energy as well as preventing the breakdown of muscles
While B12 itself doesnt cause weight loss, its role in energy metabolism means a deficiency could lead to fatigue and reduced physical activity, indirectly affecting weight management
Activity changes: Some experience fatigue or reduced energy on GLP-1s, leading to less physical activity and resistance training that would otherwise preserve muscle
