This means that if youve wondered why some people seem to eat whatever they want without gaining weight, it may be due to their faster metabolic rate
For example, some people lack a protein called intrinsic factor , which helps with the absorption of vitamin B12

In prepubertal children with advanced CKD and severe growth retardation, GH administration has shown significant benefits, leading to increased serum IGF-1 levels.97 However, despite improved growth in children treated with GH and the non-apparent progression of renal damage, bone maturation seems to be unaffected despite of the increased plasma IGF-1 levels after 6 months, maybe due to the concomitant decrease of IGFBP-1 and increase of IGFBP-3, which occurred in a lower extent that the IGF-1 changes.98 In the same way, circulating levels of IGF-1 are not correlated with bone formation parameters in non-dialysis CKD patients, which apparently excludes a role of the IGF-1 in bone turnover.99 Recent studies have demonstrated that low serum IGF-1 levels are associated with lower weight and bone mineral density in pediatric CKD patients.100 Importantly, a combination of recombinant GH and IGF-1 has been found to be more effective in preventing growth retardation than GH alone, suggesting an impaired response to the GH effect on IGF-1 stimulation.101 In a study of young rats with renal insufficiency, despite having similar serum GH levels, exhibited lower IGF-1 concentrations, which may contribute to bone growth retardation
