Infants have distinct metabolic capacities than adults
The rats were randomly divided into 4 groups (each group of 20 rats): group A1 (normal control group under normoxia), group A2 (normal control group under normoxia, received low-dose l-carnitine at 50 mg/kg), group A3 (normal control group under normoxia, received high-dose l-carnitine at 100 mg/kg), group B (plateau model control group, received injecting normal saline), group C (low-dose l-carnitine intervention altitude model group, received 50 mg/kg l-carnitine) and group D (high-dose l-carnitine intervention altitude model group, received 100 mg/kg l-carnitine)
After discontinuing treatment due to the temporary unavailability of the drug, she regained 7 kg in three months, increasing her body weight to 120 kg (body mass index 59.9 kg/m2)
This is higher than the standard dietary recommendation of 0.8 g/kg, because active weight loss creates a higher demand for amino acids to preserve lean tissue
