homeostasis/metabolism
N
• mice exhibit normal feces energy content, glycosuria, metabolic parameters (body temperature and free triiodothyronine or adiponectin serum levels), insulin sensitivity and glucagon levels
• in mice fed a high fat diet
• however, mice supplemented with phosphorylated creatine exhibit normal obesity when fed a high fat diet
• decreased urine levels of creatine, creatinine and guanidine acetate
• in mice fed standard chow
• however, mice supplemented with phosphorylated creatine or fed a high fat diet exhibit normal circulating cholesterol levels
• increased glucose clearance through GLUT4 in skeletal muscle and white adipose tissue
• after pyruvate injection
• after glucose challenge, when fed ad libitum or fed a high fat diet
• however, levels are normal under fasted conditions
• impaired in the liver
• in mice fed standard chow or a high fat diet

growth/size/body
N
• mice supplemented with phosphorylated creatine (Cr) exhibit normal body length, body weight, BMI and body composition
• from 4 weeks onward
• in mice fed a high fat diet
• however, mice supplemented with phosphorylated creatine exhibit normal obesity when fed a high fat diet

adipose tissue
• in mice fed a high fat diet
• in the intestinal, subcutaneous and epigonadal white adipose tissue of mice fed a high fat diet
• in mice fed standard chow or a high fat diet

behavior/neurological
• during the active dark period

liver/biliary system

muscle
