Weight loss in mice fed on a low protein diet. Groups of BALB/c (n =5) mice were fed with a low protein diet (=malnourished (MN) group, 0.7% protein) or normal diet (=control group, 14.4% protein) for 16 days. Their weight was measured at regular intervals. Data show the results of one representative experiment out of five independent experiments. Results are expressed as mean with 95% CI.
