Absence of cardiac arrhythmias during a very-low-calorie diet with high biological quality protein.
Fourteen women who were at least 50 lb (22.7 kg) overweight entered the 15 week study which included 4 weeks of 1200 cal (5028 J) balanced diet followed by 7 weeks on a very-low-calorie diet (VLCD) and 4 weeks of refeeding. During the VLCD high biological quality protein (poultry, fish) and recommended supplements of vitamins, minerals and water were used. With the exception of week 5 and 14, 25-h Holter monitorings were done weekly. During the initial 4 weeks, 2 patients showed disturbances of cardiac rhythm and were discharged from the study. Twelve patients completed the trial without any clinically significant changes in cardiac rhythm. The 12 lead ECGs remained normal in all patients throughout the study. The average weight loss was 46 lb (20.9 kg) and the whole program was well tolerated. It is concluded that seven weeks of VLCD with high biological quality protein and recommended supplements appears to be a safe method for weight reduction for severely obese patients.
