"Eating more slowly may be a crucial lifestyle change to help prevent metabolic syndrome," study author Dr. Takayuki Yamaji, a cardiologist at Hiroshima University in Japan, said in a news release, NBC News reported.
"When people eat fast they tend not to feel full and are more likely to overeat. Eating fast causes bigger glucose fluctuation, which can lead to insulin resistance," Yamaji explained.
The researchers' preliminary findings were presented Monday at the American Heart Association's Scientific Sessions.
