| Research Abstract |
Generally, gorging pattern of eating has been thought to increase visceral fat deposition compared to nibbling pattern of eating. However, sufficient scientific proof has never been available. In the present study, we compared effects of meal frequency, once a day(gorging group) and thrice a day (nibbling group), on energy metabolism, visceral fat deposition and hepatic lipid metabolism in rats fed a high fat diet. Respiratory quotient (RQ) was higher and fat consumption was lower in the gorging group compared with the nibbling group. Total energy consumption was the same between the two groups. Final body weight and visceral fat weight were almost the same between the groups. However, concentrations of blood glucose, serum insulin, serum adiponectin and hepatic triacylglycerol were influenced by different meal frequency. These observations suggest that visceral fat deposition is not influenced by meal frequency at least in this experimental condition, but carbohydrate and lipid metabolisms are altered by eating habits.
