摘要：We performed a pre/post-interventional study with participants as self-controls to evaluate the effects of consuming an evening-only low-carbohydrate meal (LCM) at 1800 h on biochemical measures of glucose and lipid metabolism. Study participants comprised 14 healthy men (age range, 20-29 y) who, consumed standard test meals (STMs) or LCM at 1800 h. Blood samples were collected at fasting, and at 60-, 120-, and 240 min after the start of the meals. The 60-min postprandial levels and the area under the curve (AUC) 0-120 min for plasma glucose were significantly lower after the LCM than after the STMs. The 60- and 120-min postprandial levels and the AUC 0-240 min for plasma insulin were significantly lower after the LCM than after the STMs ( p <0.01). Postprandial triglyceride (TG) levels at 120- and 240 min and the AUC 0-240 min were significantly higher after the LCM than after the STMs ( p <0.05, p <0.01, and p <0.05, respectively). The interleukin-6 levels were significantly higher 240 min after the STMs than before the meals ( p <0.05), but not after the LCM. In these healthy volunteers, consuming an LCM at 1800 h suppressed postprandial hyperglycemia and insulin secretion; however, postprandial TG increased. Consuming an LCM at 1800 h was beneficial as it inhibited elevation of blood glucose; however, it may also increase the risk of arteriosclerosis through increasing TG levels.
