Phosphorus ingestion with glucose was reported to stimulate the postprandial peripheral uptake of both phosphorus and glucose, a process that favors energy production. The aim of this study was to determine whether phosphorus ingestion with a meal can affect energy metabolism.
Overnight fasted men (eight lean and seven obese) consumed a high-carbohydrate meal (648 kcal) with either placebo or phosphorus (500 mg) tablets in a random order. Energy expenditure and substrate oxidation were monitored for 240 min using ventilated hood indirect calorimetry.
Phosphorus ingestion with a meal increased the postprandial energy expenditure of both lean and obese individuals (P < 0.001), although in different patterns. Alterations in postprandial substrate oxidation was highly noticeable from time 120 min onward, where phosphorus-treated lean participants exhibited a significant decrease in respiratory quotient.
Phosphorus ingestion with a high-carbohydrate meal alters postprandial energy metabolism mainly by enhancing postprandial energy expenditure that may ultimatly favor weight loss.
有报道称，葡萄糖摄入磷可刺激餐后外周对磷和葡萄糖的摄取，这一过程有利于能量产生。本研究旨在确定随餐摄入磷是否会影响能量代谢。
8 名瘦人和 7 名肥胖男性在夜间禁食后，随机顺序摄入含有安慰剂或磷（500mg）片的高碳水化合物餐（648 千卡）。使用通风罩间接测热法监测 240 分钟的能量消耗和底物氧化。
随餐摄入磷可增加瘦人和肥胖个体的餐后能量消耗（P <0.001），尽管模式不同。从 120 分钟开始，餐后底物氧化的变化非常明显，其中磷处理的瘦参与者的呼吸商显著降低。
随高碳水化合物餐摄入磷可改变餐后能量代谢，主要通过增强餐后能量消耗，这可能最终有利于减肥。
