Dietary fat and not calcium supplementation or dairy product consumption is associated with changes in anthropometrics during a randomized, placebo-controlled energy-restriction trial

摘要: Insufficient calcium intake has been proposed to cause unbalanced energy partitioning leading obesity. However, weight loss interventions including dietary or dairy product consumption have not reported changes in lipid metabolism measured by the plasma lipidome. The objective of this study was determine relationships between supplemental with lipidome and body composition during restriction. A secondary explore among calculated macronutrient restricted diet lipidome, Overweight adults (n = 61) were randomized into one three intervention groups a deficit 500kcal/d: 1) placebo; 2) 900 mg/d supplement; 3) 3-4 servings products/d plus placebo supplement. Plasma fatty acid methyl esters cholesterol ester, diacylglycerol, free acids, lysophosphatidylcholine, phosphatidylcholine, phosphatidylethanolamine triacylglycerol quantified capillary gas chromatography. After adjustments for protein (g/d) intake, there no significant effect treatment on weight, waist circumference composition. did differ groups.
