Interactions between protein leverage, variety, and dietary carbohydrate and fat content in the control of energy intake in humans

大多数试图了解人类对肥胖的脆弱性的尝试都集中在脂肪和碳水化合物上，然而最近的研究表明蛋白质具有强大的作用：当饮食中蛋白质浓度较低时，我们会摄入更多卡路里。但蛋白质如何与饮食的其他方面相互作用，特别是现代环境中种类繁多的食物以及脂肪与碳水化合物的平衡？我们将使用对照试验来研究这些因素是如何导致过量能量摄入的。

Most attempts to understand human vulnerability to obesity have focussed on fat and carbohydrate, yet recent studies have shown a powerful role for protein: we eat more calories when dietary protein concentration is low. But how does protein interact with other aspects of the diet, notably the prodigious variety of foods available in modern environments and the balance of fat to carbohydrate? We will use controlled trials to investigate how these factors contribute to excess energy intake.
