An investigation of physiological adapatations contributing to weight regain after weight loss

为什么我们会发胖，为什么很难保持减肥，这是这项研究的重点。我们可以在短期内通过自愿控制（节食）来调节食物摄入量，但我们长期控制食物摄入量的能力更为复杂。许多蛋白质共同调节食物摄入，就像我们血液中的循环因子一样。在减肥之前和之后，将检查受试者的饥饿感和饱腹感，以便我们可以确定参与成功减肥的途径。

Why we gain weight, and why it s hard to maintain weight loss, is the focus of this study. We can regulate food intake by voluntary control in the short term ( dieting ), but our long term ability to control food intake is more complex. Many proteins work together to regulate food intake, as do circulating factors in our blood. Before and after weight loss, subjects feelings of hunger and satiety will be examined so that we can identify pathways that are involved in successful weight loss.
