吃得超过维持体重所需的量在生理上会受到微弱的抵制，因为食欲不会密切跟踪身体能量平衡。限制能量摄入的是肠道容纳和处理所吃东西的能力。当肠道排空时，我们准备再次进食。我们通常将这种缺乏饱腹感称为“饥饿”，但在这种状态下，即使时间延长（例如错过一两顿饭），我们的精神和身体表现也不会受到影响，因为身体能量储存被动员起来维持对大脑和肌肉的能量供应。我们通过讨论关于不吃早餐的影响的研究来说明这一点。与传统观点相反，似乎不吃早餐会导致每日总能量摄入减少，并且不会损害认知功能（在营养充足的个体中）。然而，少吃一顿或少吃一顿的问题是，我们错过了（一些）吃的乐趣（食物奖励）。在目前的研究中，我们正在研究如何抵消减少奖励价值的较小的食物部分，例如，改变风味强度，食物品种和单位大小，以保持整体用餐满意度，从而减少或消除随后的补偿性饮食。
Eating more than is required to maintain bodyweight is weakly resisted physiologically, as appetite does not closely track body energy balance. What does limit energy intake is the capacity of the gut to accommodate and process what is eaten. As the gut empties, we are ready to eat again. We typically refer to this absence of fullness as ‘hunger’, but in this state, even when it is prolonged (e.g. by missing one or two meals), our mental and physical performance is not compromised because body energy stores are mobilised to sustain energy supply to our brain and muscles. We illustrate this by discussing research on the effects of missing breakfast. Contrary to conventional wisdom, it appears that missing breakfast leads to a reduction in total daily energy intake and does not impair cognitive function (in adequately nourished individuals). The problem with missing a meal or eating smaller meals, however, is that we miss out on (some of) the pleasure of eating (food reward). In current studies, we are investigating how to offset the reduced reward value of smaller food portions, by, for example, altering flavour intensity, food variety and unit size, in order to maintain overall meal satisfaction and thereby reduce or eliminate subsequent compensatory eating.
