At the heart of weight management is the ability to appropriately regulate energy intake. A key factor in regulation of consumption is satiation, the process by which an eating bout ends. Quicker onset of satiation may result in decreased consumption, which is important in achieving an adequate energy balance. Negative energy balance, in which energy intake is less than energy expenditure, is required for weight loss; however, there are challenges with increased hunger and decreased satiation as energy intake is decreased.
