Post-dinner snacking leads to weight gain through the increased caloric intake (Waller, 2004). Nocturnal snacking increases sugar levels. When sugar levels are increased, hormones such as insulin, ghrelin, and leptin, are activated and specific systems in the body begin to work (Kalergis, 2003). As the body becomes more alert through glucose metabolism, it may be difficult to switch off and fall asleep (Kristen, 2007). As shown in our other document, inadequate sleep causes weight gain. Women and men consume 15.3% and 9.2% more calories when deprived of sleep, respectively (St-Onge, 2011).
