Hi, I am looking for someone to write an article on effect of lack of sleep on weight gain among college students Paper must be at least 2000 words. Please, no plagiarized work! Short sleep, which is defined as sleep at night that is <. 5 hours for adolescents and adults and <. 9 hours of sleep for children (ages 5 to 12), has been correlated with obesity because sleep deprivation may increase body weight and body mass index (BMI) (Martinez et al., 2014. Westerlund et al., 2014). Higher weight and BMI, in turn, may contribute to the development or worsening of obesity for adults (Gutiérrez-Repiso et al., 2014) and children (Martinez et al., 2014), although findings are mixed for adults, due to other factors that could impact their weight gain, such as eating disorders, eating habits, media use, and sleep quality (Magee & Hale, 2012). Sleep quality refers to the absence or minimal prevalence of sleep disturbances (Yeh & Brown, 2014). Sleep quality may also impact sleep duration because repetitive sleep interruptions can wake people up earlier than they want to, or decrease their motivation to sleep for more than 5 hours (Gonnissen et al., 2013).
The underlying mechanisms that connect sleep duration and weight gain remain unclear because of the complexity of the relationships among them and the existence of confounding, moderating, and mediating variables (Magee & Hale, 2012). Magee and Hale (2012) reviewed studies that examined the causal pathway between short sleep and weight gain, and they noted that sleeping for five hours .or less can increase hunger due to higher leptin levels and lower ghrelin levels. Short sleep also presents more opportunities to eat, changes in thermoregulation, and greater fatigue that may also make the body store, than burn, fat (Magee & Hale, 2012). .The two main causes of obesity that sleep deprivation may stimulate or facilitate are higher caloric intake and lower energy expenditure (Magee & Hale, 2012).
