The Science Behind the Relationship between Nutrition, Performance in the gym and the Quality of Your Sleep. Did you know that not getting enough sleep can increase your appetite leading to additional calorie intake throughout the day? Studies have recently shown that individuals who sleep less tend to possess higher body mass index (BMI). The mechanism underlying this effect may be the balance between hormones that boost and those that suppress hunger. Spiegel et al. (1995) found that subjects who slept 5 h per night possessed 15% more ghrelin (appetite stimulating) and 15% less leptin (tells you your full) compared with those who slept 8 h.Sleep deprivation has been hypothesized to contribute to obesity by decreasing leptin, increasing ghrelin and reducing insulin sensitivity (helps store energy in muscles, but becomes desensitized with less sleep, reducing energy storage). Sleep deprivation has also been associated with elevated resting cortisol levels. Cortisol activates lipoprotein lipase (LPL) which has been shown to encourage fat storage.Thus, sleep duration may be an important regulator of body weight and metabolism and may indirectly influence exercise-induced weight loss.
