New research found by Professor Francesco Cappuccio showed that a lack of sleep is associated with obesity. This is the funniest thing i've heard all year! What i think and my colleagues is that, because your awake till late you get bored and eat more. That doesn't mean you'll be obese, well thats my opinion. More awake=More appetite. Prof Cappuccio's research shows that the chemicals in the human body produces Ghrelin which is one of the substances that make you hungry. Less Leptin is produced which is one of the substances that make you less hungry. This guy intends on findin out more bogus sleep related investigations that are accosiated with diabetes and hypertension. This research reviewed is on over 28,000 children and 15,000 adults.
