It seems self-evident to assume that the link between poor sleep and weight-gain has to do with the lack of energy and motivation to engage in physical activity, as well as the association between short sleep and our sweet-tooth cravings the next day. But contrary to our intuitions about the seemingly passive role of sleep, poor sleep engages a cascade of processes that actually set in motion pathophysiological processes that often lead to insulin resistance, diabetes, blood sugar instability, increased fat storage and other adverse metabolic effects. These processes create a snowball effect that make it ultimately impossible to sustain a healthy lifestyle despite our self-proclamations aimed at marshaling 'willpower'— or admonitions from Hollywood-style trainers on TV. You don't need a "Drill-Sergeant"— you need to understand your sleep patterns in greater detail.
Poor sleep quality, short sleep times, and common sleep disorders such as sleep apnea set in motion little tiny shots of an adrenalin-like substance through incessant bursts of nerve activity. Adrenalin may sound like a good thing when it comes to energy, but like stress itself, and like popular energy drinks, it may feel good while you're juiced up— not, however, when your brain is prevented from consolidating important stages of deep sleep. Subsequently, your body sets in motion a cascade of metabolic adjustments and appetite releasing processes that work to seriously undermine any measures you've taken to control your diet. Even when you are rigorously controlling your diet and exercising, you are effectively exchanging 'good' lean tissue for increased percentages of fat. Want to get back on track? Test for OSA.
