The researchers found that when glucose was restored, subjects' self-control behaviours - such as controlling attention, regulating emotions, quitting smoking, coping with stress, resisting impulsivity, and refraining from criminal and aggressive behaviour - was improved. Then, ever wondered why you lose self-control after a couple of drinks? It's because alcohol reduces glucose throughout the brain and body, thereby impairing self-control. The glucose-self-control theory could also explain why many ex-smokers turn to sweets when they quit. 0 More: Daily Dose: 'We could see her lungs through her skin' Health-in-Motion advertisement Other news Medical This man has been injecting snake venom for 30 years – and this is what happened Medical Adele singing about ‘cheesy butter cups’?
