Alcohol - Empty Kilojoules!
Alcohol is often referred to as ‘empty kilojoules’, because it has plenty of kilojoules, yet no nutritional benefit. i.e. Your body doesn't get anything useful out of it. It may also lead to impaired judgement, and excessive eating, thus significantly increasing the energy intake and weight gain.
Increased alcohol consumption can also lead to high blood pressure, consequently increasing the risk of heart disease and stroke due to the increase in triglycerides.
