Your body is unable to metabolise carbohydrate and fats efficiently leading to unhealthy weight gain. At the same time alcohol also diminishes your body s ability to utilize nutrients such as vitamins and minerals leading to malnutrition. When you drink alcohol excessively, your energy intake increases considerably but your body s requirement for B vitamins also increases simultaneously which if not met through adequate nutritious food intake, affects the way carbohydrates are utilised by the body leading to disturbed metabolism. Being a female it is harder for your body to metabolise alcohol. It is best avoided as you are an adolescent and you need good nutritious food for your body s proper growth. Try to de stress in a healthy way such as engaging in an activity that you enjoy be it playing games with friends, gardening or listening to good music, dancing etc. Avoid emotional eating/binge-eating which again will affect your health and weight adversely.

So steer clear of your enemies and befriend a positive outlook and a healthy lifestyle.
