"When you take in more calories than you burn, the excess calories are stored as fat. Where your body stores that fat is determined in part by your age, sex, and hormones.
Alcohol is metabolized differently than other foods and beverages. Under normal conditions, your body gets its energy from the calories in carbohydrates, fats and proteins, which are slowly digested and absorbed within the gastrointestinal system.
However, this digestive process changes when alcohol is present. When you drink alcohol, it gets immediate attention (because it is viewed by the body as a toxin) and needs no digestion.
Generally speaking, alcohol intake is associated with having a bigger waist, because when you drink alcohol, the liver burns alcohol instead of fat. Alcohol also suppresses testosterone production, the primary metabolic hormone, this can last up to 24 hours following consumption. So not only does alcohol delay your liver’s ability to break down fat, it also obstructs your body’s access to the hormones it needs to help you break down fat.
When the body is focused on processing alcohol, it is not able to properly break down foods containing carbohydrates and fat. Therefore, these calories are converted into body fat and are carried away for permanent storage on your body. Even though alcohol contains calories, alcohol doesn’t satisfy us in the same way that food does. This means we don’t end up consuming fewer food calories to compensate for those we’ve drank.
In fact, alcohol can make us want to eat more! Alcohol increases your appetite by suppressing leptin, the hormone which normally tells your brain to stop eating and negatively effects many other brain chemicals that are involved in appetite suppression. It can also makes us lose our inhibitions, making the decision to grab a slice of pizza or a greasy kebab all the more easy. Our healthy food choices become less important to us!
Another important fact to remember is alcohol is a diuretic, meaning that it causes water loss and dehydration. Along with this water loss, you lose important minerals, such as magnesium, potassium, calcium and zinc. These minerals are vital to the maintenance of fluid balance, chemical reactions, and muscle contraction and relaxation.
Alcohol affects your body in other negative ways, it may help induce sleep, but the sleep you get isn’t very deep. You get less rest, which can trigger you to eat more calories the next day.
So there we have it. As you all know I am not one to shy away from a drink but I do find this very interesting and fully understand now the reason behind not just the additional calorie intake but the crap feeling you have for days afterwards and the affects on your body. Something to keep in mind next time your hitting the town or enjoying a cheeky few at home.
