Alcohol and Weight Gain - What's the Confusion Really

How Is Alcohol Processed In The Body?

To gain an understanding of why alcohol affects us the way it does, it is important to known how it is processed in the body.

After consuming the first alcoholic drink, 25% of this alcohol is absorbed straight from the stomach into the bloodstream, with the remainder taken in through the small bowel. Alcohol is generally absorbed fairly rapidly, but its absorption can be quickened depending on several factors:

1.      The amount of food in the stomach (a fuller stomach slows the rate of absorption).

2.    Whether the drink is carbonated (champagne is absorbed more quickly than non-sparkling drinks).

3.    Alcohol concentration of the drink (higher alcohol drinks are absorbed faster).

Around 98% of alcohol that is consumed is processed in the liver, with the other two to ten percent being expelled through urine, breathing, or sweat. The amount of alcohol in a standard drink will take around 10 hours for the average person to process, which means the more that is consumed at any one point, the greater the rise in blood alcohol content. When the liver processes alcohol, it does so in one of two ways.

1. Alcohol Supplies Almost Twice As Many Calories As Protein And Carbs

At seven calories per gram, alcohol supplies almost twice as many as protein and carbohydrates. In fact, alcohol has only two fewer calories than fat, which has nine per gram. It must also be remembered that the calories in alcohol lack the nutrients beneficial for a healthy metabolism and will therefore hasten fat storage.

The calories found in the average alcoholic drink are quite concentrated compared to many foods, and this actually causes one to inadvertently take in many more calories than would otherwise be consumed. Alcohol is quite deceptive in that it passes through the system rapidly, often before the drinker is aware of the number of drinks they have had.

Alcoholic drinks also contain calories from other sources, which add to overall caloric intake. Certain cocktails, for example, contain fats. Wine and beer both have high carbohydrate content. Although the affects these various calorie types have on the body are different—carbohydrates release insulin, which can hasten fat storage, while fats will be stored directly in the fat cells—the overall result is added body fat.

Beer contains more carbohydrates (although many of the "Lite" beers have a carb content similar to a glass of wine) and less alcohol than wine, but is seen as being more fattening, due to its higher energy content.

2. Alcohol Loosens The Inhibitions

While drinking, people usually will not stop to consider the impact alcohol is having on their bodies; such is alcohol's affect on loosening the inhibitions. The result of this relaxed thinking could mean more calories consumed and extra body fat gains. Those drinking might also eat more of the wrong kinds of food, without thinking of the consequences.

Alcohol tends to have an appetite stimulating effect as it provides little in the way of nutrition, leaving a craving for other foods at the time of consumption. Add this to the fact that fatty and salty foods tend to accompany most occasions featuring alcohol (as well as alcohol actually stimulating one's appetite for these kinds of foods), and the general loosening of resolve that goes with an inebriated mindset, and you have a recipe for excess fat gain. Alcohol has also been shown to affect motivation, making a healthy diet harder to stay on while it is being used.

3. Alcohol Can Damage The Stomach, Kidneys, And Liver

Given alcohol is a by-product of yeast digestion; it can have an irritating effect on the lining of the stomach and gradually weaken the kidneys and liver, leading to serious health problems—even death in certain instances. Any weakening of the stomach will lessen the rate and efficiency at which food is digested, which ultimately interferes with a healthy metabolism and the weight loss process.

The liver—which processes toxins and breaks down fats for fuel—is crucial when it comes to maintaining a healthy body composition. Alcohol is at its most destructive during the liver's detoxification process.

4. Alcohol Lowers Testosterone

Testosterone, which has a powerful fat loss effect, is reduced whenever alcohol is consumed, thus halting its full potential as a fat burner. Also, testosterone as an anabolic hormone, contributes to gains in lean muscle mass. Lowered testosterone means fewer muscle gains, and less muscle means a lowered metabolic rate.

A lower metabolic rate will make the job of losing fat all the more harder. This is what governs the way we use energy. Those with a higher metabolic rate will burn more calories at rest. By interfering with testosterone production, alcohol indirectly causes the body to lower its metabolic rate (and thus the rate at which it uses energy) and directly prohibits testosterone from exerting its powerful fat-burning effects.
