Why you shouldnt drink alchohol...

Alcohol is empty calories. It doesn't have any nutrients, but does have a caloric value of 7 calories per gram. In just one shot (1.5oz) of 80 proof vodka there's nearly 100 calories. For those of you trying to lose fat, forget it if you are drinking. Not only will the high calorie content of alcohol have a negative effect on your total calorie intake, but it also slows down your metabolism by disrupting the Kreb's cycle. Since the Kreb's cycle isn't working correctly, fats cannot be broken down. In short, your body is trying so hard to digest and metabolize the alcohol, that fat burning stops all together.

          Alcohol consumption also hurts muscle growth. Not only due to hangovers lowering your workout intensity, but it actually lowers protein synthesis by 20%. Twenty percent! There are several 

          reasons why it does this. For one, it dehydrates your muscle cells. As many know, hydrated and even over hydrated muscles (like when you take creatine) allows for a much higher anabolic 
          environment. Because your cells aren't holding as much water, it becomes much harder to build muscle. The second reason why alcohol can severely hurt muscle growth is because it blocks       

          the absorption of many important nutrients that are key to muscle contraction, relaxation and growth including calcium, phosphorus, magnesium, iron and potassium.

        ALCOHOL LOWERS TESTOSTERONE AND INCREASES ESTROGEN! Yes, you read that right. In one particular study, men's testosterone levels were measured before and after consumption of
        alcohol.At the most intoxicated state, testosterone levels had dropped to an average of 25% lower. It was also interesting to note, that when blood alcohol levels were the highest, testosterone was
        at its lowest. Alcohol has also been shown to cause a quicker aromatization of androgens into estrogens, which would explain why heavy drinkers often get gynecomastria (bitch tits) over a period

        of time.For those of you taking andro (and I'm sure you already know my views on andro) I would absolutely avoid alcohol since you already are in risk for gynecomastia with the high androgen 

        levels in your blood. By drinking, you are further putting yourself in risk for aromatization. We should also note, that in a study done with rats, alcohol reduced Insulin like Grown Hormone(IGF-1) by 
        up to 42%. That's a huge drop in IGF-1.One thing I found unusual due to the drop in testosterone while drinking is that most guys get really horny. Beyond getting beer goggles, why is it that            

        drinking makes you horny? What I found out is that because alcohol lowers testosterone levels so significantly, the body is struggling to bring them back up by releasing LH, in very large quantities.
        What's also interesting to note is that LH is just as responsible for arousal as testosterone. Unfortunately alcohol reduces testosterone levels at the Leydig cell, not the pituitary, so the LH is 
        ineffective in raising testosterone levels.
