Alcohol Effects on Fitness – Bad For Your Gains?

Oh, alcohol, why must you be so cruel? You
make me stumble around, scream out loud for no reason, pee 10 times in an hour, and perform
dares that I wouldn’t even dare to think about it when I’m sober. But at least you don’t
take away my gainz. Or… do you? How does alcohol affect your fitness gains?
Many of us have at least the “occasional” drinking nights and sometimes the rare “extreme”
drinking nights, but we hardly think about how it might affect us fitness-wise. One way
drinking affects us physiologically is by dehydration. Since alcohol is a diuretic,
the more you drink, the more you urinate, the more you’re dehydrated. In worse case
scenarios, excessive drinking can lead to severe dehydration and electrolyte imbalance.
Pair this with increased levels of a toxin known as acetaldehyde from drinking, you’re
ripe with the recipe for a hangover. Not so fun fact, acetaldehyde is also classified
as a Group 1 carcinogen, the same group as tobacco, asbestos, aaaand processed meat.
And it’s also the reason why many East Asian ethnicities have alcohol flush reactions,
aka “Asian Glow,” due to a mutation of the enzyme in charge of breaking down this toxin.
Of course, with dehydration and a hangover, you’ll feel increases in fatigue, sluggishness,
confusion, and your chances of going to the gym plummets to a near zero. And if it needs
to be spelled out, no gym equals no gainz. In fact, your gainz might already be affected
even if you don’t exercise. Studies show that low alcohol consumption, about 40 grams or
so, or 1 drink, has really no effect on the muscle growth promoting hormone testosterone.
However, that starts changing as you continue to drink more. 10 to 16 hours after consuming
3 drinks, shown to reduce testosterone levels in your body by 23%. This drop does not come
back to normal levels until 36 hours later. That’s a whole 1 and a half day you’re spending
with subpar muscle protein synthesis, and the studies also show that the worse your
hangovers feel, the lower your testosterone drops. And even worse, alcohol has been connected
to decreasing leucine oxidation, which is also important for building muscle.
Oh, and it doesn’t stop there for your hormones. Moderate amounts of alcohol has shown to also
inhibit the hormone Leptin, which is responsible for making you feel full. If you’re trying
to lose weight, good luck battling those cravings for nachos after a long night of drinking.
Speaking of losing weight or even just losing bodyfat, alcohol will also affect how your
body uses energy. Typically your body uses glucose and fat as energy through the glycolytic
and oxidative pathway. But once you introduce alcohol, your body quickly shifts its focus
from glucose and fat to breaking down alcohol for energy instead. Alcohol itself contains
roughly 7 calories per gram, which your body breaks down into acetaldehyde and then into
acetic acid and then finally a useable energy source known acetyl CoA. While this process
takes place, your body won’t be utilizing any other energy sources in your body, which
means all the calories you consume while intoxicated will be converted into stored fat and any
chances of burning fat for the duration is not going to happen.
And most of all, alcohol lowers your quality of sleep. After a night of drinking, studies
show that when you go to bed, you do in fact fall asleep quicker and into deeper sleep,
but it’s quickly disrupted and REM sleep, the deepest of all the sleep stages, is overall
reduced. When you’re asleep, much of the mechanisms for muscle synthesis and recovery takes place.
Disrupt that, and you disrupt your muscle growth.
So if you have a fitness goal that you’re desperately trying to reach, alcohol consumption
is perhaps one of your worst enemies. But if you do choose to drink, drink moderately
and choose healthier, low calorie choices. Come check out this previous video that might
