Summary of Alcohol

Primary information, health benefits, side effects, usage, and other important details

Alcohol, otherwise known as Drinking alcohol or ethanol, is the main ingredient in a wide range of social drinks and the reason for the differentiation between 'Alcoholic' and 'Non-alcoholic' drinks.

It is a neuroactive chemical that is able to change one's perception, and has a unique metabolic pattern relative to other sources of calories (the macronutrients; carbohydrates, proteins, and dietary fats). It contributes 7 calories per gram energy-wise, but this does not always correlate well with bodyweight like the other macronutrients do.

How to Take

Recommended dosage, active amounts, other details

Abstinence from drinking is defined as having no ethanol intake whatsoever.

"Moderate" drinking in the literature is dependent on gender and not ultimately defined, but an upper limit can be placed at 9 units per week for women and 12-14 units a week for men, with no single event exceeding 4 units.

A unit is typically 12 oz (355 mL) of 5% beer, 5 oz (150 mL) 12.5% wine, or 1.5 oz (45 mL) of drinks with a higher (40%) alcohol content.

Unlocked for Examine members

The Human Effect Matrix summarizes human studies to tell you what effects Alcohol has on your body, how much evidence there is, and how strong these effects are.

Full details are available to Examine members.
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only

There appears to be a time-dependent influence on testosterone, with acute doses of alcohol increasing testosterone secondary to creating energy influx in the liver (small enough of an increase to be 'somewhat' effective but may contribute to libido) whereas abuse is known to reduce testosterone levels more notably. The acute increase in testosterone is thought to be related to spikes in libido
