The truth about alcohol, fat loss and muscle growth
Summary
"* Moderate alcohol consumption is assocoiated with an abundance of health benefits. The long-term effect on insulin sensitivity and body weight (via insulin or decreased appetite) may be of particular interest to us.
* The thermic effect of alcohol is high and the real caloric value is not 7.1 kcal: it's ~5.6 kcal. However, it's still easy to overconsume calories by drinking. Calorie for calorie, the short-term effect of alcohol on satiety is low. Adding to this, intoxication may also encourage overeating by disinhibition of dietary restraint.
* The negative effects of alcohol on testosterone and recovery has been grossly exaggerated by the fitness mainstream. Excluding very high acute alcohol consumption, or prolonged and daily consumption, the effect is non-significant and unlikely to affect muscle gains or training adaptations negatively.
* The effect of alcohol on muscle protein synthesis is unknown in normal human subjects. It is not unlikely to assume that a negative effect exists, but it is very unlikely that it is of such a profound magnitude that some people would have you believe.
* Alcohol is converted to acetate by the liver. The oxidation of acetate takes precedence over other nutrients and is oxidized to carbon dioxide and water. However, despite being a potent inhibitor of lipolysis, alcohol/acetate alonecannot cause fat gain by itself. It's all the junk people eat in conjunction with alcohol intake that causes fat gain."
