So last night I went and saw Hangover 2. And if you’re into that kind of humour you may find this one funny. But be warned. It’s not for everyone.
But after the show was over my mind drifted back to training.
And I started thinking about the effects of alcohol on training. So I did a bit of a review of the literature on some recent studies related to alcohol consumption and exercise.
Here’s what I found.
Study #1 – Men don’t increase vegetables or decrease alcohol during weight loss management
This study included 65 men in Australia to see what kinds of changes, both positive and negative, they made with respect to their nutrition. While the men were able to reduce calories, fat intake and portion size they were not able to change their alcohol consumption or fiber intake.
Take home message: Know where your weak links are men and address them first.
ps…the lead author of this study sounds like a pretty cool guy
Men participating in a weight-loss intervention are able to implement key dietary messages, but not those relating to vegetables or alcohol: the Self-Help, Exercise and Diet using Internet Technology (SHED-IT) study.

Study #2 – Beer belly…Scientific evidence or common belief?
This study comes to us from Germany (they have beer over there?) and looked at whether beer consumption had an impact on waist circumference (WC). A interesting finding was that there was a correlation for increased WC in male beer drinkers but not in women. And while decreasing beer consumption allowed for a lower WC this wasn’t found to be statiscally significant.
Take home message: Women will put the extra calories from beer on areas other than the belly.

- Study #3 – Drinking frequency related to waist circumference
This study comes to us from Denmark where they looked at whether the frequency of drinking had any effect on WC. One thing I found interesting from this study was the different correlation for men and women. Whereas for women drinking frequency was inversely related to changes in WC, there was no association in men.
Take home message: We put on our calories in different places. More frequent drinking, even in without binging, could result in increased WC.
