I don't see anything about this in the book so I figured maybe someone on here found the answer somewhere else or it was answered on this board previously.My training schedule is M-F meaning typically my Saturday should be an off day with very low carbs. I had things going on Saturday so I decided to throw an impromptu workout in there, in the morning. Waited until 6pm before I started drinking, almost all of the alcohol I consumed was tequila or vodka. Ate carbs at night with the alcohol either in mixers or food.It was one day of drinking and I don't typically drink so I'm not too worried about that. However, the next day I felt a little crappy so around noon or so I had some pancakes (tried to just eat my huge omelette but really needed some absorption for the alcohol) then a few hours later had a little more carb covered food.I'm sure I'm just over thinking this and worried for nothing, but one day of carbs before your evening meal isn't going to completely undo the entire prep phase and diet during the week right? Every other day of the week and normal weekends I stick to the diet. I think the only reason I'm even worried is that I don't see anything in the book about screwing up once in a while. I do see something about derailing for a whole week then needing to go back onto the prep phase...but again, nothing about just one day.Has anyone read anything previously about having a party night then carbs the next day to get rid of a hangover in relation to the efficacy of this diet?

See how it goes, and don't let it happen again.  🙂The rules are to back-load after sundown / after training.  if you repeat the mistake or if your progress stalls after this error, you will have to re-prep.Also, I know you said you don't drink that often, but I'd cut it entirely.  People tend to stall when they introduce alcohol.  Some may be able to get away with it, but most don't seem to.This is not to mention alcohol's ill effects on fat loss, protein synthesis and hormone levels.Cory

Yeah, there have been times where I've had some carbs during the day (very infrequently) and as long as you get back on the horse the next day and are sticking with ULC you should be fine. If you have a few days in a row of carbs during the day you may want to run a mini prep phase again

I agree with cory on this one. I would not worry too much about it, especially if it doesn't happen often. I really like this article from berkhan about drinking and fat loss, and have used these strategies in the past. Alcohol's effects on hormones are negligible if not drinking consistently. http://www.leangains.com/2010/07/truth-about-alcohol-fat-loss-and-muscle.html

It isn't just the hormonal effects.  I've read articles based on studies where it blunts protein synthesis for up to 4 hours... and it didn't require much alcohol, either.Cory

Can I see said articles? this was written in 2010 and states "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."Also this: "What about protein synthesis? Strangely enough, the acute effects of alcohol on muscle protein synthesis in normal human subjects are non-existent in the scientific litterature. It has only been studied in chronic alcoholics, which have reduced rates of muscle protein synthesis. Chronic alcoholic myopathy, which causes muscle loss, is one unfortunate side-effect of alcohol abuse. However, this study showed that alcoholics without myopathy had lower body fat percentage and the same amount of lean mass as non-drinkers. So much for the argument that alcohol makes all your muscles fall off."

I'd have to look them up, I remember reading this in Iron Man, M&F and MuscleMag at one time or another.  In fact, a recent MuscleMag did a huge write-up on alcohol and it's effects (last month's issue, I believe).This is from a quick Google search (@ Live Strong):"According to a 2001 report published in the “International Journal of Sport Nutrition and Exercise Metabolism,” protein metabolism and synthesis occurs for 24 to 48 hours after a workout. So, drinking alcohol within that time frame can potentially hinder your body’s ability to build muscle to its maximum ability."International Journal of Sport Nutrition and Exercise Metabolism”; Exercise, Protein Metabolism, and Muscle Growth; Tipton, K.D. and Wolfe, R.R.; March 2001I'd have to dig up those magazines, and see what their references were.  Most of them, esp. Iron Man, ALWAYS cite their references.  M&F is pretty good about this, too.  They were all from the past 3-4 years.Granted, a lot of what I've read discusses the effects of "heavy" alcohol consumption... but, generally, that is the kind of drinking that goes on at parties.  In fact, the bulk of (young) people, from my own observation, get tanked Thursdays, Fridays AND Saturdays EACH week.  People don't seem to stop @ 1 beer, esp. in social scenarios... and there is a certain stigma attached to drinking alone.CoryEDIT:  This all said, there are people who come on here for advice, b/c of a stall.  They weren't always binge drinking, some just had a glass or two during a CN or back-load. Clearly, it doesn't take much with some people.  Why risk it at all for empty calories, and health benefits that could be obtained from a good multi + resveratrol?
