Saw this article in The Age this morning titled: "Are you a drunkorexic? The dangers of dieting to drink".
The article discusses the dangers what some people put themselves through - skip a meal to keep the calories for alcohol instead. The issue with this is that people open themselves up to alcohol-related disease or injury and also miss out on all the goodies (proteins, carbs, nutrients, vitamins) that comes with eating a proper meal.
I don't do this, I don't condone it, but I must say that I am guilty of saving my snack calories so that I can have a sneaky something something (Arnott's Full 'O Fruit, Oreos, Ice Cream etc) as a snack after dinner. However, I have been starting to wonder how this will affect eating habits once you move off a plan like the 12wbt. For me, and I'm making an assumption that this would be the same for most folks, it's about doing the plan and creating new lifestyle habits to sustain for the years to come. Things like portion control and eating good "clean" food. I don't starve myself during the day so that I can eat a bunch of snack/junk foods after dinner but I do try to keep the snacking to a minimum. And at the end of the day, if I come under 1200 calories, I top it up with sweet/salty junk food "goodness".
As a result, I do wonder about developing the habit of always having a snack after dinner. It seems harmless enough if it's only a small treat, and perhaps a good thing in helping one keep on track during the week and not having an "unscheduled blowout" (by that I mean a treat meal other than the one specified on the Saturday after you've done a long workout). I guess it's a matter of keeping the serving sizes to a small snack serve and being disciplined (!!) enough to say no to more food.
