Everyone knows superman has a weakness... but did you know that every diet has a weakness too? Perhaps some of you have been battling that one food (or perhaps food group) that really is more than just food, but some kind of evil arch nemesis. I know I have a few lurking in the shadows. Namely Pizza, Coffee, and Rum&Cokes.
So what should you do with these perpetrators that destroy your good deeds and leave you feeling miserable/guilty afterwords? It'd be a little too easy for me to just say "Avoid them" and it'd be too complicated if I try to explain the feel good chemicals in your brain that you associate with these foods.
The best thing to do is identify them. Knowing your weaknesses will absolutely help you minimize any collateral damage these badins will do to you. For me, it's best to stay away from Friday Lunches that are to Domino's Pizza or John's Pizza and Wings. If that means a couple fridays per month I'm bagging my lunch - okay. Does it mean I might have to sit at my office and eat, sometimes yes. As for coffee... my best defense against this evil foe is to get a good night's sleep and be well rested the next day as to not require that morning cup'o'joe. And as for alcohol...try to remember that the best feel good drug is having a good time - and having a good time does not mean having 3 drinks first.
Perhaps you have your own arch rival in your diet plan - your best bet is to identify it immediately and figure out your best approach to dealing with it, because sooner or later - if you don't stay on your toes - the bad guy might win!
