I've been pretty good so far – my biggest choice to change was to prepare a lunch every day and not just rely on going out all the time. Not only a calorie-saver, but a money-saver, too. Good ol' portion control, healthier choices, etc. Actually felt really good, too. Today we have a guest coming in for an office lunch so I only brought snacks for the day (yogurt, nuts, etc) and I'll try to make a smart choice on the lunch entrée. It does make a difference; while it's obviously way too soon to be having an effect overall, I immediately notice an absence of bloat and disgustingness, so that's a plus.
I've made this change before; sadly, when my daghter was born I allowed myself to fall off the wagon COMPLETELY. Not even an excuse, just an explanation; I should have been able to stay on the regiment, but I didn't. So now, 2 years later, I'm finally really trying to get back to it.
