By nature, we are genetically programmed to eat whenever opportunity presents itself, presumably stemming from times when food was much scarcer than it is today. And although the "feast or famine" scenario is no longer as common as it used to be, our instinct for making the most of opportune encounters still exists and influences our behaviour.
What is more likely to cause overeating -- a quick bite on the run or a sit-down meal in a relaxed atmosphere? Surprisingly, it's the rushed eating event that most often seduces us to overindulge. Why? For a number of reasons, most of which we are completely unaware of, according to scientists who study our eating behavior.
Here's the thing about meal plans: they are absolutely genius -- and practically fool proof -- when adherence is strict. When one fails to plan to follow their plan, however, by say, not doing their weekly food prep or pulling into a drive-thru when hunger strikes, the results they are searching for get further and further away.
