Fattening carb-units that you consume from munching on junk food while languidly
yacking on the telephone, and thus said overly-rich-nutrients are more effective at packing on the pounds, just as they are if you
chomp on chips and beer while sedentarily watching TV on the couch instead of exercising.
If you love
gabbing with your buds
on the horn for extended periods, a simple way to avoid the effects of callories is to only chow down on celery and
carrot sticks (unsalted peanut butter can help make these "dull" foods more palatable) during these intervals, and save the tastier starchy/salty/sugary snacks for times when you're more active.
