Cornell University professor Brian Wansink has made a career of studying people's real eating habits, and he wrote an eye-opening book called "Mindless Eating."
Wansink says a few simple tips can help you lose weight. One that worked for him was simply using a smaller dinner plate to make portions look bigger, which can help people avoid overeat at mealtime.
In his studies, Wansink also found that snackers who had to walk six feet to the candy dish ate less than half as much as those who kept the dish in plain sight on their desk.
If eating meals at your desk or in the car causes you problems, brown bag it from home or only eat when the car is in park, Wansink says.
Some other tips from Wansink:
Keep tempting foods out of sight.
Set your fork down between bites.
Ask the waiter not to bring bread.
Alternate water every other drink.
