Learning to eat less of the high-calorie foods you love isn’t always easy. What can make it even harder: having to stare down those fattening foods at your very own dinner table.

From the spouse who brings you a huge box of chocolates on Valentine’s Day to the mother-in-law who plies you with home-baked goodies to the skinny friend who invites you to uber-fattening lunch dates, the result is much the same. While their intentions may be all good, experts say the results can be all bad for the dieter trying to stick to a healthy eating plan.
