Weight loss isn't easy. So when you're trying to lose those stubborn pounds, it helps to have someone you can confide in and someone you can count on to bolster your resolve when it weakens. In turn, you can do the same for your pal.

But ZoneDiet.com conducted a survey that shows there's a little distrust among diet buddies. Here are just a few of the things they uncovered:

• Two-thirds of those surveyed believe their diet buddy is lying about what they're eating.
• Over 60 percent would be unhappy if their diet buddy lost more weight than they did, but 70 percent say it would also make them unhappy if their buddy didn't lose any weight. (So we're OK if they lose some weight, but not if they beat us at our own game. Nice.)
