Ever heard of the twilight zone diet? It's the one where you swear you're doing everything right but still can't drop a pound. Part of the problem may be that your intentions don't match your actions: Recent Cornell University research found that people tend to underestimate the calories they're eating by as much as 38 percent. And they exaggerate how much exercise they get, overestimating calorie burn by as much as 62 percent, according to a University of Texas study. Add these findings together, and you could be 100 percent stuck. 

But researchers are finding new ways to help you get back to reality. With the following strategies, you can start winning at the losing game. 

Strategy 1: Turn Every Meal (and Snack) into a Photo Shoot
Strategy 2: Beat the "Weekend Effect"
Strategy 3: Track Every Step, Measure Every Calorie
