What do most people do when they want to lose weight? They go on a diet.

And for the vast majority, it won't be the first diet they've been on. And the reason they are planning to start another diet? Because they believe diets work.

But if that's true, why would people ever need to embark on more than one? Chantal Cooke of Beauty4Media shares how we should really think about losing weight.

Diets require food intake to be constantly monitored. "Points, calories, red and green days, fat grams, etc. So guess what? You end up thinking about food all the time," Henson said.

And that's another problem with diets. "They generally concentrate on reducing food intake, either generally or for certain food groups, so you're constantly feeling deprived," the author said.
