When it comes to losing weight, everyone's in search of a magic bullet. But don't fall for the hype. Unfortunately, there's no short-term fix for long lasting weight loss.

So learn to identify these six red flags:

1. Diets that promote or promise drastic weight loss.

When you start a diet, you can potentially drop a lot of weight during the first two weeks (some of which will be water weight). However, if you lose more than two pounds per week in the weeks that follow, you run the risk of losing "muscle mass," and your metabolism will slow down in response. That's why true health experts advocate losing weight slowly and gradually - so you melt away fat while sparing precious muscle.

2. Diets that claim to work because of special supplements, creams, or potions - no diet or exercise required!

Or diets that make you buy mega supplements in order to follow the program. If it sounds too good to be true, it is!

3. Diets that differ entirely from the way you currently eat (or like to eat).

If a plan is incompatible with your lifestyle, chances are slim you'll stick with it.

4. Diets that are less than 1,000 calories.

Too difficult to sustain and can often leave you cranky, irritable, and with a bad headache. Not to mention hungry and lethargic.

5. Diets that claim they are effortless.

There's no such animal. Losing weight takes focus and effort. Period.

6. Diets that cut out entire food groups, or focus on only a few foods.

Not realistic for the long haul; the sign of a plan you're soon to go off.
