While losing excess weight and keeping it off is undeniably the best way to go, anyone who has pounds to lose shouldn't let the fear of yo-yo dieting keep them from trying to shed their excess pounds.

The key to keeping weight off is maintaining good habits -- exercise and healthful eating don't go away once you hit your goal weight. It's also a good idea to step on the scale from time to time to make sure you're sticking to your goal weight. Diet Blog has some more weight maintenance tips to share.
