I am a relatively healthy eater. I exercise quiet frequently 4+x a week and I’m at an OK weight. I’ve always had trouble losing that last 510 pounds and keeping it off.

Many people tend to have this problem.  The important thing is to keep up the healthy eating and exercise and not to get discouraged.  Once you find the right equation for your body those last pounds should come off and stay off.

For starters, make sure you are doing a healthy mix of both cardio training and strength training.
