Criticism has its way with success. This is true of weight-loss success as well. Before you know it, you can blow it. Goal weight is then up for grabs. Nothing's sure once criticism gets to you.
Two sources of criticism we all have to deal with is the criticism of others and our own critical voice. But we have a third that's as powerful, feeling critical of others and being critical of others. All criticism involves strong emotional reactions that eat at you. And it is the sting of these strong emotional reactions that have their way with your weight-loss success.
Being able to handle criticism in new and better ways is what will help you keep dieting, keep losing weight, and keep off the weight you've lost. See if you can transform criticism received or criticism given into a more positive communication, one that will be better for all involved.
