Check your weight-loss readiness
Weight loss requires commitment. Ask yourself the following questions to help you determine your readiness: 1. Am I willing to change my eating and activity habits? 2. Do I have the time to spend on making changes? 3. Or am I too distracted by stress and other pressures? Talk to your doctor if you need help addressing stressors or emotions that seem like obstacles to your readiness.
