Dealing with perfectionism in weight loss requires a shift in mindset. Instead of striving for perfection, aim for progress. Understand that progress is not linear and setbacks are normal. Embrace the journey, not just the end goal. Focus on developing healthy habits rather than chasing a perfect number on the scale. Learn to accept imperfections and mistakes, and use them as opportunities to learn and grow. Lastly, be kind to yourself and practice self-compassion. Recognize that you are doing the best you can, and that is enough.
