There are many reasons you might want to lose weight, and research suggests that these factors can change throughout your weight loss journey (14).
That being said, research has found that physical appearance and self-esteem are two of the biggest driving factors for wanting to lose weight (14, 15).
One small study also found that acknowledgment from a healthcare professional and comfort speaking with a doctor played a key role in participants' desire to lose weight (16).
Other motivating factors supported by research include health-related concerns, illnesses, societal pressure, and body dissatisfaction (17).
