A crucial factor that can impact success in a weight loss journey is maintaining a sustainable and realistic caloric deficit. Fad diets or extreme cutting often lead to temporary results but are hard to maintain, resulting in yo-yo dieting. Instead, focusing on gradual changes in diet and incorporating regular exercise is essential for long-term success. Personal motivation, planning meals, and developing healthy habits also play a role in consistent weight reduction. Sustainable weight loss involves integrating healthy choices into daily life.
