Also, avoid mindless eating to ensure you’re not consuming more calories than you realize.

10. Lack of Support

Having a support system can significantly impact your weight loss journey. 
Surround yourself with supportive friends, and family, or join a community or weight loss group. This will help you to share experiences, receive encouragement, and stay motivated.
