Sometimes losing weight can mean losing your best friend.
Losing weight can increase self-esteem, energy level, sex life, and creates a new outlook on life. Mom of three Wendy Wagler, for example, lost 62 lbs and gained a new career and a much better sex life with her husband. But what about the ugly side of weight loss -- what if in the process of getting thinner, you begin to lose important relationships? Losing weight can create jealous friends, insecure spouses, competitive family members.
Melanie Slinger, 42, said going from a size 26 to a 10 "destroyed her life, and was the most costly diet in the world. I lost my job, my marriage and my kids." Losing the weight caused her to change -- her newfound "confidence" led her to increase her shopping and partying. The relationship she once built with her husband suddenly was not good enough anymore. As a result, she lost her whole world: "I regretted losing the weight. To this day, I think my marriage would have lasted if I had stayed big." Tyra talks to friends and family of the newly skinny, today, on "Tyra."
