    I hope Tara wins! I think she is the BESSTEST!!

  2. blviewer says:

    Tara, you should have won. You looked awesome and Helen looked unhealthy. But everyone loves you, and you will get tons of modeling gigs!

  3. Ruth R says:

    Tara, you looked fantastic and so happy yesterday! I know that you are disappointed about not having the highest percentage of weight loss. However, remember this: you are an inspiration to everyone struggling with their weight. You never gave up. Please don’t lose that confidence that you have gained. You are a beautiful and determined young woman with your whole life ahead of you. Continue to make the most of it!

  4. Ashley says:

    You are the biggest loser to me. I know you will continue to do awesome with your goals in life and like the others on here said you will most likely get a BUNCH of modeling gigs. Your a beautiful person inside and out.
    You WON in my eyes.
    ~good luck~

  5. fridalola says:

    Good luck with maintaining the weight loss. To me what motivated you most was “beating” everyone else. You constantly said how everyone was against you, “wanted you to fail” and other sad comments that I guess kept you fighting for what you thought was your rightly deserved prize. They all fought just as hard as you. I am glad Helen won, but you absolutely won your life back and that is what is the most important thing. I believe loving yourself enough is what keeps us from becoming obese and at 23, you were heading toward a short sad hard life. Good for you that you turned it around. Now its time to take on the challenge of fighting that other Tara, that led you to that. Again, I wish you the best of luck.

    You won in my eyes.
    And like another person has said, I am sure you will get a bunch of modeling gigs, its just a matter of time before everyone see’s how beautiful you are. keep up the good work because im not lying when I say that you have made a change not only in your life but in the lives of the people who have followed your journey.
    You are the biggest loser to me!!!
    Good luck tara, your awesome

  7. AF Guy says:

    I know you are probably disappointed by not having the biggest percentage but in my mind you were the winner! I have never seen anyone dominate a competition as much as you did on this years show! You simply didn’t have anymore weight to lose. You looked very beautiful (you were always pretty), sexy, and happy last night! I really enjoyed watching you compete and beat everyone this year and it has been a very long time since I have seen anyone with your sheer willpower and focus! Best of everything in life to you always! I hope you stay active in the public eye, because you are an inspiration!

  8. Becca says:

    Tara, You were amazing, and in my eyes YOU are the Biggest Loser. I loved watching you in the show, you have an amazing personality and have so much drive. You looked so good on the finale, your a very beautiful woman, and a huge inspiration to me. Im going to miss watching you every tuesday 🙂 Love ya and stay strong girl.

  9. Greg says:

    Tara was my favorite from the beginning. She’s the biggest winner.

  10. I hate Tara says:

    you have to be kidding me…are we all watching the same show? Tara was a little [censored] cry baby. They are all ganging up on me. I wanna go home. Im gonna leave. Does anyone remember THIS Tara? And how long is it gonna be before the boob job. In all the time I have watched the show, I cant imagine anyone else who could drive Jillian to quit

  11. webgoddess says:

    Tara is so extremely inspirational. I feel completely connected to her. Out of all of the contestants on TBL over the seasons, Tara is the most like me in attitude and focus and personality. I was rooting for her from the very first episode and I saw her beauty immediately before she even begin the journey. As the weeks progressed and she kept winning challenge after challenge my admiration and respect for her continued to grow. She really is the best TBL contestant ever. I would love nothing more than to be friends with her in real life, she is the type of person I aspire to be. I really liked Laura too, and was very happy to see her overcome the injuries and look fantastic in the finale.

  12. Glo says:

    Tara, you were a joy to watch. I loved your competitiveness.
    You look great. I hope you are able to stay in shape.

  13. lapar says:

    The satisfied look on your face as you stood on that scale for the final time said it all. I want that same inner contentment. Thanks for the encouragement “emerald girl”. You are a true gem!

  14. christine says:

    Tara…you r the winner.. u r stunning! I felt sad when helen came out lookin the way she did, it was awful. I hope jillian, bob and BL address it.! U r amazing andstrong. I am so proud of u!!!!!!!!

  15. anonymous says:

    I’m so glad Tara didn’t win, she was full of herself right from day 1, she had an attitude that she was better than everyone else. If there was a show called The Biggest Whiner, she definitely would have won. Kristen deserved it so much more. Way to go Helen.

  16. sheree says:

    Tara you ROCK! She is an inspiration to everyone. As far as I am concerned she is the winner. Keep up the good work.

  17. Roxane says:

    I loved Tara! She was nice and well grounded. She didn’t get involved in anyone else’s drama. She was there to focus on losing weight and getting healthy and that is what she did. I never get into this show, but Tara made me a big fan!

  18. Not a Tara Fan says:

    this blog shows the mentality of america…a crap load of morons following a self centered cry baby who pulled the wool over their eyes and made them believe that she was a great and admirable person and a mere few that are able to see her for what she really is…god, its no wonder that george bush was president for eight years.

  19. PureInspiration says:

    It’s so funny to see how some people are so jealous of Tara, if you don’t like her keep your mouth shut why would you waste your time coming on her to type bad stuff about her if your not jealous, don’t you have something better to do? What she gonna do lose a challenge on purpose BS how stupid would that be, just cause she is a bad and tough doesn’t make her selfish and a “cry baby” i guess all of them are cry babies cause i seen everyone of them cry at least once that is so ridiculous, just because people have heart makes them a “cry baby” are you kidding me? LMFAO. She is a very strong inspirational woman anybody who can lose 155lbs period is absolutely amazing. TARA YOU ROCK!!!

  20. brandy1022 says:

    tara, if u read these ignore all the people who seemed to hate u. when reality tara is the only person on this show that did not get into any of those alliances with people, and that is what got her so far, and because she got upset in 1 episode everyone calls her a cry baby, u would be upset if everyone ganged up on u also. i liked tara from day1 and i watched every episode, tara u are an inspiration to me and to alot of people, keep up the good work. i hope to see u on the next season, as a guest host or just a guest on the show, i think that would be awesome. good luck!

    I cannot believe some of the comments on this blog. I understand that this is a place for people to sound off, but wow…for those of you who have positive things to say…you make me proud to be an American. For the rest of you…do you personally know any of these contestants? I am sure there are positive and negative things about all the contestants but you need to find some joy in your life if your screen name is directly aimed at hating any of these contestants…People go on the show to lose weight and to gain their lives back. It is a game and I don’t remember one single contestant in the history of BL (and I have NEVER missed an episode) who hasn’t had some less than positive quality. Be happy for all the players! Anyone who has lost any weight whether it be 40 pounds or 200 pounds should be proud. And on another note…What in the world does any of this have to do with a guy who used to be President? Not that it matters, but I don’t think President Bush had anything to do with the BL winners or losers. It’s like the saying goes…if you don’t have anything nice to say…then be quiet.

  22. Jane says:

    Hi Tara! I just want to congratulate you for your big accomplishment. You are just a FANTASTIC human been. I was very disappointed you did not win first place but you earn more that that you earned your life back!!! You look Amazing!!! So happy for you!!! Love you!!!

  23. she's saggy says:

    Can’t wait to see her put the water back on. Can’t wait to see her binge it all back on out of disappointment at not winning the money. Because isn’t that what matters the most? The person who loses the most weight, whether it be fat or water,and takes home the money. Not who got healthy in the head, as well as the body, and changed bad behavior patterns for good. She was a smartass to everyone else, but when she felt like she was being ganged up on, she was ready to bawl. Not CRY, like everyone else did, out of exhaustion, or frustration, or missing loved ones, but BAWL, like a bully bawls when they get what they give, and can’t take it. Like when she told Aubrey to shut her mouth when she pointed out that she was gonna bawl. What a great spirit, what a class act. It seemed it was all about winning weigh-ins and challenges for her, and not about staying healthy the next fifty years of her life. And, unfortunately, when you look at past competitors who seemed to only be in it for the money, the vast majority of them have put some, if not all of their weight back on. And the dress she wore at the finals was horrendous. Wasn’t she a model? Can’t she tell when an outfit does not flatter her figure? It made her bosom look flat and saggy. I know she must have lost weight in her breasts, so why not get a dress that would would flatter her figure. And speaking of breasts, you KNOW the implants are coming. She has shown herself to be way too insecure to leave those socks hangin’. I loved it when she had Helen go first. She was POSITIVE her only competition was Mike. The look on her face when she saw her final weight was awesome! Like someone kicked her in the gut. Nothing like a 47 year old mom beating you at the weigh-in to put you in your place.
