This is a very interesting topic! I truly believe that it has to be a mind set that you are in. I talked with my neighbour extensively about this very thing. She lost 160 pounds on WW over the last 18 months. But what she relayed to me over and over again was that she had gotten to the point of being so low that there was no place further to fall. She said she remembered sitting on her floor and crying one day and realizing that she couldn't live like that any longer. On that day, she made a decision to change her life and never waivered after that. She was committed to losing weight and joined WW. She started mall walking. At first she said she could only walk for about 15 minutes and now she's up to power walking for an hour and a half every day! It will be interesting to hear from people on both sides here, those who have successfully lost and those who are struggling. ( I'm a struggler BTW)
