If that's the case Hachna, i need to love myself more!
There will always be people who construe food as symbolic of love. This is a deep seated core belief that some have. Core beliefs are rarely changing over a lifetime without significant professional help. Therefore, the likelihood of maintaining the new feeding behaviour in such a person, is likely to relapse back to original behaviour, as 'I cant, its not fair, she loves her food' is his/her TRUTH, not "im being cruel to be kind".
so a bit of education, a bit of community opportunity to get active, dog parks/beaches available, wil entice the ones that are willing. Those that arent, wont be changing anyhow.
But before i go jumping up n down about dogs, i wanna tackle obese parents, with their obese kids first. Sickens me more than the "i used to be a labrador, now im a single bed with legs at the corners"
