I think the thing I like best about SMART is that it is smart. No one program is proven to work and lumping all of those who struggle into one blanket of inherently this or that is just plain crap. SMART tells you to find what fits. That is what is proven to help one succeed. It is an individual approach with a bit of support. That is freaking fabulous...
One size does not fit all and it does not necessarily work if ya work it!
Hugs to all!
