low glycemic diet vs MFP

I've been debating whether the low glycemic diet would be better for me or shouId
I continue my program with MFP. I struggle with staying on the diet and always think
The grass is greener on the otherside. But in the words of my wise 85 year old mother
Is the grass seems greener over on the other side but once you get there it's really not.

Please send me some comments regarding staying fast to the MFP program.

Have a great day.

Jimmy.
