Hi, Kathleen: Good to read your posting. I'm 11 days in and feeling great. I'm 48 -- which is close enough to 60, I think. Many of my friends are in their 60's. Biologically, I don't think age makes a huge difference. Good on you for losing 100 lbs -- unimaginable to me! I'm here to lose 10 and start a good weight-lifting programme.
I came to this programme but have been eating 'clean' for most of my life -- so this is not a big leap for me. So far, no hardships, no headaches. I have been off sugar since December 2011 -- so, again, no withdrawal symptoms.
Some things that I miss are: cheese. I drink red wine.
Look forward to hearing from you.
