help, need your advice!

My family and I have come to a place now where we are so happy and satisfied with our eating lifestyle, that we are thankful to God for showing us a better way in terms of our health. We have so much energy now, versus being tired all the time, health complains are gone, those nasty headaches that made me throw up are history, and as a bonus, we have smaller waistlines.
If you're like that, you'd know what I mean. You'd feel good all over, etc, etc. I'm sure you see friends and family not eating as healthy and are concerned about them and maybe even try to convince them that there is a better way.
What do you do when you hear from a loved one miles away who's not doing as well? What if, you're not a major influence to that person? Maybe you've been in this situation before. Hey, I could really use your advice! Or maybe you're just clever. Can I pick your brains for once and ask for a word of wisdom? I would ever be so grateful. I'll even send you a chocolate bar, vegan, that is.
