OhMom's DM here. We did some zoning and my DH lost lots and he still likes this diet. Me, I was to (well lazy would be the word, just doesn't look so good in print) to figure the blocks, etc. DH would just tell me over and over and I could see his exasperation. Well, anyway, we did okay, I lost the usual 5 to his 15 and then we always seem to be doing so well and then we go on a vacation and then it is hard to get it started again.
I think that it is healthy and we have some very good recipes that were always tasty. DH goes to a site - will send to you. What is happening now, is that he zones, I count WW's points, it is very easy to have the same food and make it work. I let him pick what's for dinner and I just count my points and eat,
very well, as a matter of fact. I count my own points too, which I am sure makes DH very happy, tho most times I say - wait I have to see how many points that is - before I commit to eating whatever.
someone I work with (guy) lost 20 lbs in a month on zone but he has put it back on now. Had a "honey" in his life at the time and when she departed so did the diet (my thoughts anyway) but anyway it worked good for him too when he was committed.
Good luck and whatever works for you is what you gotta go with.
I am so excited about WW's points it has just clicked for me but if Zoning works - go for it!
