Being a unisex group, I'm not sure a guy would be like being part of a group called the r.o.s.e.s.
An all girls group I used to belong to on ediets was named the Foxy Ladies (also not suitible for the occasional guys that drops in)
Just a suggestion,
we could call ourselves Club 5
Club, because it's a group where we meet daily. We could say to friends and family we're going to the club, and really just go on the 'puter to check-in.
5 because there are 5 food groups we should all be eating from.
There are five groups in the Food Guide Pyramid:
1) Breads, Cereals, Grains, & Pasta
2) Meat, Fish, Poultry, Dried Beans, & Legumes
3) Milk and Milk Products
Fats, Oils, and Sweets are included on the pyramid, but there is no specific recommendation other than to use them sparingly!
I also once belonged to other diet groups called the Hooters, Angels, Sisters, Lifes Odyssey and The Mother's Dayer's also unsuitable for a Unisex group.
