I have a friend who lost a whole lot of weight by subscribing to a plan that actually provides the food. This was years ago and I don't know if there is still one that will do the same thing.
Her plan gave her frozen meals. All she had to do was cook them. She had a sheet that told her which food was for which meal.
I have a friend now who subscribed to a plan that sent packaged meals to her but she would ended up picking and choosing and adding her own food and she didn't succeed. I can't think of the plan name right now.
I think I've seen Weight Watchers books that provided menu's.
My daughter uses WW points system. She bought a scale that helps her with portion sizes that also gives points info to her. She's having success in spite of not following it religiously.
And I think that Jenny Craig also provides menus but I'm not sure.
