I just started the eDiets Mediterranean diet this week and used their meal planner and shopping list. It was really fast and they offered a lot of variety. I liked that if you didn't like what they chose, you could click to change to another meal until you were happy with your overall plan. What I did notice was that it could be easy to get carried away with the variety and end up spending a lot more on your food than necessary. For example, one day I was scheduled to have a sandwich, but I would have had to buy a whole loaf of bread just for two slices of bread all week. If you are feeding a family, it may not matter since someone else will probably eat the rest of the loaf. But I'm just one person, and I hate wasting food. So you'll need to pay attention to details like that when creating your menu. I ended up choosing the same breakfast for every day, so that I wouldn't have to buy a lot of different foods. One package of English muffins and the toppings was enough.
Overall, I liked the convenience of having a menu generated for me, based on my personal preferences. They also came up with ideas that I might not have thought about. The recipes are simple, and they serve one person. So far everything has tasted good.
