Not really. Also, frozen vegetables aren't very healthy for you; nutrients are lost in the freezing process. They work well enough for starchy veggies, but these are also the ones that make you fat.
Oh well, I hate driving enough that most of the US is permanently off limits. Freezing does destroy some nutrients but generally a lot less than aging does. Picked from your garden beats frozen but frozen generally beats store bought fresh vegetables. Point on the limited selection but getting fat on a vegetarian diet is not easy unless you eat a crapton of stuff starchier than what you get in frozen veg. Potatoes, rice, pasta.
It depends where you buy and what you buy. The poor in developing countries, ironically, get lots of vegetables and can be pretty fit (compared to ours at least). People don't really get fat because they eat too much meat (they can, just not common); its more the sugary and starchy processed foods that do it...and those sell like crack in the developed world.
Of course, one could always hit the gym...if they have enough money (or just move to California and ride a bike everywhere...if they have enough money).
