Right. If the definition of "healthy" is "unlikely to be contaminated with food poisoning agents[0]," then meal prep services would seem as bad or worse than restaurant meals. They are "prepared at home" only for the last few steps, the food has been handled extensively by meal prep service employees, and has been shipped and possibly left at a delivery location for an unknown period of time in warm weather (I understand it is shipped in an insulated container, but the temperature control still must be less reliable than an actual refrigerator).

[0]Though I think GP and most others in this thread are defining "healthy" as matching their preferred fat/carb/salt/weight-control etc. parameters, and aren't even thinking about food poisoning.
