This story in the NY Times examines the market for prepared, delivered “diet” food. They are expensive, and the reviewer says that most taste (to paraphrase) like $#/+. There was one he liked ($44 a day!) that he had some success with. He says he lost 10 lbs in 3 weeks, so more power to him!
PAST 50 and pushing 230 pounds, I decided that this spring I would try to get down to a healthier 200.After online searches and conversations with friends, I decided to compare the offerings of four companies: Zone Manhattan, Chefs Diet, Nu-Kitchen and eDiets. All four would deliver the meals to my door in Brooklyn. Three deliver daily, while the fourth, eDiets, sends a large package once a week. None of the companies knew I was a reporter.
I say: triple your green veggies, add sweet potatoes and beans regularly, and use a range of spices (ginger; garlic; tumeric; mustard; basil; onion…) to give food flavor.
