I can say the women’s jumpstart Nutrisystem package sold at Walmart (and I assume the men’s) does work. Entering the third day and down 3 lbs.
Cost: 40.00 for the packet for one person and another about 40.00 for the fresh food they want you to get.
Taste, not bad; and if we have one complaint, it’s being positively stuffed with food every two hours.

Cost, about 16.00 a day, figuring 80.00 divided by five.
Taste—pretty good, for diet stuff.
Kitchen necessary—a fridge but not a freezer; plus a microwave.

I definitely have had worse. Typical day: breakfast, a small! muffin; midmorning a quarter cup of salted nuts mixed with dried fruit; lunch, a small bowl of carrots, cherry tomatoes, cucumber and a half cup of lettuce with a tablespoon of ranch dressing, plus some little item like a piece of string cheese; midafternoon, 8 oz of yoghurt plus a quarter cup of fruit; supper, about 8 oz of not-bad beef with veggie soup with a cup of lightly steamed veggie such as broccoli, late snack about 3/4 cup of cheddar popcorn. By the time I’ve eaten all that, I’m about ready to say this is overkill and I don’t WANT to eat much tomorrow—
But then I get up and I’m down a pound.
I think the trick is keeping the metabolism high and working on a lot of raw garden veggies that aren’t easy to digest.

I’m also saying that little salad is right tasty. I can live with this. Price for food is a little high, but there’s no waste, and you end up eating healthier and less, so a few less trips to McDonalds might be easier on the wallet.

We’re going to try another diet to follow up, which uses special-sized containers (you’ve probably seen it on tv) to denote acceptable sized servings. Eat anything you want, but it has to fit.
