I tried the Nutrisystem diet about eight years ago, combining it with a couple hours of walking each day, and I lost more than forty pounds in one month. I ended up with severe gallbladder attacks. It turns out that men, in particular, are prone to gallbladder problems when they lose too much weight too quickly. I then lost whatever my gallbladder weighed because that was removed. I mentioned that in their forums, not as a complaint, but simply as a report, and a bit of a warning, and I was attacked by other forum members. A couple of days later, the thread was removed. I am sure there have been some changes over the years but, with Nutrisystem, you buy most of your food from them, choosing from their breakfasts, lunches, dinners and snacks. The idea is that any breakfast, any lunch, any dinner, and any snack from Nutrisystem would make up a good diet. There are a few things that need to be purchased fresh from the grocery, but most everything is supplied by Nutrisystem. It is a very easy diet to do, and it is very effective as long as you don't cheat. Other than their chocolate snacks, none of their foods were excellent, the best being on the level of a top-line TV dinner. Some of their foods are good, some are not so good, and others are awful, but the idea was that once you found out what tasted awful to you, you wouldn't have to order that anymore. After a few months though, I was losing only a pound or so a month, so it was harder to stay on the diet, and easier to become persuaded that it was too expensive to spend that kind of money on a couple of points a month. What finally did it for me was their snacks. At least half of their snacks were on the awful side, while most of the others were not exactly delightful, but I did like their chocolates. However, after ordering the chocolates as nearly every snack choice one month, they sent me only a couple of them, with a notation that they were on back order. The same thing happened the next month, and the snacks there were replacing them with were from the awful category, and since they still listed the chocolates as a snack choice, I got the idea that they were simply refusing to let me choose them. So I quit.
