I tried NutriSystem two years ago and had mediocre results. I lost 3 pounds in one month and then nothing. The biggest problem I had with the program wasn't the taste of the food, it was the fact that they never got my order right. The initial order was spot on, but every order afterward came with 'substitutions' when the products I wanted were on back order. It got to the point after three months of sending food back and not getting what I wanted that I had to modify my orders down to three of the same dinners for a week, only about 2 lunches and forget about the snacks. The cereals for breakfasts were just as good if not less nutritious than basic types from our grocery stores like Cheerios, Raisin Bran, Total but cereals like Kashi are even more nutritious. So I stopped ordering breakfasts by month three. It got to the point that I was buying more grocery store food and my food bills doubled because I was too busy working to notice how ridiculous this whole program was for me.
Also, please note there are very high amounts of sodium and sugary preservatives disguised as very clinical/chemical ingredients (sodium benzoate, glucose or anything ending in 'ose' is a sugar-type preservative fructose, sucralose, etc.) in their products so they can ship and last for weeks/months with no refrigeration. So if you have high blood pressure, low blood pressure, heart conditions, IBS, Krohn's disease, edema, chronic yeast infections, chronic bronchitis or other chronic phlegm conditions you should seriously reconsider this diet as high amounts of salt and sugar no matter how well disguised will further enhance these problems and possibly create other health issues. You may see your waistline shrinking or your scale's numbers decreasing but your insides may be singing a very different song.
Now, I've heard and clearly I've seen success stories from their website, their ads and Tori Spelling tried it after her first baby...but I know those stories/people's results were NOT typical and they make that very clear in their legal fine print.
What's funny is that NutriSystem showed me how self-sufficient a person I am and how much of a better cook I am than they are. So, I've since taught myself portion control and had visits with a licensed and well-educated nutritionist. That was invaluable and actually less stressful on my pocketbook compared to the $400+ I spent every month on NutriSystem. I got my husband to participate with me in the kitchen and now preparing healthy meals and fun desserts is a family ordeal. This wouldn't have happened if I didn't go through what I went through with this diet.
If you try it then 'buyer beware'. But again, it really wasn't for me and I wanted to share my lil learning experience so you can consider those possibilities in your decision-making process.
Good luck!!
PS, my mother, 60 year old new grandma, lost 30 pounds in 6 months to prepare for a surgery by doing water aerobics 4 days a week, walking the dogs every evening and riding her stationary bike on the days she didn't have water aerobics. It's dedication, but it's cheaper than ordering a possible health hazard.
BTW: I tried this when I was 31 years old, working 60+ hour weeks and living in Utah. I did nothing but work, sleep and work out. So my results should have probably been a bit better than 3 pounds in 3 months. When I went off it, I lost more weight (15 pounds in 4 months) by eating more salads and drinking more water/water products.
