I believe the Nutrisystem shake is safe especially if it's used in addition to eating real food. Nutrisystem Protein-Powered Favorites 5-day weight loss kit. The mobile web version is similar to the mobile app. Share Facebook Twitter Pinterest. Learn more about Amazon Prime.
This is a patented type of soluble fiber that comes from corn that is added to food and supplements to increase fiber content. In other words, we don't absorb any calories when we eat it. While more studies need to be performed, if this study is corroborated, I think resistant maltodextrin is might be one of the main active ingredients in the NutriSystem shake.
The Nutrisystem shake label does not tell us how much resistant maltodextrin it contains. Several products previously reviewed here have contained glucomannan konjac. Just a few include:. Over the years, there have been several studies on Konjac and weight loss.
For example, in this study, lasting 3 months, 4 grams a day of glucomannan -along with a low calorie diet- showed more effective for weight loss than a low calorie diet alone. The author of this review of research noted grams was appropriate for helping weigh loss.
In this review of research , the authors noted modest weight loss but no change in body mass index with glucomannan use. While not all studies have shown konjac fiber works, there are enough that I think there might be something to it.
I believe these 3 ingredients have evidence that they might slow down digestion and help us feel full, longer. This in turn, could lead to weight loss in some people — especially in those who are eating fewer calories than usual. The ingredients are listed in order as they occur in the ingredients list above to give you an idea of whcih is present the most and least.
Lets briefly touch on some of these ingredients. According to this list fructose , which is listed first, makes up the most of the sweeteners in the shake. Fructose is controversial in some circles so, let's discuss it briefly and calmly. While the amount of fructose in foods is very low and not to be of concern, higher levels of fructose, can raise triglyceride levels.
This is a risk factor for heart disease. High levels of fructose also appear to increase the risk of insulin resistance. While fructose does not raise insulin levels that's good , it also doesn't appear to raise leptin level s either that might not be so good.
Leptin is a hormone made in fat cells that is a signal for us to stop eating. If leptin release does not occur, we might to eat more food — and calories. This same study linked to above noted fructose also stimulated ghrelin production too. Ghrelin is a hormone that tells us to eat.
The important thing to remember that we would need studies to know if the NutriSystem shake did any of this. So how much fructose is too much? Well, according to this paper titled Fructose: To say fructose and high fructose corn syrup is controversial is an understatement and that's why I wanted to calmly present some of the evidence here. This is not all of the research on fructose and that's why I feel it's best discussed with someone who knows about what you might be eating to make a more personalized assessment.
Registered dietitians RDs are very good at this and you can find one in your area by going to their website — EatRight. Is the fructose in the Nutrisystem shake too much?
Is the effect of fructose blunted because of the fiber that is also in the shake? I don't know the answers to these questions. While I think most people on NutriSystem might probably be consuming less fructose than the average person, I would not be surprised if fructose is eventually removed from the ingredients.
For more on fructose, see this video from NutritionFacts. I am not sure why. This sweetener is also known as lo han or lo han guo. It has zero calories and is over times sweater than sugar. For a run down of various natural and artificial sweeteners, see this article from Nutrition Action.
I used chocolate flavor for my taste test, although Nutrisystem also has coffee and vanilla flavors. When you tear open the packet, I could smell the chocolate when I brought it close to my nose. I did as directed — except I mixed the contents for 10 seconds using my Vitamix. My opinion is that I liked the taste. The shake was not thick or watery. It was not gritty either. It had a light chocolate taste that I thought was pretty tasty. When I drank all of the shake, there was no significant product left at the bottom of the glass either.
The picture to the right shows what it looked like when I made it. I also used the glass that was included when I purchased the shakes. I think it did for about minutes or so. I believe the effect was greater when I mixed it with 10 oz of water. It still tasted good when I mixed it with 10 oz of cold water.
I believe the appetite reducing effects of the shake are the result of the volume of liquid used, along with the fibers and protein mentioned above. Do you have to mix it with water? One could mix it with milk, almond milk, flax-seeds, etc. While this can adjust the taste, just remember that this will also increase the calories of the Nutrisystem shake.
The same shake can be used by both men and women. While there may be differences in how men and women metabolize supplements, I am not aware of any evidence that the shake works differently in men. I expect it to work the same in both genders.
While I'm not aware of any studies comparing weight loss in those who only used the NutrisiSystem shakes verses those using the shakes in addition to the whole Nutrisystem program, my guess is that in those who ate fewer calories, drinking the shakes alone could lead to some weight loss.
Keep in mind that this is the same logic with any weight loss shake too. The shakes help by substituting a lower calorie meal for a higher calorie meal we might normally eat. Yes, the ingredients list above mentions soy protein isolate. This makes up some of the protein in the shake. There is no caffeine in the Nutrisystem shake. That's good especially those who are sensitive to caffeine. There are many ingredients in the NutriSystem shake but as far as I can tell, 3 ingredients appear to have the most evidence to help weight loss.
I present these for those who are on a budget and want to do a little bit of experimenting to try to make their own homemade weight loss shake.
Another option is to try using a ready made fiber supplement like Metamucil. See my Metamucil review for more on that. Learn more about Sponsored Products. See a problem with these advertisements?
