People often ask me how long they can expect it to take to see results on Nutrisystem. Often, they are very understandably looking for quick results. No one wants to be on a diet for any longer than is absolutely necessary. I heard from someone who said: “how long will it take me to start seeing a real difference in my body on Nutrisystem? I have an event to attend in two weeks and I am wondering if anyone is even going to notice a difference at that time. ”

I think that it is absolutely possible for to definitely notice some weight loss within a couple of weeks. The guidelines that Nutrisystem provides is around 2-3 pounds per week. In two weeks' time that could be anywhere from 4 -6 pounds depending on where she was in terms of the normal range. However, people often want to know when they will start to notice a difference for themselves. And many really want specifics in terms of the number of days. They are wanting to know if they will see nothing anything within the first week or within the first few days. It really is somewhat hard to determine this. I have heard people say that they lost weight in only a few days. And I have heard people say that it took them longer than a week. Generally speaking, the weight seems to come off a little slower for people with less to lose. In other words, people who start out as relatively small to begin with and who maybe only have 5 -10 pounds to lose typically see a bit slower results than someone who has more to lose. These are just generalizations based on what I am seeing, but everyone is different.

Let's look at it from a scientific standpoint. If you are looking at it from a caloric point only, if you have a 3500 calorie deficit, this will result in a one pound weight loss. The average Nutrisystem day is around 1200 calories. If you normally take in around 2500 calories (this is only an estimate since only you know your daily calorie intake,) then this would be a 1300 deficit per day. In three days, this would be 3900 calories or over a pound. In six days or a little under a week, this would be a little over two pounds, which interestingly enough is in line with Nutrisystem's own guidelines. Now, whether or not you will have the same results, I can not possibly say. But I am showing you this from a numerical standpoint.

And if you add in a little exercise, you might get better results or at least know that you are doing all you can to see a quick difference. So while I can not tell you exactly how long it's going to take you to see real results, I can tell you that many see some positive indications (or at least feel good about their experience) within the first week. I think it may be pushing it to think that you are going to see a huge number of pounds fall in only a week, but if the person who wrote me where even remotely typical, it was certainly not out of the question that she could have a five pound weight loss in two weeks, as that's around 2.5 pounds per week. And for many, a five pound weight loss is noticeable and significant.
