I had a question at the gym the other day that was also kind of in the back of my mind and it made me investigate the subject a little further. Artificial sweeteners are kind of a big thing for people that are starting on diets right? They’re great because while you are trying to give up all of your favorite foods this artificial miracle comes along and says, “you can still have extremely sweet things, I have no calories!” While the thought behind artificial sweeteners is great, the evidence that supports the logic behind eating something without any calories and losing weight is possibly not so great. I say possibly because unfortunately there is a lot of contradicting information in scientific and medical journals that left me scratching my head. However, I did draw a couple conclusions based on what they all said. Let’s dive into this topic just a tiny bit, without making you fall asleep whilst reading this.
So, the journals that are all FOR artificial sweeteners say that they do NOT increase appetite while consuming them. They do NOT make you eat more and they do not inhibit the suppression of appetite after a meal. So you can drink the diet drinks, have your cake and eat it too.
On the other hand, they nays say that consuming artificial sweeteners disrupts your body’s appetite control mechanisms and in turn you eat more. A couple of studies looked at the thermic effects of food and how the artificial sweeteners do not have as strong a thermogenic effect and therefore do not suppress appetite as much as food with calories.
Both sides had compelling arguments and had similar ways of figuring out what effects artificial sweeteners have on human consumption of food and yet had different outcomes. Why is this?
Well, I’m not about to tackle that question entirely but I will say that there has got to be other factors that some of these studies aren’t looking at. Some of the results differed because they were done in “healthy” people who didn’t regularly consume sweet beverages. Others were only done with animal models using rats.
One thing that these studies cannot fudge though is the numbers in terms of the effects each sweetener had on insulin levels. For those who don’t know too much about insulin, in just a few words this is the hormone that allows energy to get into our cells. Conversely, it dissallows stored energy (fat) to leave our cells. So if insulin is around, we are not going to be burning fat. Period. Now, the artificial sweeteners didn’t have as much of an effect on insulin as sucrose (table sugar), which is to be expected; but the fact that it did have an effect has to say something (this point was made by the way in a study that was FOR artificial sweeteners). So either way you look at it, if you are drinking diet soda to cut calories out you may have accomplished that, but just remember that you will not be burning any fat either because of that much feared insulin spike.
