While some non-sugar sweeteners have zero or very few calories, there is a downside: Sweeteners found in diet soft drinks, diet foods, and on restaurant tables next to the sugar packets go unrecognized by the brain. They're essentially invisible to your brain's satiety centers, so it doesn't count them as real food and still desires to be fulfilled by calories somewhere else.
There's no clear-cut proof on the effects of these sweeteners - both on a health level and a weight-loss level - but we do know one thing: Prehistoric man wasn't putting a sugar alternative in his water. Artificial sweeteners, while lacking the calories, may have side effects like intestinal problems and headaches. If you're having a hard time losing weight or don't feel well, these are some of the first things to cut out, even though they can be an alternative to high-calorie sugars.
