Aspartame and other sugar replacements actually confuse your body and encourage weight gain. How can something called diet actually cause you to gain weight? Here is how.
Research shows that sugar substitutes can trick the mind into thinking sugar is actually being consumed, meanwhile, nothing of value is entering our body at all. Phenylalanine and aspartic acid, two ingredients found in aspartame, stimulate the release of insulin. Rapid, strong spikes in insulin remove all glucose from the blood-stream and store it as fat. This can result in hypoglycemia and sugar cravings. As a result you will end up making poor choices at meal or snack time.
Furthermore, the energy that usually comes with sugar consumption is absent from the body with a zero calorie beverage containing sugar replacements. This produces a natural desire to replace the energy you don't get from a diet beverage by eating more. When we eat carbohydrates our bodies produce serotonin to tell us we are full. Aspartame and its counterparts have demonstrated to inhibit the synthesis of the neurotransmitter serotonin, so your body doesn't know when to stop eating. Inhibition of serotonin also leads to food cravings, increased carbohydrate consumption and, ultimately, weight gain.
This research should cause you to question the diet label placed on the products you are consuming. Researchers also suggest diet beverages may be associated with binge eating, significantly increasing the chances of obesity in diet cola drinkers.
In contrast, a recent study with a control group that cut out aspartame from their diet resulted in a weight loss of an average of 19 pounds.
Artificial sweeteners not only can cause weight gain, they also are responsible for a slew of other horrible health problems. For more information, watch the movie "Sweet Misery".
