What science says about aspartame:
Aspartame promises to reduce calories and aid in weight loss, but research results are conflicting. Numerous studies suggest low-calorie sweeteners may actually promote weight gain, while others show slight decreases in weight with use.
Occasional aspartame use does not seem to increase intake of sweet foods. However, long-term studies are needed to determine whether sugar substitutes encourage sugar craving or dependence…or alter appetite regulation over time.

Blood sugar control?
After taking into account body mass and calorie intake, sugar substitutes don’t seem to increase risk of diabetes. They also don’t interfere in blood sugar regulation in short-term studies.
Overall, research to date has not supported a definitive link between sugar substitutes and cancer. However, one recent study showed an increased risk of leukemia, lymphoma and myeloma in men consuming large amounts of aspartame.
Most studies have not found a link between seizures or altered brain function and aspartame. Studies involving migraines have shown contradictory results, but experts say the studies are often poorly designed.
