Do Artificial Sweeteners Affect Blood Sugar?
Last week, I started an experiment to better understand how different foods and lifestyle choices impact blood sugar, using a constant-glucose-monitoring device. Today, I’m sharing the results of the first experiment: Do artificial sweeteners affect my blood sugar levels? While the answer may seem obvious – artificial sweeteners contain no sugar – some people still believe there may be an effect. For example, artificial sweeteners could potentially under some circumstances affect insulin levels, indirectly affecting blood sugar and ketone levels. Planning the experiment We designed the following experiment: I would drink a 17 oz (0.5 liters) sugar-free, artificially-sweetened, beverage in 15 minutes. Then, for the next two hours, I would observe my blood-sugar levels using the Dexcom G5 mobile app. To increase the reliability of the experiment, I made sure of four things: 1. That the soda I drank would be caffeine free. 2. That I didn’t eat or drink anything, nor do any form of exercise, 2 hours prior to and after drinking the soda. 3. That my blood sugar was relatively stable for at least 30 minutes before drinking the soda. 4. That I would do the same test at least twice. Continue reading >>
