Can artificial sweeteners from diet sodas affect your weight? My six
hour experiment the other day implies that the answer might be yes.
results can be seen above. I drank the Pepsi Max (17 oz.) after about
an hour. The black line is the blood sugar and the purple line is the
Pepsi Max and other products with artificial sweeteners are thought
not to affect peoples weight, as they contain no calories. That’s an
oversimplification that ignores any hormonal effects and resulting
hunger. If the sweeteners slow your fat burning and increase your hunger
they will of course affect your weight – calories or not.
What is clear from the experiment is that something
happened. The ketone level dropped precipitously. My interpretation is
that this potentially could result in a decreased fat burning, making it
harder to lose weight. Perhaps this is due to insulin release, perhaps
I wonder: What if your fat burning is impaired for more than five hours, every time you ingest artificial sweeteners?
objection: Was the culprit the artificial sweeteners or the caffeine in
the soda? This experiment can’t tell, but I would gladly bet money on
the sweeteners. Perhaps I’ll do a similar experiment later, drinking
black coffee instead.
