Usage of aspartame does not increase your blood sugar levels, during ketosis. It was found though a study, in which 31 people followed the “Spanish Ketogenic Mediterranean diet”, that is a type of keto diet that incorporates a lot of fish and olive oil. In which the use artificial sweeteners is allowed including aspartame and it probably won’t affect ketosis.
The participants had lost an average of 14.4 kg weight after 12 weeks, and it was found that their blood sugar levels had actually decreased by an average of 16.5 milligrams per deciliter. Hence, the use of aspartame did not affect ketosis among the participants.
As a powerful weight loss tool, the ketogenic or “keto” diet has gained traction in recent years and it involves eating very few carbs, with a very moderate amounts of protein, but a high amounts of fat.
This process actually diminishing your body of carbs, the keto diet induces the ketosis that is a metabolic state, in which your body actually burns fat, for fuel instead of carbs.
It can be very challenging, to stay in ketosis and in this, some people turn to the artificial sweeteners like the aspartame in order to help keep their carb intake very low.
