Is Sucralose Keto?
Sucralose is a calorie-free artificial sweetener with a glycemic index of zero. It won't kick you out of ketosis, but it may lead to gut health problems when consumed regularly.
Unhealthy Artificial Sweetener
Sucralose is unhealthy so it should be avoided on keto even if it is low in net carbs.
Dirty Keto is a common label for low-carb foods with unhealthy ingredients. You may still reach ketosis and lose weight with dirty keto, but it might also lead to health problems in the long run.
