A clear balanced analysis by Dr Bret Scher, now with Metabolic Mind. Same method used when he was with DietDoctor. His conclusion is to reflect on why you are using artificial sweeteners in the amounts found in 'keto" desserts, etc.

His solution is what I have been doing since joined OptimisingNutrition.com. Use real whole foods like mixed berries (Ty Costco) mixed with 0% Fage yogurt, LF cottage cheese, sometimes blend with protein powder (has tiny amount of Sucralose) into amazing "ice cream", etc.
No "low carb" cookies, brownies, breads, etc. If you eat satiating, nutrient dense foods, no need for sweeteners in the ridiculous amounts added to recipes.
