Stevia unfortunately has effects on hormones, it was actually used as birth control by natives since it supposedly raises estrogen. Allulose is probably the best “sugar alternative” but in the end the best way to go is eat minimal amounts of real sugars in foods with fats and other stuff so you feel more satiated and eat less.
Also sweetening stuff with fruit will keep the glycemic index way lower. I use dates and bananas to sweeten most things, if I need more concentrated there’s honey, date syrup, coconut palm sugar, maple syrup, just note that their indexs are still much higher than fructose in fruit but still better than sucrose (table sugar.)
