Is consuming alternative sugars effective for dieting?

What types of alternative sugars are there?

Lately, I've been eating chicken breast and salad on weekdays to lose weight, but I'm seriously on the verge of a food binge.

So I'm looking into sweeteners that are said to lower the calorie burden. If I cook with things like allulose instead of sugar, would it really be effective for dieting?

Stevia and allulose are the only ones I know, but I'm curious if there are more types.

I'm wondering if there are any side effects or precautions to take with something like this.
