I found out this about Splenda-
Energy (caloric) content
Though marketed in the U.S. as a “No calorie sweetener,” Splenda actually contains slightly more calories than the same mass of sugar (391 kcal per 100 g vs 390 kcal per 100 g for white granulated sugar).[5] When sucralose is added directly to commercial products, the filler is omitted and no calories are added.
Note too that although the “nutritional facts” label on Splenda’s retail packaging state that a single serving of 1 gram (1 teaspoon or 5 milliliters) contains zero calories, Splenda actually contains two calories per teaspoon.[6] Such labeling is appropriate in the U.S. because the FDA’s regulations permit a product to be labeled as “zero calories” if the “food contains less than 5 calories per reference amount customarily consumed and per labeled serving.”[7] Because Splenda contains a relatively small amount of sucralose, little of which is metabolized, virtually all of Splenda’s caloric content derives from the highly fluffed dextrose or maltodextrin filler, or carrier, that gives Splenda its volume. Like other carbohydrates, dextrose and maltodextrin have 4 calories per gram.

It has more calories than sugar so why use it?
