I've been experimenting with the two, and the amount of satiety that I get from an identical meal with potatoes is noticeably less than if I ate sweet potatoes instead. Seems like the potato starch is converted completely into glucose and thus causes a greater insulin response, but the fructose in the sweet potatoes should interfere with satiety as well. I keep testing it with the same result; anyone else experience this?
For what it's worth, I'm eating about 2 golfball-sized purple potatoes per day with a negligible amount of carbohydrates from other sources.
Edit: Interesting answers here. You know, it's funny because when I eat sweet potatoes I eat less food in general but I don't lose fat, but with potatoes I eat more food, more carbs but I lose fat. This must be the result of the higher fructose content in the sweet potatoes.
