“cheesecake: for example what type of things can you subsitute it for???”
If you’re gonna eat cheesecake, EAT CHEESECAKE already. There is nothing worse than a cheesecake that has been de-fatted, de-sugares, de-sour creamed, and so forth. You can try using neufchatel cheese (a lower-fat version of cream-type cheese), but come on, who is kidding whom? If you are diabetic and desperate, then make it with Splenda, but it will not taste the same, no matter what ANYONE promises you. It is only for someone who really is going nuts without the cheesecake but cannot eat the real stuff. Have the real thing, but stuff yourself with lots of fresh veggies first, and maybe some soup, so you are less inclined to eat a LOT of it in one sitting.
