Details on the Grilled Cheese Aspiration (Sims 2)?

I searched the web, and I didn't find enough info on the aspiration benefits to my liking. For reference, the benefits, in order are Bottomless Stomach, Slower Bladder Decay, Paint Grilled Cheese, and Conjure Grilled Cheese (Primary aspiration only - not available as secondary aspiration benefit).

I know what Slower Bladder decay does - An additive 12% slower bladder decay. But I'm not sure about the details of the other three effects.

Bottomless Stomach - Fitness points are lost 50% slower when over eating.

Q1) I've heard there's a bug where fitness point a gained, not lost (still at 50%) with this. Is this true - you'll lose weight by overeating?

Paint Grilled Cheese - adds option sims to specifically paint grilled cheese sandwiches.

Q2) Are these paintings automatically considered masterpieces?

Q3) What prices can you get for them (is it helpful for the fortune aspiration)?

Conjure Grilled Cheese - adds option on the sim to conjure a grilled cheese from their comfort and energy motives to fill hunger. Sandwich is consumed immediately and cannot be shared.

Q4) Can this be done repeatedly, or is there a cool down?

Q5) Will sims automatically do this to prevent themselves dying by starvation?
