Som det andra svaret säger finns det inget system för detta i pathfinder-reglerna. Så här är några husregler du kan använda. Jag skulle börja med att invertera reglerna för svält och törst .
När du blir uttorkad gör du successiva konstitutionskontroller och börjar ta icke-dödliga och då dödliga skador varje timme. Vidare blir karaktärer som svälter eller uttorkas trötta. Så att vara välmåttad bör invertera dessa effekter på något sätt.
Här är ett exempel på statuseffekt som jag har kommit på med som skulle kunna implementera detta:
Nourished
A nourished character can run as if she possessed the Run feat, and is granted a +1 circumstance bonus to Strength and Dexterity based checks, as well as a +4 circumstance bonus vs effects that cause fatigue or exhaustion. Becoming fatigued or doing anything that would cause fatigue removes this condition. Otherwise, it fades after one hour.

Profession (Cooking)
You are skilled at preparing exceptionally nourishing meals.
Check: Preparing a meal has a DC of 10 (for a decent meal), 20 (good meal), 30 (extraordinary meal), or 40 (legendary meal). You need ingredients, and a suitable kitchen or equivalent work space. Without a proper kitchen, you take -4 on your cooking check. Cooking without ingredients is impossible.
Decent Meal: Pretty standard fare. A decent meal grants the nourished condition
Good Meal: A good meal, the kind you could expect to find in a particularly expensive restaurant or luxurious inn. In addition to the effects of the nourished condition, a good meal grants a +1 circumstance bonus on fort saves for the condition's duration.
Extraordinary Meal: An incredible meal, the like of which most people will experience only rarely, unless they are quite wealthy. In addition to the effects of a good meal, an extraordinary meal grants 1d8 temporary hit points.
Legendary Meal: A meal of legendary quality. As word gets around of your skill, kings will fight to have you in their kitchens, and beings from other planes will seek you out to experience your masterful creations. A legendary meal grants the nourished condition, as well as a +2 circumstance bonus to all saves, and d8 + (Cook's HD) temporary hit points. Such a meal is so good that creatures who taste it can't bear the thought of dying without tasting it again.
Action: Preparing a meal takes one hour, although a particularly intricate or important meal may take longer, at the GM's discretion.
Try Again: Yes, but every time you prepare a meal any ingredients used are consumed.
