So i bought a digital food scale and im really loving this thing... but today i conducted a little experiment... normally when i cook chicken on the george foreman grill it does get smaller but i dont think too much of it... today i weighed the chicken before cooking it and it camee out to 8oz-8.2oz.... after cooking it... it came out to 5oz-5.2oz.... thats 3 oz difference... which is close to 100 calories!!! so here is my question... Should i weigh my food before i cook it or after? im mostly concerned with meat products.... also for like brown rice or beans, if it says 1/2 cup.. do i measure it before i cook that to? ( most of the time it says dry) any other tips on weighing food? thanks in advance!
