Estimate portions
Fist
etc
I mean almost everything they list uses a fist or something the size of a fist to estimate the portion.
So how about we not confuse it and just use the fist. lol
Some things the say something like tennis ball then later they list something else using a tennis ball or fist. lol
Best thing to do when measuring portions is just use fist size portions.
The book covers this.
