You are allowed more than one starch a day - just depends what kind!!! Potatoes, pasta and rice are limited to one meal per day - but otherwise you can have barley, couscous, buckwheat, cornmeal as well as other starchy vegetables such as squash, peas, corn, etc.
If you want to eat bread as a starch you must use some of your 35 weekly points - ditto for multiple servings of potato/rice/pasta - you can have them more than one a day if you choose, but would have to use your points in that case.
Also as mentioned food is not really "unlimited", in that we are supposed to gauge when we are "satisfied" - it would be grand if we could eat as much as we wanted...but unfortunately most of us would not lose any weight!
As for snacks - we are not limited to fruits/veg - but can eating basically anything as a snack (protein/starches too)...at least that's what I believe???
Congratulations on your amazing weight loss so far and continued good luck!
