do i take phaze 2 with every meal or just starchy meals?
eg if i only have one meal with starch eg pasta for dinner?

Only with starchy meals! If you take Phase 2 when you're not eating starch, it won't do anything. Like if you're just eating a steak, don't bother. No point in taking it with every meal, just starchy meals.

Phase 2 can only block starch when you eat starch, so you need only take it at those times.

no point in taking a stach blocker if you're not eating starch.
