That's a really good question. I am interested in what others who are more experienced than me, would say.
My best guess is that eating two would be absolutely fine, as long as:
1. You do have those extra points to spend. After all, if you do not spend them by your week's end, they are gone.
2. You follow the healthy guide lines, meaning you eat your daily portions of protein, veggies & fruits, milk, healthy oils and drink your water.
The only thing may arrise is that even though eating those extra 35 points are encouraged, some people do not loose as fast by consuming all the weekly points allowed. Each person is different.
One more hint... if you are going to eat them, I would eat them early in the week so you would have time to burn them off before your weekly WI. The danger would be that by burning those extra 35 points, you will not have any buffer for the enexpected hungrier-than-normal days or the un-planned dinner out.
My suggestion is to eat only One for your 16 points and save your spare flex points for later. You could enjoy your favorite snack 2 times each week! What a treat that would be.
