I saw a poster in my gym that noted that Old-fashioned oatmeal has a GI of 40, then noted that Instant Oatmeal has a GI of 65, or high GI. I looked at the macros, and noticed no difference. Also, I have recently bean to eat Instant Oatmeal w/ splenda, cinnamon and 1.5 scopps of ON whey after I work out. I work out first thing in the morning on an empty stomach, so this is my first meal as well as my PWO meal. Any issues w/ eating this after my workout? Thanks.
