Q: when on your last week of prep what carb do you prefer to go up on the last days?
Example W,thurs.fri.? Sweet potatoe, rice cake, oats or brown rice
A: This is a good question but not an easy answer. Everyone is so different and it depends on your body and how it responds to each carb, just like fats and proteins. The time leading up to a show, you learn what sits well and what doesn’t. Some people do really well with oats and rice and not so well with the starchier, potato type carbs like sweet potatoes and yams. You want to find the carb that sits well with your tummy and doesn’t bloat you. For me it is all about the oatmeal. I love oats and they sit nice and tight in my stomach without feeling bloated. It really is trial and error. Rice cakes are super light in my stomach too. Also, because you cut back on water, the drier foods such as dry oats or rice cakes tend to soak up extra water in your body, rather than the yam/sweet potato and rice that carry water.

On another note, I do not play too much with my carbs the last week. I keep things pretty consistent. Some people do better with adding a few extra fats and staying away from the carbs and others vice versa. Again, it just depends on your body and how you respond to different foods but also where your physique is at, at that time.
Wish there was a more specific answer to your question but it is all so variable!
