If you choose to to less High carb days(á-la Anabolic Diet, one per week) you might want to go to something like 60% Carbs on that day, mainly from glucose: cassavas are perfect for these, sweet potatoes have fructose in them(about 5gr per 100gr of edible potatoe) so be aware of the quantity you throw, and to less of my liking but still an option you have white rice and skinless potatoes.
A few things: fruictose does not raise insulin so much, since it is metabolized by the liver, and this is the mainly reason why you want glucose instead of fructose, because the latter ends up refilling intramuscular glycogen stores(assuming they are depleted to some extent).
It doesnt mean you can get some fruit, because you can. Banana is ideal since the glucose frutose ratio is more favourable to fructose-malabsorption folks. But bear in mind to limit the fructose eaten in one sitting to 20-25gr, no more than that.
Personally, i prefer to cycle carbs in a more spreadout fashion, not having a day of all-or-nothing(in spite of recognizing some benefits leptin-wise and muscle growth-wise), and get maybe some carbs after each workout. So if i go train 3 times per weel, i have some carbs after the training, and thats it. For the rest of the time, higher-fat, same protein.
Hope it helps
