I have written my approach elsewhere, but it fits precisely into your question. Here goes:
"Rest days" are not truly rest. They are usually very high in LISS, as I am usually doing a lot of farm work or taking a hike/snowshoe walk somewhere. On these days, I tend to keep carbs pretty low if possible, usually around 50g.
"Training days" are when I do heavy lifting. I tend to train fasted with BCAA, then lift, then eat a pretty heavy meal with about 100g of carbs after. It is almost always the same meal, a GF steak bowl with veg, hot sauce, and white rice.
On days where I am trying to perform, such as for a rugby game, race, Strongman comp, I will actually eat breakfast for once and load up on carbs, usually potatoes and fruit.
"They now look to a single and splendid government of an aristocracy, founded on banking institutions, and moneyed incorporations under the guise and cloak of their favored branches of manufactures, commerce and navigation, riding and ruling over the plundered ploughman and beggared yeomanry." - Thomas Jefferson, 1826
