dont' know much about carb-cycling, as i've never tried it myself. at first glance, though, your plan looks a bit high-carb in general... as it is, you are getting on oyur high carb days, over 1300 calories from carbs alone.
i don't know that 200 grams of carbs is low-carb in anybody's book, on any day.
as i understood it, carb-cycling was supposed to give you the benefits of low-carb without letting your body adapt to low-carb.
wouldn't you want to either lower the whole plan (i.e. high carb is 150g, medium is 100g, low is 50g) or at least use a broader range starting from the same place (so high carb is 340g, medium is 175 g, low is 50g)? sorry if i'm missing something here... but this sounds much better to me...
also, what are your other macros like? and how many calories are you taking in? are you going low-calorie too? or are you gonna try this on a high calorie diet for some reason?...
i'd love to see a more complete breakdown of your plan, because to be honest, i'm not sure that the one you've written about above will actually do much in terms of weight loss.
it seems to me like a random fat American's diet: somedays i eat really high carb, others i eat less high carb but still high carb, and other days i just eat pretty high carb, but it's all basically random.
