Summer is when I will typically have some fruit because that's when it's in season (just berries and melons, though). The rest of the year I don't eat it much. I also tend to eat a lot more fresh veggies this time of year instead of frozen because they're more available and cheaper this time of year.
Do I plan to change my carb allowance? Nope. I just "spend" it a bit differently in the summer months than I do during the rest of the year.
