There are many ways you can do carb cycling.... The most well known one on the board is TPs, but it is not the only way.
In essence, you cycle carbs each day. TPs is something like:
High
low
no
high
low
no
But you can do it any number of ways, such as:
high

Etc etc.... The level and frequency of the high days will depend on things such as your BF%, your training, your carb sensitivity and the severity of your no/low days. Generally speaking, if your BF% is really high I recommend you don't do the high days every 3 days.
The level of carbs you have on the different days also depends on you and what type of cycle you are doing.
TPs is:
no =
1.5g of protein
no starchy carbs
lots of green vegetables
adequate fats (inc. fish oils)
low =
1g carbs per pound
1.5g protein
green vegetables
adequate fat (inc. fish oils)
high =
as many carbs as you need until you are psychologically and physically satisfied (not stuffed)
1.5g protein
green vegetables
low fats (inc. fish oils)
TP suggests on high days not to count carbs but many people do - just
because otherwise they go overboard.
