I also wrote an arcitle on carb cycling, so ill just give you a small clip of it below to help you out:
Lets take for instance your average of carbs would be 300g during the given week, instead of eating 300g every single day you may do days of 150g (low), 300g (medium) and 450g (high) while cycling your fat intake (lower on high days, and higher on low days) while keeping protein pretty steady throughout the week. Is there any real benefit to this? It can help you swing into anabolic and catbabolic environments especially while dieting. Usually on lower carb days your overall calories will be lower and on higher carb days they could act as refeeds where t3, leptin, and hormone levels will raise and may aid in further fatloss/weightloss for your given goal. In the offseason this may not apply because of being in a constant surplus so it may not have a great benefit besides enjoying higher fat foods on your low carb days and higher carb foods on your high carb days. Lets note that while cutting it may benefit again for burning fats for periods (low carb days where you may do strictly LISS cardio (Low intensity) where you are tapping fat reserves), or on the other hand higher carb days and you utilize a workout + HIIT Cardio (which utilized glucose aka carbs) for glucose/fuel where they are in an abundance.
This wil be my starting outline for someone on a medium day above. So lets take 2500 calories and calculate it out. Lets say the individual is 175 pounds and a male athlete.
20% of the calories to fat = 500 calories / 9 = ~55g
1-1.5g protein we will just setlle at 200g which is 800 calories
so that is 1300 out of the 2500 right there in protein and fat which will be allotted to carbs .. 1300/4 = 325 g
200g Protein, 325g Carbs, 55g Fat will be our medium day at 2500 calories
For a lower carb day lets drop calories by 200 and on higher carb days they will raise to 2700 calories.
Lower Carb days lets drop our carbs down to 175g, keep protein at 200 and raise our fats to hit 2300 calories
200g Protein = 800 calories
175g carbs = 700 calories
1500 out of 2300 leaves us with 800 calories / 9 ~88-89g
Now lets set up the high day:
2700 calories and 200g protein = 800 calories
lets raise carbs to 400g = 1600 calories
Leaving 300 calories for fats around 33g (yes these are low but its not like it is everyday)
