To the above response I had earlier about eating, your protein intake seems adequate, but you may actually need a little more. It seems like your carb intake is actually too low. I understand you're carb cycling but even your high carb day seems pretty low. you're gonna need the carbs for all exercise and cardio you will be doing. And yes, carbs are a greater fuel source than fat (even though lipid oxidation is the primary means of energy for endurance/cardio type activities) because a high carbohydrate intake is more beneficial than a high fat intake for endurance type of activities due to its ability to provide considerably faster aerobic energy transfer than from fat breakdown and yields a greater amount of energy than fat per quantity of oxygen consumed.

You also need to keep in mind, regarding protein intake, that when you are cutting you're going to obviously trying to expend a lot of calories through cardio and keeping your caloric intake relatively low. With those two things happening your body will break down not only fat, but muscle as well since you will not have a surplus of calories to build anymore. You will most likely need to up your protein intake greater than 1g/lb of body weight to reduce the breakdown of muscle as much as possible. I would think that somewhere around the 215 range would be good, but still hard to gauge depending on your genetics and your response to cardio and rest of your diet.

MaxPhysiology,

What's your meal plan?

Thanks,

So first, he needs more than 270 grams (over 1.5x bodyweight) and then suddenly
he only needs 215?

Make up your mind. The fact is, you probably don't need more than 1g/lb of bodyweight, even if you are cutting. You definitely don't need more than around 1.25g/lb. That being said, it probably won't hurt, but it's almost definitely past the point of being necessary, PSMF aside.
