If I use a 4 days a week 5x5 powerbuildng program vs my former volume based, 4 days per week program I should logicaly drop my carbs correct? This kind of training is less dependent on carbs as far as I know then volume training. My cardio is held to three 30 minute sessions a week on none workout days to assure I dont hinder my strength/size gains from this program. I have never done any kind of powerbuilding before but I do feel it will bring out the needed results and stimulus my body needs for more size. I just dont want my old diet plan to sabatoge my new programs by assuming it will work here as well. How should I modify my diet to suit a powerbuilding routine?

My diet now looks like this:

Meal 1
1 scoop egg protein
8 egg whites
1.25 cups oats

train (15 grams bcaa sipped)

Post Workout: (removed on off days)
45 grams whey
60 grams dextrose
5 grams creatine
10 grams glutamine

Meal 2
1 cup oats
8 oz cooked chicken breast

Meal 3
3 scoops protein blend (50 grams protein)
(egg, whey, casein)
2 tbsp natty pb

Meal 4
9 oz can tuna
1 oz peanuts

Meal 5
8 oz cooked chicken breast
1 oz peanuts

Meal 6
2 tbsp natty pb
45 grams casein

I hardly ever post, but been lurking for years.

I've been following Bill Starr's 5x5 program for some time with consistent strength and lean mass results. I can see a definite difference in muscle density.

Have you considered keeping your resistance training to three days a week? His approach has a cumulative, taxing effect on the CNS. If you're pushing the Squat, Bench, and Deadlift with intensity, your body is going to get plenty stressed. And when you add your energy system work, that totals to a heck of a lot of demand on your CNS even with a surplus of calories and sleep.

For what's it worth, I've found that cycling carbs is very effective with this routine.

If you're looking to gain, stick with the basic Beverly approach, but make your lifting days have a higher total of carbs in comparison to fat. On non lifting days, drop the carbs fairly low and increase the fats. The protein will stay about the same. A bit higher on non lifting days.

If you're looking to maintain, again, stick with the basic Beverly approach, but play with high/med/low days. Maybe one high carb day a week, probably on Monday if you're following Starr's program somewhat because his Mondays (or Day One) are heavy resistance days. You could do low carbs on non lifting days, and medium carbs on the other two resistance work days.

The idea is to play with carb intake. But in my experience, you do not need as many carbs with this type of training. A higher fat ratio works very well.
