Here's the thing about creatine: it's the final stage molecule before ATP (energy used to perform muscle contractions). Because all of your carbs are inevitably broken down to creatine phosphate and then adenosine phosphate (ATP), there's really no need to supplement post workout. The benefits truly lie in the pre workout stages. If stores are optimal at the onset of activity, anaerobic activities like sprints or heavy lifts can be performed for longer. Keep in mind, when this molecule is stored, a lot of water is stored with it. It does nothing for anabolism, although you will notice the scale showing an increase weight. It's just water.

Post workout and during the day, just balance that diet. What you have above would be great for someone trying to cut. But you want to get bigger. I can get technical on how the carbs play a role here, but ill just sum it up with carbs equals better energy and muscle mass.

Insufficient dietary carbs puts the body in a hypo state. Since carbs are the desired source of energy, the body will synthesize it from other sources like proteins. Muscles are made of proteins and the working muscles are where the deman is. You're training to grow them so you need to feed them what they need to meet their energy demands. If you don't, they catabolize for the sake of meeting energy demands. Catabolism and anabolism are antagonistic from one another, thus they can't take place simultaneously. Meaning, no building of muscle tissue if the proteins are being used for energy.

Bump up them carbs bro. Simple carbs at breakfast and post workout, and complex during the day. That pic you have for the 3rd meal would be perfect for the last one of the day (zero carbs outside of the vegs), unless you workout close to that meal.
