For me my energy level is quite good, while on cycle when I workout in the morning, when I have worked out at night after a long day is not as good, what I do is have some complex carbohydrates, like whole grains or vegetables before my workout.
For me eating small carb meals thorugh out the day help me maximise my glycogen storage, the amount of carbohydrates you eat determines the amount of glycogen stored in the liver and muscles, which inturn greatly affects your performance.
Even when cutting and consuming low amount of carbs I still divided them up throughout the day, and this really works well for me.
This is exactly what I do daily. Spread those carbs out so that my body never feels that crash effect. I am cutting hard right now but what little carbs I am eating I spread over the entire day. Great post for discussion Radar.
