Overall, my macros for an entire day of eating are 30 per cent protein, 30 per cent fat and 40 per cent carbs. I always eat my higher carb meals around my workout.My pre-workout meal consists of a lean protein and a complex carb, eaten 60 to 90 minutes before I hit the gym. I often opt for white rice, as it’s easy on the digestive system and is fast acting. I train with quite heavy weights, so having my energy stores full prior to training ensures I maximise my performance.Immediately after I exercise, I will have a protein shake. Protein consumed within 30 minutes of my workout kick-starts my muscles’ recovery process; protein replenishes my muscle glycogen, reduces muscle soreness and fatigue, and promotes muscle repair and growth. I find whey protein isolate is best for fast absorption.The meal after my post-workout shake is also higher in carbs, with a lean protein. I usually have brown rice in this meal due to its higher fibre content, which leaves me feeling fuller for longer.Follow Lauren Simpson’s journey on Instagram.Looking for more motivational stories?
