Bruh, I’m training for a marathon right now, zero sugar for the last 10 weeks (no soda, cake,candy,icecream, ), no fast food, no coffee , no smoking cigarettes, no alcohol, high carbs, low red meat, no bread, no cheese. Before my ten week training I drank 7 cups of coffee, ate a entire family size pack of Oreos EVERY NIGHT, pizza , hamburgers, icecream, beer. Conclusion, less anxiety, better sleep, better man drive 😊, clear mind, more relaxed , no racing thoughts.
