I don’t think there is an effective healthy eating regime that overlooks protein. For a meal or snack to be healthy and contribute to weight management and emotional regulation, I’d suggest it should be a combination of natural slow release carbs, healthy fat and a bit of protein. I’d also suggest that most healthy eating regimes are probably based around 6 meals a day (breakfast, snack, lunch, snack, dinner, snack)
The DWF, or daily workout and food is aimed at giving you some basic conditioning ideas. For some it’s the only thing they do, for many it’s just part of your training day.
Most days you also need to work on skill ( I often focus on gymnastics), Strength and therapy drills: I need always focus on my vulnerability to Plantar fasciitis, Patello-femoral and back pain. By having a sensible self applied therapy regime, you can stop the problems before they start.
