Initial Question: What is best for breakfast to have the day active?
My reply:
You’d want such a meal to be balanced, in terms of carbohydrates, protein, and healthy fats. By all means, avoid processed stuff and junk sugars.
You’ll need a steady source of energy from a palatable and satisfying meal.
Unfortunately, folks do not tend to look at breakfast as a full course meal and in my opinion and that is a mistake. But it’s a process to learn to change such conditioned societal norms.
However, for a particularly active day, as you are inquiring, you got to do what you got to do!
