New resident soon: what would be the best diet for optimal energy for a sustained nighttime physical activity?

Carbs, carbs, carbs. Whole grain starches are better than the whites like bread, brown rice, beans which are great source of proteins too and also fresh fruits and dry like almonds. You will feel more energized if you distribute one portion of starches in each meal all through the day and have a bigger portion with breakfast to have a bust to get your day started.
