For breakfast, eat some hot porridge, cook 2-3 chestnuts (tonifying kidney) or walnuts and sesame seeds, and a assorted vegetable, so that you will be energetic all day.
The amount of one person: just grab a handful of rice, 2 chestnuts (plant protein plus kidney), 3 walnuts, 2 red dates and a handful of black sesame seeds (or black rice). What nutrition!
The porridge cooked in a small rice cooker (ceramic) is very nutritious, so you don't have to watch the cooking, saving time and effort. Get up early in the morning and get some food, then go back to sleep, and the meal will be cooked when you wake up.
Good wishes!
