There are so many things that can affect our physical energy, although chronic fatigue always seems the most obvious. Many with ADHD say they feel exhausted all the time. It’s tough working harder to achieve some things.
Stress (related to ADHD or not) can also make you feel like you have zero energy. And it can deplete your adrenal system which will reduce your physical energy.
