Listen to your body. Hungry then eat. Tired then rest or sleep. Naps are a good thing too. If you're overweight balance intake to output better. If you can't read your body and there's something not right then GP it.
BTW it is amazing what you can detect without external help. I know people who can give you the time without using clocks or watches. People who never put on weight but simply know what food to eat for what their body needs. It's like instinctively eating more when exercising hard, less on lazy days, more on cold days, etc. I myself learnt when I can and can't eat food. For example I need to be awake a couple of hours before I can eat breakfast. I often skip breakfast and have early lunch. It's the way my body works.
My big thing is avoiding ultra processed energy or sports drinks. Also relying on supplements. I do get migraines due to, among other triggers, irregular or missing meals, except breakfast that is, so food intake is watched closely.
BTW artificial and even non sugar sweeteners like stelvia is a trigger. These are often in sports drinks and energy drinks plus hydration tabs too in some cases. A lot of "health" or some sports drinks go low sugar by aspartame. Imho avoid not good for you.
I go on I know but my advice is no short cut except good diet and healthy lifestyle supplements aren't really part of that unless health condition is detected.
