For me the easiest approach is choosing a few basic meals and rotating the ingredients instead of cooking something completely different every day

I usually adjust my food based on how much training I am actually doing rather than following the same diet every day

When I have a less active week I naturally need less food so I reduce portions slightly

Fats are something I do not like pushing too low so I set a reasonable minimum and use carbs for most of the remaining calories

I keep a few easy snacks available for days when I get hungry between planned meals

I do not try to force six meals into my day when my schedule is unpredictable

Training harder can make a noticeable difference in appetite so I take that into account when planning meals

I usually look at the trend for a few weeks before changing anything because daily changes can be misleading

I stopped buying supplements based on social media recommendations because most of them made more sense in the marketing than in real life

I’d start with protein because it helps with fullness and maintaining muscle. Then set a reasonable amount of fat and use the remaining calories for carbs.
