I agree with that in the sense that most people when getting in to fitness start to realise how much you have to exercise to burn off excess consumption. And that it’s already known that ultraprocessed food is usually very calorie dense but can be nutritionally empty. I’m sure most who get into it seriously are aware dietary habits also need to change.

In running circles there’s a saying “you can’t outrun a bad diet”. There’s also “Abs are made in the kitchen”.
