This is a great topic and the right emphasis
I suppose it really boils down to what you are trying to achieve and what the starting point is. I see a lot of endurance athletes and the podcast VERY diet focused - and sometimes the focus is well founded and grounded in good knowledge and sometimes it isn’t
I often wonder if ppl are trying to “look like a cyclist” rather than be a good athlete. I see a lot of calorie restriction and hidden dieting which can’t be healthy. Particularly if making a certain weight or a certain look is compromising health/power/life
So can you eat Popeyes every day - maybe if you are 17. But not for long. A decent balanced diet founded in whole foods and less processed food is likely a good generic answer that makes sense. And fueling your training rather than dieting on the bike
