A lot of good stuff here. I too prioritize walking as my cardio (usually weighted/incline)
I might adjust a bit in that, folks can only work with what’s accessible/affordable for them, and while we can all learn to like and tolerate foods, it’s also good to focus on things you LIKE to eat. Some of the produce at some of the grocery stores looks (and is) gross. Some whole foods taste like garbage, even when cooked. Like all things, it’s about balance. Buy and eat things you are going to enjoy. I wouldn’t tell anyone to avoid supplements or even processed food. There are plenty of good whey protein powders that have less than 4 ingredients, and plenty of powders they are just pure whey with nothing else added (all of which can be easily bought and shipped from Amazon). I enjoy having a shake after a workout of any kind, any day of the week. No, I’m not going to sub out my simple whey protein shake with a 10oz steak and potatoes because that’s not practical for me, and again, I find the shake to be delicious and enjoyable, and convenient. A lot of folks fall into this bucket and it’s OK to prioritize ‘this’ overall whole food when needed. I also love breakfast cereal, just like I did as a kid. They’re actually plenty of really good breakfast cereals out there with very simple ingredients, and no mysterious additives. Some are expensive, others not too bad at all. If I time it right on Amazon or Costco or whatever, I’ll buy in bulk. I’ll even use the protein shake as the milk for the cereal sometimes - so damn good. Point is, there are plenty of “processed foods” out there (and canned goods no bad additives) that are perfectly fine to include in a really good diet. As long as they are not ultra processed
