I think writing a fictional dialogue can be a useful exercise to explore ways of better presenting information. There were 2 passages in Sisson’s piece that stood out to me as being similar to conversations I’ve had as of late and thus worth quoting:

Actually, you know how you asked how I never quite need coffee? It’s because I’m fat-adapted. Thanks to my high-fat diet, I have the metabolic flexibility to tap into my stored body fat whenever I need to. See, we store body fat because it’s a fantastic energy source. It burns clean and we can store upwards of tens of thousands of calories worth. I’m reasonably lean with fairly low body fat and I still have over 50,000 calories worth on my body. Meanwhile, I can only store about 500 grams of sugar in the form of liver and muscle glycogen. It serves its purpose to be sure, but you can’t rely on glycogen indefinitely without constant refills. That’s where your need to snack comes from. It also explains why your energy levels dip an hour or two after eating.

It’s more that I’m against unnecessary carbs in sedentary people. When you’re sedentary, you’re usually insulin resistant with higher baseline levels of insulin. This is bad because insulin inhibits the release of fat from body fat stores. When an insulin resistant person consumes carbs, they secrete more insulin than normal, which causes greater retention and storage of fat. Athletes need more carbs because they’re burning through their glycogen stores. Plus, they can handle more because their insulin resistance is so low. I’m a fairly active guy myself, but I’m not an elite athlete or exercise addict. I find I just don’t need much more than 150 grams of carbs. Maybe a bit more on really heavy workout days. Often far less.
