Fat-fueled brain: unnatural or advantageous?
The main problem I have with ketogenic diets is that it&#x27;s actually quite difficult and sometimes expensive to eat a 90-95% fat diet. I tried it for a while, and since I couldn&#x27;t have carbs OR too much protein, I had several instances where my dinner in a pinch was melted down cheese and half-n-half. Your diet basically becomes cheese and avocados with some, but not too much, salmon or chicken. I&#x27;m not arguing that it doesn&#x27;t work for a good subset of people, but it&#x27;s not the kind of diet that&#x27;s easy to keep up over time or is all that economically feasible for some. Keto diets are actually <i>more</i> restrictive than vegan or kosher or halal, and it&#x27;s not a surprise that they&#x27;re mostly prescribed for epilepsy - it definitely feels like a &quot;sick person diet&quot;.<p>I also wonder if it&#x27;s possible to work out while doing keto. Since muscles use glycogen to work, and the keto diet is intentionally low in glycogen, does that make weight training and cardio harder? Especially the former, since you&#x27;re limited in how much protein you can eat, and strength training benefits from having ~150g of protein per day.
