I’ve always felt more comfortable working out while fasted. It is just for a long time I didn’t have the ability to sprint as much. When running I almost enjoyed how my body felt. I found that my fasted runs where I didn’t feel like I was pushing was nearly as fast and my fastest runs in the fed state. When I did push a fasted run my times would be better. So I was running faster even though I didn’t feel like it.

You mentioned bacon which is a highly processed meat. I like bacon too, however I don’t think it should be a stable. Saturated fats are probably better for cooking, so I understand butter, lard, etc. There are a lot of people are pushing more than 50% fats in the diets. People groups with high fat diets don’t seem to have long lifespans. However the biggest problem I have with ketogenic diets is the risk of poor nutrition because the diet is highly restrictive, things like fruit, nuts and many vegetables are avoided or at least limited, Very few people actually eat enough dark greens to make a difference nutritionally. At least I find it too hard to actually eat enough of them to make a good diet. Extreme diets tend to have nutritional problems, for example vegans have to worry about fat soluble vitamins.

It just seems to me that if someone is doing ADF and avoiding processed foods (mostly the added suger), then that should be more than enough for fat loss and the focus should be on nutrition on the days that eating is done.
