Is weight loss the only reason behind "Dieting"? Isn't the "carnivore diet" around mental fitness? That's why I choose a low carb diet, mental and physical fitness(when I'm not actively exercising, I try to limit my carb/sugar intake to mornings before I run)

Endurance training on an empty stomach is a great ketone pathways excercise, the first few times are hard but get easier afterwards!

I can confirm. I was preparing from marathon some years ago and the fastest improvements I have seen were when I started going for runs on empty stomach in the morning.

But, I would make sure to give all my body needs immediately after the exercise.

Runs are better as well, some Sundays I don't eat, go for a 30k run on 14:00 and have a meal after. Feels great. Never do breakfast either, sometimes lunch if I feel like it otherwise just a big meal in the evening.

I do this, but usually more by accident than anything else— I lane swim (1hr) or do a bike ride (1.5-2hrs) first thing in the morning before I've had much of a chance to eat anything, and then afterwards have a big protein shake or some bacon and eggs.

I feel like I'd be prone to cramps if I tried push myself after having eaten much.

i will agree with the person above/below about exercising while fasting; it feels like a light pleasure and it is healthy!

now regarding about high carb intake, people go overboard on their minds when thinking about diet based on blogs and news websites... eating fruits and vegetables all day is completely different than eating refined flour stuff and regarding getting into a fast (ketogenesis) state, you can get into, easily by eating a low-PROTEIN diet too (but this one i do not remember the keywords of the papers i read but if you are interested in nutrition, worth taking a look)

here is a sample of human population which have the lowest index of mental disease, diet consisted of 64% carbs, 21% protein, and 15% fat | https://academic.oup.com/ajcn/article/108/6/1183/5153293

Ironically I eat a high carb diet for the same reasons. I think that is illustrative of the current state of dietary science haha :)

I highly suspect proper diet is quite variable based on genes/environment/etc. I wonder how mature (or not) dietary science is. We have this firm idea of allergies and vague idea of sensitivities, but I imagine there is a lot more nuance to how different people react to different foods.
