Fat satiates appetite. You are better off getting kcals from fats, particularly healthy fats than most carbs. Glycemic index is important. You seem to be defending your position on fat. No need, again, I don't give a shit what you eat. Or what your view on fat as a macro is. I don't control my fat intake, I am in great shape for a late 50s male, and I don' get paid to train. Crazy right?
All I said is I haven't tried it because it has a shit ton of calories versus lean meat. I should've known you can't say anything about fat on the internet without starting a bro-science, nutritional debate, that will almost definitely turn into a dick measure contest and "do you even lift bro?"
I'm glad you can eat what you want and extra calories don't matter for you. They do for the vast majority of the country. Yes, fat can make you feel full sooner and longer, but you can still consume an extreme amount of calories on fat.
Again, I don't eat it because I try to watch my calories. Why? Because I tend to slowly gain weight when I don't, even though I do multiple hours of intense cardio and weight lifting a week as well as being generally active in the evenings and weekend.
Also, fat floats around in your blood, it'll ruin a platelets donation if you donate within 12 hours of eating a high fat meal. Maybe that doesn't cause any issues, but I have my doubts.
