I can tell you don't cook your own meals.
More credence to the tag of 'know-it-all'.
A kilo of low grade beef mince has far more fats and oils than you can metabolise in a day without building adipose tissue.
Why on Earth are you attempting to eat an entire kilogram of mince at once? Did you know that you can actually cut meat before you cook it? You later prod me by suggesting I have no conception of portion size -- highly comedic.
I get all the fat I require from vegetables and fish (which I eat a lot of for cultural reasons).
Are know-it-all-ism and brain-dead proportion sizes cultural, too?
Please excuse my cultural inexperience. I didn't realise that the mentally retarded idea of destroying the fat in meat, and then buying more food to get nearly identical fat, was cultural.
When I simmer a single meals worth I can fill half a cup with just fat. Just because it's monousaturated doesn't mean I can just drink it and call such a massive consumption "healthy."
Did you ever consider leaving the fat in the meat and not cooking as much? I suppose you must have, given your know-it-all status.
Know your portions, learn to cook.
This is a comma spliced sentence, but since you're a know-it-all, I suppose you're intentionally making grammatical mistakes.
Anyway, I don't want to interrupt the hours of cooking you have to do, given that you like to cook and partially destroy kilograms of meat at once.
Off to your cooking duties, know-it-all.
