that shit about eating lean meat only is not exactly correct, in so far as that you need to switch off carb-burning and switch on fat-burning genetic expressions to actually get rid of already stored body fat

so that generally plays out as:
- ketosis, 50g of carbs a day, or fewer
- eating enough fat to compensate for your level of activity
- raising your level of activity you fat neckbeard

you have to actually intake sufficient fats, from meat, in order to tell your body to re-spec for fat-burning day-to-day operation

if you have no body fat to begin with then you'll actually need even more to make up the difference for cutting out carbs
