I cut mine with coconut oil to make it last. Except lately. But, yeah I go through a ton of it really fast. Three tablespoons per day is about normal - but I also drink coconut milk and eat avocados, etc. If it's your main source of caloric fat (and a fine one it would be!) I can see going through a large jar (20 ounce?) every two or three weeks. I just invested in a huge stainless pot with a lid and now I make huge batches, like five large jars at once. And, of course, I am still steadily losing weight, what little there is left to lose. Big batches for the win. Tell your meat guy to save ALL his hard fat for you (heart is also a great source of hard fat) and call you when he is ready to sell it.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
