WingZero,
I understand what you're saying. But it isn't uncommon for rapid weight loss when you get off carbs.
What is puzzling is that you are losing weight while on prednisone, although I did too. Maybe because of SCD diet, we're just the unusual pattern of not gaining weight with prednisone.
However, from what I see that you are eating, you're not taking in enough food and enough calories.
Olive oil and Ghee are great.
IMO, you need to increase your food intake/quantity so you can get enough calories.
