I agree, don't look at the scale to verify your successes. The scale doesn't account for so many other factors, like gained muscle or bone density, as tfarny said. I tend to look at my 'guns'. And they're getting firmer and firmer, so that's a success in my book.
I wouldn't sweat the grass-fed meat if you truly can't afford it, but you have to consider your grocery needs are going to change quite a bit. Buy your fruits and veggies before you buy your meat, and it may surprise you how much money you have left over for your meat. I spend around $50 a week on produce for a family of four, another $60 on grass-fed meat. However, we eat goat probably 4 days out of the week, fish another day, and chicken the other 2. My husband doesn't know it's goat; I call it chevon, and he thinks it's lamb, lol.
Anyway, I did have a point there. We're actually spending less on groceries now than before, even with the extra cost for grass-fed. We still buy milk, cheese, etc., but look at all of the things you don't buy when you're eating like this. No cereal, no bread, no junk food. I was amazed by how it all added up.
