In the early days, the changes in bloods are not necessarily immediate. Your body, and in particular the digestive enzymes it produces, are primed by experience.
When I was on the downward trend, I used to find I would toddle along with scores of x or y, then for no material reason, my bloods would drop a notch, then stay there. So, you do need to be patient. If your eating plan is robust, and you stick to it, you should see results. Right now you are still training your body to accept you want it to run much lower. It's trying to keep you higher, because that's been your body's comfort zone for quite some time. You need to help it understand who is the boss.
