Since my last post I’ve made a bit of progress, but also been through another roller-coaster, from 112.8 to 116(!) back to 112 now.
A few things were causing this, and I have been able to identify them, not the least of which was my bad habit of snacking in the evening that got a bit out of control. I’ve put a stop to that, and the results are immediately visible.
Now my diet is actually quite sober, but OK. In the morning quark, in the afternoon a warm meal, and in the evening some salad. That’s all, nothing more, and guess what? It works!
