This new salt data could be something for you. My weight has been static for over 12 months. In the last 2 weeks I’ve increased salt (Himalayan) significantly, when fasting and not. Nothing conclusive but I think my static weight is down a couple of pounds.
I believe it helps dampen down insulin, it definitely makes fasting easier, which accounts for small weight reduction.
I think I’ve only added about 1 extra teaspoon/day of salt so far but I believe 2 or 3 teaspoons might be better. So I’m going to up it more.
Like being scared of eating fat because I spent so many years in fear, I’m having to get over my salt fears now.
