Hi Alan, I have got to say I ran out of ‘juice’ doing things that required more physical energy for the first seven weeks, my blood pressure is always on the low side and has been lower on this diet BUT…BUT things are resolving. Rather than have a fit of ‘I’m about to faint’ I now eat a larger meal before physically demanding exercise. It helps. At least it does for me. So I may eat 900 calories on a day I have done a particularly strenuous hill walk but over the week it averages out as I often have 700 cals on other days.
Like you have said – keep at it, things will only get better 🙂
