I now realise it has more to do with calories than I appreciated.
This will perhaps not come as a surprise to my family and friends. They have said for a long time that I was perhaps losing too much weight. I countered that I am the ideal BMI, and healthy. Society nowadays has accepted heavier than is healthy as normal. Having said that I don't want to cause myself any problems, or health issues.
Over the last couple of days I have increased my food intake, and it's made a difference. I do feel a little more positive; despite my situation not changing.
I've had variable endurance, especially on faster club rides. Reviewing my meal logs I can see that weeks where I was consistently not meeting my needs resulted in disappointing performance.
Science, as I understand it, says lower intensity longer lasting exercise uses fat reserves and intervals of high load, carbohydrates. Well I don't carry much fat and so I must be using carbs to fuel most of my efforts. I'm also in danger of losing muscle mass; in addition to the amount lost due to advancing age.
I seem to sleep better when I eat more. It would be easy to just eat calorie dense foods, but that tends to be more processed than I like, and/or none vegan. I kid you not, some meals barely fit on my plate.
As always it's a work in progress, that I am now getting right more often.
