Can you say more about the diet change salty? How did it change? Why do you think it helped?
I was a carb junkie & when in a 'down' state carbs do not help. I cut out all sweets, most carbs & alcohol for over 6 months. Ate salad for lunch rather than sandwiches, had no potatoes at meal time, just extra veg, no breakfast cereal, just wholemeal toast. It was tough at first, but took all the docs advice & it worked for me. Lost about 2 stone in 3months too which was a bonus
Sometimes as cyclist we are obsessed about carb loading, but I was overdoing it & it wasn't helping me mentally. When I did cut my crabs right down I still managed a 16 mile commute & 100 mile rides with no issues
Nowadays on a 100 mile ride I eat a good breakfast, generally 2 slices of toast, bacon, eggs & mushrooms & can manage most of the ride on that. Usually get to around 80 miles before needing to refuel & a cereal bar is sometimes sufficient to see me home. It's probably not normal, but I seem to manage ok now without massive carb loadings 👍
