I'd not heard of Rhabdo. Don't think I had issues with that. My health/robustness isn't great anyway due to injuries and childhood Perthes disease.
There is one significant study into whether reductions of saturated fat consumption reduced heart disease which didn't find significant reductions. My problem with the study is that it was wimpy. They reduced intake by 30%. ***. Would you tell a heroin user to reduce by 30% then say the reduction didn't stop their addiction? Bad example. I was told dietary changes wouldn't help me but no harm in trying. Dropped (saturated animal fats) intake by more than 90%. Doctor says "Wow your results are good, that's very impressive."
What your body wants as fuel for exertion is odd. I've done one extended duration ride in recent years (24-hour ride), about 260miles. By the end of it I would have sold my children for some soup and could not face anything sweet. Beer tasted mighty good tho'!
Baked beans are very very good. At the end of a 60mile overnight ride, with another 60miles to go, my daughter was out of it, couldn't face food, wouldn't eat, but wanted to keep on eating. I made her eat 3 spoonfuls of beans (all she could stomach). Within 15min she was back to a more coherent state and could sensibly eat.
