An interesting nutrition experiment
Today I felt curious as to what happens to your available energy before and after eating. Obviously, after eating there has to be more. Yet, does this help me lose weight, or does forcing my body to operate on empty help more? So I did two identical rides. Having ridden 50 miles yesterday I limited it to recovery riding
1) Pre breakfast at 4:45am 24km average speed 22km/h. Time for the round trip 1:10. I deliberately rode at an easy pace. Pre ride weight was 92.2kg. Post ride 91.7kg. I took a bottle of water only
2) After breakfast at about 9am: 24km as before, but the average speed jumped to 24km/h. Time 1 hour exactly. I rode to the same percieved effort, but was noticably faster. I also took as overkill a bottle of 1/2 strength gatorade and made sure to drink it all. Pre ride weight 92kg, post ride weight 91kg.
Those weight changes are of course 95% water related and I be sure that by this evening I'll be back up at 92ish or a bit below again. I can conclude that eating before riding makes it much easier (kind of obvious there!) but in terms of steady weight loss I still feel that short, slow rides with no nutrition actually help burn fat faster.
