36 hour fast

I’ve been feeling no hunger between meals despite fasting between 7pm and 11am each day, sometimes longer. So I decided to test my fat burning by having an extended fast.

I started out without any specific target other than to not eat at 11am on Wednesday and see how long before I got hungry. I did a Tabata session on bike on Wednesday morning just to add some extra glycogen depletion. 

Needless to say I went all day without any great hunger so I extended my normal 16 hours to 36 hours. 

I awoke on Thursday feeling hungry but did my planned “easy ride” fasted. The ride was anything but easy. The fast seemed to make a massive difference. I was struggling to control my heart rate even at 100W avg. 

Take outs:

1. Keto definitely seems to reduce my appetite and cravings and make it easier to do longer periods of fasting
2. Exercising at the end of a long fast is still much harder than normal. Maybe that will change as my body adapts. But for now low intensity is the way to go.
