I did the 3-days fasting for the first time in 25 years. So I was very careful with activity (plus really bad weather over here). My step counts for the 3 hungry days were 15k, 750 ;-) and 8k - so well beyond my norm. Today I am eating normally and will be slightly more active. The goal is to have my max during the Sat hike. 22km and 818m of total elevation gain will convert into +30k steps
