I have been attempting to hike about 40 miles a week and have done so for three weeks. I am seeing good weightloss. However, I couple this with 12 to 20 hr fasts on weekdays, eating only after I finish the hike in the afternoon. I control the calories and carbs I eat and only let loose on weekends. Anybody else do similar to this and saw results? What additional benefits have you seen healthwise? I want to try to keep this up all summer and maybe even after. Any advice on maximizing potential weightloss and efficiency? I've dropped close to 20 pounds since I've started doing this 3 weeks ago.
