Water Fasting and Exercise

I started to go to the gym again since last week and I really didn't want to stop for my 3^rd Water Fast, so I have planned on keep on going, trying to listen to my body if I feel good or too weak to exercise. This morning I took really 20 minutes and went upstairs for a quick walk on the treadmill and few reps for my abs, it was late though so I left pretty soon to start to work. For some reason I don't enjoy waking up early in the morning anymore, not sure if I'm having a lack of Vitamin D lately, I should take some blood tests after this fast.

I did some researches regarding exercising during a fast, mostly are referring to the IF – Intermitting Fasting, which is a different thing if compared with Water Fast. I do believe that for prolonged Water Fast – like more than 15/20 days – it's almost impossible keeping an exercise regimen, too weak to barely walk so not in discussion strenuous activities. But overall for short fast I don't think is so negative keeping a moderate physical activity, without going crazy obviously. One thing that I found though, that was interesting, is that in terms of body response a fast is very similar to a workout, for the glucose level and things like that, the body reacts similarly; I'm not a doctor though so I can't comment on this for sure, what I believe though is that we should always listen to our bodies, without stressing it too much. Even in the past men were supposed to have strengths to hunt and get food, those strengths might have been required in situations when food was scarce so similar to a fast.

I didn't feel going more than those 20 minutes today though, I will try again tomorrow early in the morning – since I have an interview during lunch time I won't be able to take the usual break, but as long as I do a decent workout in the morning I am happy; I still have the lactic acid in my legs from Sunday class!
