The Science of Fasting

I'm on the fasting bandwagon. Over the past couple months I've been doing ~24 hour fasts fairly regularly. My longest fast so far is about 3 days. I'm currently about 50 hours into an attempt at going for 7 days. If I end up just going for 4 or 5 days I'll be satisfied -- I figure aim high and if I fall a bit short it'll still be a success.

I do allow myself black coffee, tea, some coconut water with stevia leaf, and an occasional fish oil capsule during my fasts. I haven't been brave enough to do a pure water fast yet.

As long as I drink plenty of liquids there is no issue with hunger. Physically, I feel great while fasting. It's more of a mental challenge than anything.

I've lost a little over 6 lbs in two days. I'm down a total of around 25 lbs from when I was at my heaviest. I used to be somewhat of a health nut, but let things spiral out of control over the past couple years.
