This was worth logging in for.
I was overweight and staring down 50, so I did some research and decided to try it.
I did a 7 day water fast followed by a mostly keto style diet, but really just sticking to food that's been on the planet for longer than 100 years, no processed chemical foods. I lost maybe 10 pounds during that week but the weight just kept falling off. Down from 40's to 34's and even 32's after about 9 months of sticking to real food, cut back(not out) on sugar and bread. My blood panels showed no problems with cholesterol etc after eating bacon and eggs for breakfast for months. homemade soups etc for dinner.
Fasting is part of a natural cycle, your body uses the time when digestion is shut down to heal itself.
Don't believe me, prove me wrong.
