I believe that 30 days and nights of Water Fasting will do the Job.
Then switch to eating healthy foods with some exercise and that should do the trick.
My Belly Fat has shrunk significantly over the past 3 months of which I was doing some 2 and 3 days fasting. (works best during long days of fasting.)
When you see that Belly Fat shrink during your 30 days water fast; that is going to encourage you tremendously.
I guess we are the only brave souls to Water Fast during the month of October.
In November, I am going to "pig out" for Thanksgiving; and also for Christmas in December too, so I have to go BIG Water Fasting now, while I am motivated.
