I just buy a box of 10 Capri Sun juice packets in whatever flavor seems appealing. They are 100 Kcal apiece, and I find it very easy to regulate my total caloric intake with them. It really doesn’t matter, and yes, they are high in sugar, but I need some glucose for my brain on the fasting days. The whole point is to shrink my stomach down so that a portion about 1/4 the size I was eating before is quite satisfying. You could do it with water alone, but I find that excruciating. Even Ghandi drank sugar water when he was fasting.
Again, the whole point is to prime yourself to exist comfortably on about 1500-1700 Kcal/day. I find that if I try to do it with just portion control it takes about a week to adapt to the smaller portions. The fast shortens that considerably.
It’s amazing how it all comes down to portion control/calories. My father, who at one point weighed nearly 500 lbs, alway used to say he suffered from an “overactive jawbone”.
