My weight has been stable in the three months since stopping.

That's why you should eat a low fat vegan diet.

The slowing metabolism is a myth.

If your base calorie requirements drop because you have lost a bunch of weight, but you don't change your eating behavior after stopping the fast, then of course you will end up gaining the weight back. They have done studies on the "World's Biggest Loser" contestants that show this. The facile interpretation is that you "slowed your metabolism".
