It has zero calories
One tablespoon of prepared z trim has 20mg sodium and 0.6 grams carb which is fiber. Zero everything else.
I have the powder and the prepared gel and will test them both out this weekend. They recommend replacing 25% of the fat with the gel at first, to see how well it works in your individual recipe. Some recipes can use as much as a 50% replacement. It's not intended to fully replace fat, but just to partially replace it, and reduce overall calories without affecting the end product.
I think this is a good excuse to make brownies
