On the topic of Carb Counts, just memorize these (per Cup):

White Sugar: 192g
White Flour: 92g
Splenda: 24g
Milk: 12g
Hood Milk: 3g

Guar/Xanathan Gums, Liquid Splenda/Saccharine, and Stevia Extract (the non-fillered stuff) are Carb-Free. Knowing those allows you to quickly calculate the Carbs in a LC version of many HC Recipes. For example, if a recipe calls for 1/4 cup of Flour and you use Guar Gum instead:

92/4 = 23g reduction in Carbs for the entire recipe. Just didivde that by the number of servings to get the reduction per serving. For example, say it made 8 servings, that would be a 2.9g reduction per serving. BTW, as for Gravy thickened with Flour/Cornstarch...its really not that high in Carbs. Most gravy is actually pretty low in Carbs even with the Flour. But, it could be easily made without the Flour [subbing Guar, Xanathan, or one of those prepackaged LC thickeners,] so there's no reason to use it.

Here's another interesting tidbit, White Breads and Fried Potato Chips have about half their weight in Carbs, unless they have added Sugar [Cake, Fortune Cookies, etc...] 1 oz. is 28g, so there'd be ~14g of Carbs per ounce of any White Flour based coating, bread, cookie, croutons, etc...that does NOT contain added sugars. This does not apply to Gravies, Grits, Cream of Wheat, and such as they are diluted with large amounts of water.
