Half-and-half milk

If plant-based milk doesn't do it for you, you should try a dependable dairy alternative; chances are, you already have a carton in your refrigerator. According to the USDA, a 1-ounce portion of half-and-half, which is made from milk and heavy cream, has roughly 1 gram of net carbohydrates. In addition to having low carbs, half-and-half has a fat content of between 10.5 and 18%, making it ideal for a high-fat diet like the ketogenic diet (via FDA). You can therefore make a convenient glass of milk by combining it with cold water in addition to adding it to your coffee. Although it's a distinct product from heavy cream, the two can occasionally be used interchangeably.

The viscosity of half-and-half and heavy cream is one of their main differences. Because heavy cream is so thick, substituting it for half-and-half can provide extremely rich results that, depending on what you're making, may or may not be preferred. Otherwise, substituting half-and-half for heavy cream is often not too harmful. Before buying, read the label to be sure the kind you want has no added sugar or sweeteners, just like with all other keto-friendly milk.
