I'm Tamera. I went through the weight-loss process as a client before becoming a coach, so I know what it feels like to stand in a grocery aisle and not know which product is the better choice. Karen and I create these lists to make that decision simpler. Every product was evaluated in the same way: we bought it ourselves, sampled it in our kitchen, checked its label, judged its taste, and calculated its price per serving. Those standardized scores, rather than brand popularity or sponsorship, determined the ranking below.
Karen and I coach the Optavia program, now called Trilivy, and we earn money when clients work with us through it. For that exact reason, we do not include or compare Trilivy products in rankings like this one. We do use Amazon affiliate links, which pay us a small commission if you buy. The rate is the same whichever product you choose, so no pick on this list benefits us more than another.

What Should You Look for in Whey Protein for the Carnivore Diet?
Whey is made from milk, so strict carnivore followers avoid it. Flexible followers include dairy. Our carnivore diet guide explains both versions of the plan. Every pick here is unflavored, because flavored powders add sweeteners and gums.
Check the ingredient list first. Raw Organic Whey and Heart & Soil each state a single ingredient. Naked lists whey isolate and sunflower lecithin. Isopure adds vitamins, so Isopure has the longest label here.
Next, check the type and the carbs. Isolate removes more lactose, fat, and carbs than concentrate. Naked and Isopure each state zero carbs. Heart & Soil is a concentrate, so its lactose is higher.
Finally, check the price per ounce and the bag size. These powders cost about $1.25 to $2.50 per ounce. Raw Organic Whey costs least per ounce but needs a $99.99 upfront purchase. Isopure costs least upfront at $32.90.
