Fish and Seafood
Fish and seafood are an interesting issue on a ketogenic diet. Usually, they are low-or- no-carb. (Some shellfish contain a few carbohydrates in the form of glycogen). On the other hand, as the nutrition gurus of the past few decades have hastened to point out, they are quite low in fat-even salmon, often labeled a “fatty fish”, derives, only 28 percent of its calories from fat. Whitefishes like cod drop down as low as 8 percent. For that reason, you can do cook your fish with plenty of fat by the top it with a fatty sauce, or you can pair it with a high-fat side dish.
A 6-ounce (170g) lobster tail as only 153 calories, 9 percent of them from Fat, and 1 gram of carbohydrate. Add a couple of tablespoons (28g) of lemon butter, and you’re up to 359 calories and 62 percent of Fat. Have 2 cups (94g) of romaine with a couple of tablespoons (28g) of vinaigrette on the side, you’re up to 515 calories and 70 percent fat- and still only 5 grams of total carbohydrate for the whole meal.
