Sanoisin, että sopii. En ainakaan keksi mitään syytä, miksi ei sopisi, ja nopea google "peanut oil" ja "low carb" ainakin tuottaa sivuja, joilla ko. tuotetta suositellaan karppaajille. Esim.
A low-carb diet is a high-fat diet. Eat enough fat to satisfy your hunger. However, all fats are not created equal. A new look at nutritional research indicates that saturated fat is not so bad for you after all, especially the type containing stearic acid (found in beef). Other good fats include coconut oil, olive oil, butter, lard, fish oil, tallow, palm kernal oil, peanut oil, and flaxseed oil. Fats to avoid include margarine, shortening, corn oil, safflower oil, soybean oil, and cottonseed oil as these oils are processed at high temperatures and may contain too many of the harmful trans fats.
