Meat
Meat is the basis for many ketonic diets, because meat does not contain any carbohydrates. When you're on a ketonic diet, you should eat a combination of fatty and lean meats. Eating too many fatty meats can raise your cholesterol levels, so be sure to balance your consumption of meat with plenty of lean meats. For fatty meats, choose cuts of meat like beef and pork ribs, shoulder and belly. Chicken and turkey thighs work well too. For lean cuts of meat, choose chicken and turkey breast and sirloin, flank, round and tenderloin of beef and pork. Fish is one of the best ketonic diet foods because some types of fish, like salmon and sardines, are loaded with heart healthy omega-3 fatty acids.
