Do not rely on meat for protein. Many foods other than meat contain protein. You can consume nuts, soy, tofu, or beans. You might choose to use some of these items as a main dish, or incorporate them into other recipes. To keep from getting worn out with any one food, mix up your protein rich foods.
To adopt a healthier lifestyle, try staying away from meat. Remember that you still need proteins in your diet and can still eat meat a few times a week. But you should also consider alternatives such as fish or eggs which are definitely much healthier for you, especially by reducing the risks of heart disease.
