If you're worried about your dietary choices, go for leaner, low-fat proteins over less healthy options. Turkey, poultry, and seafood are good protein choices as they're low in fat and tend to have fewer calories. If you're a vegetarian, protein can be found in eggs, nuts, beans, soy products, and cheeses. Stick to low-fat, healthy cheese options. The manner in which you prepare protein can cause it to have more or fewer calories. Avoid frying protein or cooking it in heavy oils or butter. Try using heart-healthy olive oil when cooking protein. Consider boiling or poaching eggs instead of frying them. Do not use too much salt. Excessive salt intake can cause problems like high blood pressure. Processed meats, such as those found in frozen food or deli meats, tend to be higher in fat and calories. They also tend to have a higher overall salt content. Opt for fresh meats when possible.
