Eggs
Eggs are a popular source of protein for good reason. Not only are they easily tailored to your tastes, but they can also keep you full throughout the morning (which is great for curbing cravings and losing weight).
"Eggs are an excellent source of protein, nutrients, and healthful fats. A variety of studies have shown that eggs can help people feel more satisfied and stop them overeating," Medical News Today explains. "For example, one study found that a group of women who ate eggs instead of bagels for breakfast felt fuller for longer and ate fewer calories throughout the day."
Tofu
Tofu is a popular plant-based protein, especially for vegetarians. But there's room for this healthy food in almost any diet. Plus, it contains plenty of other nutrients besides protein, adding to its health benefits. According to BBC, "Tofu is a good source of protein and contains all nine essential amino acids. It is also a valuable plant source of iron and calcium and the minerals manganese and phosphorous. In addition to this, it also contains magnesium, copper, zinc and vitamin B1."
Chicken
Chicken is another popular source of protein that is low in calories. "One roasted chicken breast without skin contains 53 grams [of protein] and only 284 calories," per Healthline. With that in mind, if your diet is low on protein, try adding more chicken to your diet.
