Eating a high-protein diet can help with weight loss, so here are five foods you should consider adding to your meals. 1. Peanut Butter. Peanut butter is full of protein, low in carbohydrates and high in "healthy" fats. 2. Eggs. Eggs are great for weight loss, with one egg having 6 grams of high-quality protein. They're also full of vitamins and minerals. 3. Salmon. Although salmon is a fatty fish, it contains many essential omega-3 fatty acids and lots of protein. 4. Black Beans. Black beans are great to add to your salads or wraps as they are high in protein and fiber. 5. Chicken Breast. Lean meat like chicken is fantastic for losing weight as it is low-calorie but protein-dense, leaving you feeling fuller for longer.
