Trying to lose weight? Protein is your best friend. These foods will keep you fuller for longer, regulate your metabolism and help build lean muscle.   1. Egg whites They don’t taste as awesome as whole eggs, but egg whites are much lower in fat. Eggs (whole or not) are high in leucine, a muscle-building amino acid. Egg whites contain around 11 grams of protein and zero fat per 100 grams.     2. Tofu This glorious spongy soy product is cholesterol free, relatively low in fat and contains around 11 grams of protein per 100 grams. It’s also a great source of amino acids. 3. Cottage cheese: It might lack visual appeal, but cottage cheese contains all essential amino acids, is super low in fat and contains around 10 grams of protein per 100 grams. Dairy is also an excellent source of L-Carnitine, which plays a roll in fat metabolism. 6. Whey Protein Whey is a by-product of cheese production, and whey protein is a product made by isolating the protein in this by-product. It’s usually found in powdered form as protein shakes or supplements. Whey protein isolates tend to be the lowest in fat, but any kind of whey protein is a great source of amino acids, especially leucine, a muscle building amino acid. 7. Skinless chicken Ditch the drumsticks and wings for a nice lean chicken breast. Most of the fat in chicken is concentrated in the skin, leaving the meat quite lean. 100 grams of skinless chicken breast contains around 22 grams of protein and around 2 grams of fat. Chicken is also good for fat-free cooking methods such as poaching. 8. Prawns If you’ve only ever had these sweet crustaceans crumbed and fried from the fish and chip shop, you’re missing out. Prawns are high in protein (around 20 grams per 100 grams) and contain almost zero fat. They are also high in omega3, magnesium and iodine, all good for maintaining metabolic health. 9. Peanut flour Peanuts are high in fat, so chowing down on handfuls isn’t a great idea, but peanut flour is usually defatted, meaning that it’s actually quite low in fat. 100 grams of defatted peanut flour contains around 52 grams of protein and one gram of fat. Use it in your protein baking, or just add water for spreadable peanut butter! 10. Chickpeas Chickpeas might be lower in protein and higher in carbohydrates than most other protein foods, but they pack a fibrous punch. Chickpeas are a great source of soluble and insoluble fibre. Insoluble fibre is a great way to increase the transit time of food in your tummy, leaving you feeling flat tummied and lighter, whereas soluble fibre soaks up water and slows digestion, keeping you fuller for longer.   4. Venison: Game meats tend to be leaner than traditional meats, and venison is no exception. It’s low in fat and high in protein with around 25 grams of protein per 100 grams. It’s also full of B vitamins that help regulate metabolism. 5. Kangaroo: If you’re not too concerned about eating an Aussie icon: kangaroo meat is lower in fat that most other red meats, and is loaded with metabolism-regulating B-Vitamins and L-Carnitine, which plays a roll in fat burning for energy. And it contains around 21 grams of protein per 100 grams. {nomultithumb}
