When you think protein, think building. You need it to build muscles, skin and hair; to build hormones and enzymes; even to build antibodies for a healthy immune system. Your body also uses protein for cell maintenance and repair and blood clotting.
Can Lean Protein Help You Lose Weight?
In the world of weight loss, protein provides satiety; It makes you feel satisfied for the longest period of time, longer than both carbs and fat. Ever wonder why your belly rages in hunger shortly after that morning muffin but stays calm and quiet after a hearty omelet? You guessed it: protein.
Protein aids in satiety by affecting the hormones that control hunger. It also has the highest thermal effect of food (TEF), meaning it burns the most calories during digestion, compared to carbohydrates and fats.
And we all know that protein helps build muscle, and muscle burns more calories (yes, even while you sleep) than fat.
What is Considered ‘Lean’?
The U.S. Department of Agriculture (USDA) defines lean meat as having less than 10 grams of total fat, 4.5 grams or less of saturated fat, and fewer than 95 milligrams of cholesterol in a 3.5-ounce portion. For a 1-ounce serving, lean meat should contain 2 to 3 grams of fat.
Lean meat provides fewer calories for equal amounts of protein than higher-fat meat. For example, consider different cuts of beef. One ounce of a lower-fat cut, such as a top round, offers 52 calories with only 2 grams of fat (0.75 grams saturated) and 8 grams of protein. That same single ounce of a higher-fat cut—say, ribeye steak—contains 83 calories, a whopping 6 grams of fat (3 grams saturated), and a comparable 7 grams of protein.
Some kinds of fish and certain plant proteins (like salmon and nut butters) have more fat. Still, it’s important to remember that these are heart-healthy fats in good sources of protein. I always recommend including them in your diet.
So, what exactly do I want you to put on your plate to meet those protein needs to help you lose weight and build your biceps?
How Much Protein Do We Actually Need?
How much protein you’re eating is probably not as important as the kind of protein you’re eating. Approximately 50 grams, or about 15% of your calories, is enough for the average adult to meet their basic daily needs. But I say: Consuming as much as a third of your daily calories from protein (about 112 grams) is both safe and beneficial.
Here are some of the very best sources of lean protein.
