Still not convinced that protein is the solution to many of your health problems? Well, here are three science-backed ways it upgrades your quality of life.
1. It Speeds Up Your Metabolism
Just as many of you take collagen for weight loss daily, you can do the same with protein-rich meals. Digesting protein burns calories, and eating more protein can increase your metabolism (8, 9, 10).
Protein has a high thermic effect (also called TEF), which refers to the number of calories your body uses to digest your food and put its nutrients to use. The thermic effect of protein is 20-35%, versus just 5-15% for fat and carbs (4).
With this in mind, it’s no surprise that increasing the amount of protein in your diet could account for an extra 100 to 300 calories burned per day compared to carbs and fat (11).
2. Protein Curbs Your Appetite without Deprivation
If late-night snack cravings are a familiar frenemy, protein might be your solution. When you eat more protein earlier in the day, you could prevent those sneaky cravings from even showing up in the first place.
Protein is very filling and quells your appetite with less food than other macronutrients (4). One of the ways protein does this is by reducing your level of ghrelin, a hunger hormone, while boosting a hormone called peptide YY that is associated with feeling full (12, 13).
In one study, this effect was so powerful that increasing protein intake from 15% to 30% of calories helped a group of overweight participants eat 441 fewer calories each day without feeling hungry or even trying to cut back (14).
If you want to trim some belly fat, one easy move is to replace some of the carbs and fats in your regular routine with protein. No need to make drastic changes—the change could be as easy as slightly trimming that serving of rice and adding a few bites of grass-fed beef in its place.
The best thing about this effect is that unlike other things people lean on to curb appetite—take caffeine, for example—you can be assured that you’re still getting all the nutrients you need while shaving off calories. Instead of masking hunger, you’re stopping hunger at the source by making sure your body is well fueled by the food you do eat.
3. Protein Supports Your Muscles
Nutrition is about more than weight loss. It’s about supporting a full and vibrant life that allows you to be your healthiest self.
Protein plays a part in this by increasing your lean muscle mass, protecting you from muscle loss, and supporting soft tissue repair (15, 16). Building healthy, lean muscle can help improve your overall health while increasing your metabolism and quality of life (17, 18).
And of course, for women, strong muscles gain an additional layer of importance as we age. Healthy muscles help keep our bones strong and lower our odds of developing osteoporosis and life-disrupting fractures. That in itself makes protein worth its weight in gold (19).
On top of that, protein elevates the health of your tissues, helping to ease soreness and aches so that you can spend more time and energy participating in your day (20, 21).
