Aside from water, proteins are the most abundant compounds in the body. They’re responsible for everything from building tissues to making your hair and nails strong and shiny.

But are you getting enough protein? Check out the five symptoms below to see if you need to boost your intake. Ready for a top up? Chow down on a range of proteins, including animal products, legumes, nuts and whole grains.

If you’re always on the run or struggling to pack enough protein in your meals, you can also try a quality protein powder for more good stuff on the go. (We love the guys at Bare Blends because their protein powders are natural, sugar-free and don’t have any added nasties!)

How to tell if you need more protein

I Quit Sugar

Quitting sugar began as an experiment for Australian journalist and author, Sarah Wilson. But once Sarah quit, her energy, skin and wellness improved so much, she just kept going. And going. And feeling better and better. The results spurred Sarah to write the New York Times best-seller I Quit Sugar and, in consultation with experts around the globe, Sarah launched IQuitSugar.com and her hugely successful online 8-Week Program (8WP) to help others quit sugar, too. Today, IQuitSugar.com is read by more than 1 million every month and has helped over 1.2m people quit sugar worldwide.
