Your Hair is Falling Out
You may find hair in your brush, but it shouldn’t be clumps or large amounts. Protein is the building block of all of your cells—your hair follicles included. But if you typically don’t get enough protein, you may notice that your strands start thinning (although, keep in mind, this can also be a sign of other conditions, like thyroid trouble).You Feel Weak
We all know that protein is essential for building muscle. If you don’t get enough of it, your muscles may start to shrink over time. As a result, you may feel weak and unable to do the exercises you once excelled at.
You Get Sick Constantly
“Protein is needed to build all the compounds in our immune systems,” says Blatner. If you seem to be infection prone or catch the cold more than your friendse—and you’re in good health— your deficient food friend, protein, may be to blame.
You Crave Sweets
“If all you ate in the morning was a handful of cereal, you’re going to get energy right away, then your energy is going to wane,” Blatner says. One of the first signs you’re low on protein: You start craving sweets and feel like you’re never quite full.
One of protein’s biggest chores is to keep your blood sugar regulated —which means if you’re lacking, your glucose levels will be all over the place, encouraging you to reach for a quick fix like candy.
So how do you think you are doing? Feel deprived or just about right?
